* Remove address from GPLv2 headersPatrick Georgi2015-05-2130-41/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
* build system: use archives, not linker action to shorten command linesPatrick Georgi2015-05-201-4/+4
| | | | | | | | | | | | | | | | | Intermediate linking may distort linker behavior (in particular related to weak symbols). The idea is that archives are closer to 'just a list of object files', and ideally makes the linker more predictable. Using --whole-archive, the linker doesn't optimize out object files just because their symbols were already provided by weak versions. However it shouldn't be used for libgcc, because that one has some unexpected side-effects.

* cache: Add arch_program_segment_loaded call to arm and arm64Furquan Shaikh2015-05-111-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | arch_program_segment_loaded ensures that the program segment loaded is synced back from the cache to PoC. dcache_flush_all on arm64 does not guarantee PoC in case of MP systems. Thus, it is important to track and sync back all the required segments using arch_program_segment_loaded. Use this function in rmodules as well instead of cache_sync_instructions which guarantees sync upto PoC.

* rk3288: Handle framebuffer through memlayout, not the resource systemJulius Werner2015-04-171-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've traditionally tucked the framebuffer at the end of memory (above CBMEM) on ARM and declared it reserved through coreboot's resource allocator. This causes depthcharge to mark this area as reserved in the kernel's device tree, which may be necessary to avoid display corruption on handoff but also wastes space that the OS could use instead. Since rk3288 boards now have proper display shutdown code in depthcharge, keeping the framebuffer memory reserved across the handoff (and thus throughout the lifetime of the system) should no longer be necessary. For now let's just switch the rk3288 implementation to define it through memlayout instead, which is not communicated through the coreboot tables and will get treated as normal memory by depthcharge. Note that this causes it to get wiped in developer/recovery mode, which should not be a problem because that is done in response to VbInit() (long before any images are drawn) and 0 is the default value for a corebootfb anyway (a black pixel). Eventually, we might want to think about adding more memory types to coreboot's resource system (e.g. "reserved until kernel handoff", or something specifically for the frame buffer) to model this situation better, and maybe merge it with memlayout somehow.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | checkstack() runs at the end of ramstage to warn about stack overflows, and it assumes that CONFIG_STACK_SIZE is always the size of the stack to check. This is only true for systems that bring up multiprocessing in ramstage and assign a separate stack for each core, like x86 and ARM64. Other architectures like ARM and MIPS (for now) don't touch secondary CPUs at all and currently don't look like they'll ever need to, so they generally stay on the same (SRAM-based) stack they have been on since their bootblock. This patch tries to model that difference by making these architectures explicitly set CONFIG_STACK_SIZE to zero, and using that as a cue to assume the whole (_estack - _stack) area in checkstack() instead. Also adds a BUG() to the stack overflow check, since that is currently just as non-fatal as the BIOS_ERR message (despite the incorrect "SYSTEM HALTED" output) but a little more easy to spot. Such a serious failure should not drown out in all the normal random pieces of lower case boot spam (also, I was intending to eventually have a look at assert() and BUG() to hopefully make them a little more useful/noticeable if I ever find the time for it). BRANCH=None BUG=None TEST=Booted Pinky, noticed it no longer complains about stack overflows. Built Falco, Ryu and Urara.

* rk3288: Add CBMEM console support and fix RETURN_FROM_VERSTAGEJulius Werner2015-04-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we can now reduce our vboot2 work buffer by 4K, we can use all that hard-earned space for the CBMEM console instead (and 4K are unfortunately barely enough for all the stuff we dump with vboot2). Also add console_init() and exception_init() to the verstage for CONFIG_RETURN_FROM_VERSTAGE, which was overlooked before (our model requires those functions to be called again at the beginning of every stage... even though some consoles like UARTs might not need it, others like the CBMEM console do). In the !RETURN_FROM_VERSTAGE case, this is expected to be done by the platform-specific verstage entry wrapper, and already in place for the only implementation we have for now (tegra124). (Technically, there is still a bug in the case where EARLY_CONSOLE is set but BOOTBLOCK_CONSOLE isn't, since both verstage and romstage would run init_console_ptr() as if they were there first, so the romstage overwrites the verstage's output. I don't think it's worth fixing that now, since EARLY_CONSOLE && !BOOTBLOCK_CONSOLE is a pretty pointless use-case and I think we should probably just get rid of the CONFIG_BOOTBLOCK_CONSOLE option eventually.)

* timer: Reestablish init_timer(), consolidate timer initialization callsJulius Werner2015-04-142-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have known for a while that the old x86 model of calling init_timer() in ramstage doesn't make sense on other archs (and is questionable in general), and finally removed it with CL:219719. However, now timer initialization is completely buried in the platform code, and it's hard to ensure it is done in time to set up timestamps. For three out of four non-x86 SoC vendors we have brought up for now, the timers need some kind of SoC-specific initialization. This patch reintroduces init_timer() as a weak function that can be overridden by platform code. The call in ramstage is restricted to x86 (and should probably eventually be removed from there as well), and other archs should call them at the earliest reasonable point in their bootblock. (Only changing arm for now since arm64 and mips bootblocks are still in very early state and should sync up to features in arm once their requirements are better understood.) This allows us to move timestamp_init() into arch code, so that we can rely on timestamps being available at a well-defined point and initialize our base value as early as possible. (Platforms who know that their timers start at zero can still safely call timestamp_init(0) again from platform code.) BRANCH=None BUG=None TEST=Booted Pinky, Blaze and Storm, compiled Daisy and Pit.

