* mboot: fix cmdline; a few more layout tweaksH. Peter Anvin2009-04-264-30/+38
| | | | | | | | | | Fix module command lines (it was overwriting the main kernel command line); a few minor layout tweaks. In particular, we require the section header to be page-aligned, but not the subsequent sections. With this, I can get Xen to boot. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* mboot: skip --- marker; decompress all filesH. Peter Anvin2009-04-261-7/+5
| | | | | | | | | When walking the argument list we need to skip --- markers. Grub, and the old mboot.c32, seem to transparently decompress all files, not just the main one, so do the same. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* mboot: make sure we actually succeed when we finishedH. Peter Anvin2009-04-262-18/+44
| | | | | | | When we actually finished mapping the image, return 0 and don't bail. Add error messages to most failure cases. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* mboot: set up a stack even though the spec doesn't require itH. Peter Anvin2009-04-261-0/+18
| | | | | | | Set up a stack for the Multiboot OS even though it is not required by spec. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
