* Remove address from GPLv2 headersPatrick Georgi2015-05-2191-94/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* kbuild: automatically include SOCsStefan Reinauer2015-04-293-2/+8
| | | | | | | | | | | | | | | | | | | | | This change switches all SOC vendors and southbridges to be autoincluded by Makefile.inc, rather than having to be mentioned explicitly in soc/Makefile.inc or in soc/<vendor>/Makefile.inc. This means, vendor and SOC directories are now "drop in", e.g. be placed in the coreboot directory hierarchy without having to modify any higher level coreboot files. The long term plan is to enable out of tree components to be built with a given coreboot version (given that the API did not change).

* timer: Reestablish init_timer(), consolidate timer initialization callsJulius Werner2015-04-146-20/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Werner2015-04-142-50/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gpio: Extend common GPIO header, simplify function namesJulius Werner2015-04-102-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've had gpiolib.h which defines a few common GPIO access functions for a while, but it wasn't really complete. This patch adds the missing gpio_output() function, and also renames the unwieldy gpio_get_in_value() and gpio_set_out_value() to the much easier to handle gpio_get() and gpio_set(). The header is renamed to the simpler gpio.h while we're at it (there was never really anything "lib" about it, and it was presumably just chosen due to the IPQ806x include/ conflict problem that is now resolved). It also moves the definition of gpio_t into SoC-specific code, so that different implementations are free to encode their platform-specific GPIO parameters in those 4 bytes in the most convenient way (such as the rk3288 with a bitfield struct). Every SoC intending to use this common API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most 4 bytes in length. Files accessing the API only need to include <gpio.h> which may pull in additional things (like a gpio_t creation macro) from <soc/gpio.h> on its own. For now the API is still only used on non-x86 SoCs. Whether it makes sense to expand it to x86 as well should be separately evaluated at a later point (by someone who understands those systems better). Also, Exynos retains its old, incompatible GPIO API even though it would be a prime candidate, because it's currently just not worth the effort.

* New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner2015-04-0610-183/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This change is intended to provide finer control and clearer communication of intent after we added a new (optional) stage that falls under __PRE_RAM__, and will hopefully provide some robustness for the future (we don't want to end up always checking for romstage with #if defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) && !defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The __PRE_RAM__ macro stays as it is since many features do in fact need to differentiate on whether RAM is available. (Some also depend on whether RAM is available at the end of a stage, in which case #if !defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be authoritative.) It's unfeasable to change all existing occurences of __PRE_RAM__ that would be better described with __ROMSTAGE__, so this patch only demonstratively changes a few obvious ones in core code. BUG=None TEST=None (tested together with dependent patch).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds I2C emulation in software through raw toggling of the SDA/SCL lines. Platforms need to provide bindings to toggle their respective I2C busses for this to work (e.g. by pinmuxing them as GPIOs, currently only enabled for Tegra). This is mostly useful as a debugging feature, to drive unusual states on a bus and closely monitor the device output without the need of a bus analyzer. It provides a few functions to "wedge" an I2C bus by aborting a transaction at certain points, which can be used to test if a system can correctly recover from an ill-timed reboot. However, it can also dynamically replace the existing I2C transfer functions and drive some/all I2C transfers on the system, which might be useful if a driver for the actual I2C controller hardware is not (yet) available.

The SOC specific code needs to be kept in the respective source files, not in the common CPU code. As of now coreboot does not provide a separate SOC initialization API. In general it makes sense to invoke SOC initialization from the board initialization code, as the board knows what SOC it is running on. Presently all what's need initialization on 8064 is the timer.

Experience has shown that nearly every board needs either one or both of these hooks, so having explicit Kconfigs for them has become unwieldy. Instead, this patch implements them as a weak symbol that can be overridden by mainboard/SoC code, as the more recent arm64_soc_init() is also doing. Since the whole concept of a single "CPU" on ARM systems has kinda died out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had already been done on Storm/ipq806x, which is now adjusted to directly use the generic hook.) Also add a proper license header to bootblock_common.h that was somehow missing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new API is in use in depthcharge and is based around the "i2c_transfer" function instead of i2c_read and i2c_write. The new function takes an array of i2c_seg structures which represent each portion of the transfer after a start bit and before the stop bit. If there's more than one segment, they're seperated by repeated starts. Some wrapper functions have also been added which make certain common operations easy. These include reading or writing a byte from a register or reading or writing a blob of raw data. The i2c device drivers generally use these wrappers but can call the i2c_transfer function directly if the need something different. The tegra i2c driver was very similar to the one in depthcharge and was simple to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and replace the ones in coreboot. The Exynos 5420 driver was ported from the high speed portion of the one in coreboot and was straightforward to port back. The low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot and were replaced with the depthcharge implementation. BUG=None TEST=Built and booted on nyan with and without EFS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPI drivers for tegra and exynos5420 have code in them which waits for a frame header and leaves filler data out. The SPI driver shouldn't have support for frame headers directly. If a device uses them, it should support them itself. That makes the SPI drivers simpler and easier to write. When moving the frame handling logic into the EC support code, EC communication continued to work on tegra but no longer worked on exynos5420. That suggested the SPI driver on the 5420 wasn't working correctly, so I replaced that with the implementation in depthcharge. Unfortunately that implementation doesn't support waiting for a frame header for the EC, so these changes are combined into one. BUG=None TEST=Built and booted on pit. Built and booted on nyan.

It runs without stack and before coreboot makes any write accesses to be as compatible as possible with whatever state the system was left in by preceeding code. This also finally fixes the dreaded icache bug that wasted hundreds of milliseconds during boot.

* Add check_member macro to allow clean and easy struct offset checkingJulius Werner2014-09-2225-18/+39
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new static assertion macro that can be used to check the offsets in structures that overlay register sets at compile time. It uses the _Static_assert() declaration from the new ISO C11 standard, which is supported (even without -std=c11) by GCC after version 4.6. (There is supposedly also support in clang, although I haven't tried it... let's deal with compiler issues when/if they turn up.) I've added it to all structures for our current ARM SoCs for now, and I think every new register overlay we add going forward should use them (at least for the last member, but feel free to add more if you think it's useful).

| | | | | | | | | | | | | | | | | | | | The TPM driver expects to call i2c_read with zero address length. The i2c driver wasn't prepared to handle that particularly in the case of reads because it expected to send an address before switching over to read mode for the data. This change also fixes up the read and write calls to consistently be read32 and write32 instead of readl and writel.