* CBFS: Automate ROM image layout and remove hardcoded offsetsJulius Werner2015-04-141-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Non-x86 boards currently need to hardcode the position of their CBFS master header in a Kconfig. This is very brittle because it is usually put in between the bootblock and the first CBFS entry, without any checks to guarantee that it won't overlap either of those. It is not fun to debug random failures that move and disappear with tiny alignment changes because someone decided to write "ORBC1112" over some part of your data section (in a way that is not visible in the symbolized .elf binaries, only in the final image). This patch seeks to prevent those issues and reduce the need for manual configuration by making the image layout a completely automated part of cbfstool. Since automated placement of the CBFS header means we can no longer hardcode its position into coreboot, this patch takes the existing x86 solution of placing a pointer to the header at the very end of the CBFS-managed section of the ROM and generalizes it to all architectures. This is now even possible with the read-only/read-write split in ChromeOS, since coreboot knows how large that section is from the CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be changed on systems that place other data next to coreboot/CBFS in ROM). Also adds a feature to cbfstool that makes the -B (bootblock file name) argument on image creation optional, since we have recently found valid use cases for CBFS images that are not the first boot medium of the device (instead opened by an earlier bootloader that can already interpret CBFS) and therefore don't really need a bootblock. BRANCH=None BUG=None TEST=Built and booted on Veyron_Pinky, Nyan_Blaze and Falco.

* CBFS: Correct ROM_SIZE for ARM boards, use CBFS_SIZE for cbfstoolJulius Werner2015-04-141-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some projects (like ChromeOS) put more content than described by CBFS onto their image. For top-aligned images (read: x86), this has traditionally been achieved with a CBFS_SIZE Kconfig (which denotes the area actually managed by CBFS, as opposed to ROM_SIZE) that is used to calculate the CBFS entry start offset. On bottom-aligned boards, many define a fake (smaller) ROM_SIZE for only the CBFS part, which is not consistently done and can be an issue because ROM_SIZE is expected to be a power of two. This patch changes all non-x86 boards to describe their actual (physical) ROM size via one of the BOARD_ROMSIZE_KB_xxx options as a mainboard Kconfig select (which is the correct place to declare unchangeable physical properties of the board). It also changes the cbfstool create invocation to use CBFS_SIZE as the -s parameter for those architectures, which defaults to ROM_SIZE but gets overridden for special use cases like ChromeOS. This has the advantage that cbfstool has a consistent idea of where the area it is responsible for ends, which offers better bounds-checking and is needed for a subsequent fix. Also change the FMAP offset to default to right behind the (now consistently known) CBFS region for non-x86 boards, which has emerged as a de-facto standard on those architectures and allows us to reduce the amount of custom configuration. In the future, the nightmare that is ChromeOS's image build system could be redesigned to enforce this automatically, and also confirm that it doesn't overwrite any space used by CBFS (which is now consistently defined as the file size of coreboot.rom on non-x86).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On most platforms, enabling the console and exception handlers are amongst the very first things you want to do, as they help you see what's going on and debug errors in other early init code. However, most ARM boards require some small amount of board-specific initialization (pinmuxing, maybe clocks) to get the UART running, which is why bootblock_mainboard_init() (and with it almost all of the actual bootblock code) always had to run before console initialization for now. This patch introduces an explicit bootblock_mainboard_early_init() hook for only that part of initialization that absolutely needs to run before console output. The other two hooks for SoC and mainboard are moved below console_init(). This model has already proven its worth before in the tegra124 and tegra132 custom bootblocks.

* New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner2015-04-0611-372/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies with ToT and looked for red flags.

| | | | | | | | | | | | | | | | | | | | | | The struct prog serves as way to consolidate program loading. This abstraction can be used to perform more complicated execution paths such as running a program on a separate CPU after it has been loaded. Currently t124 and t132 need to do that in the boot path. Follow on patches will allow the platform to decide how to execute a particular program. Note: the vboot path is largely untouched because it's already broken in the coreboot.org tree. After getting all the necessary patches pushed then vboot will be fixed.

* Clean up architecture-specific KconfigsJulius Werner2015-04-021-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's an unfortunate side effect of our different-archs-per-stage mechanism that all src/arch/*/Kconfig files are always parsed with no if blocks to exclude them if they're not relevant. This makes it very easy to accidentally rely on a Kconfig default set by a totally different and not applying architecture. This patch moves a few Kconfigs from ARM and X86 that leaked out like this into a common Kconfig file for clarity. It also gives ARM64 its own BOOTBLOCK_CUSTOM mechanism so that it doesn't leech off the ARM one (currently not used by any board). In the future, we should maybe prefix all options in the arch/*/Kconfig files with the architecture name (such as X86_BOOTBLOCK_NORMAL and ARM_LPAE are already doing), to make it more apparent when they are used in the wrong place.

* arm: Prevent compilation of old, experimental SMP supportJulius Werner2015-04-022-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ARM SMP feature was added a long time ago and has never really been used by anyone since. We are still always compiling cpu_info() even though we don't use it, and it makes some dangerous assumptions about stack alignment that are not guaranteed anywhere. I'm planning to change the way the stack boundaries are defined. Rather than trying to work that into this unsafe, unused and hard to test feature, I think we should just seal it off with police tape and make sure that if anyone ever tries to use it again (which currently seems unlikely), they get forced to do their due diligence on making sure it works as intended.
