2013-01-04update CFLAGS for armv7David Hendricks
This updates $CFLAGS used for armv7. Most of them were just added to be consistent with what u-boot does. The important ones here are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions). I removed the hard float support because it got errors and coreboot should never use floats anyway. We're still having trouble with enums but I want to see how far it gets with this patch. Also, put the flags in a form that makes diffs easier to read. It's almost impossible otherwise. Finally, move some flags to the architecture Makefile, and rely on the fact that some are set for all architectures.

The SMM GNVS pointer is normally updated only when the ACPI tables are created, which does not happen in the resume path. In order to restore this pointer it needs to be available at resume time. The method used to locate it at creation time cannot be used again as that magic signature is overwritten with the address itself. So a new CBMEM ID is added to store the 32bit address so it can be found again easily. A new function is defined to save this pointer in CBMEM which needs to be called when the ACPI tables are created in each mainboard when write_acpi_tables() is called. The cpu_index variable had to be renamed due to a conflict when cpu/cpu.h is added for the smm_setup_structures() prototype.

2012-11-12cbfstool: Rework to use getopt style parametersStefan Reinauer
- Adding more and more optional and non-optional parameters bloated cbfstool and made the code hard to read with a lot of parsing in the actual cbfs handling functions. This change switches over to use getopt style options for everything but command and cbfs file name. - This allows us to simplify the coreboot Makefiles a bit - Also, add guards to include files - Fix some 80+ character lines - Add more detailed error reporting - Free memory we're allocating Signed-off-by: Stefan Reinauer <reinauer@google.com> Change-Id: Ia9137942deb8d26bbb30068e6de72466afe9b0a7 Reviewed-on: http://review.coreboot.org/1800 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

Some of the modules use their own rolled pci_or_configX functions. Therefore, make them first class so everyone can use them without copying them.

Double equal sign like "test a == b" works. It really does, except NetBSD. But I haven't found any clue in the manual for the command test about "==".

2012-11-12Reduce default stack size to 4KStefan Reinauer
coreboot uses about 2K of stack on the BSP, and about 1K of stack on the APs. No reason to use an overdimensonal stack of 32k per core/thread.

2012-11-12oprom: Ensure that mode information is valid before putting it in the tables.Gabe Black
At least when CONFIG_CHROMEOS is turned on, it's possible for CONFIG_FRAMEBUFFER_KEEP_VESA_MODE to be set but for there not to be any valid information to put into the framebuffer coreboot table. That means that what's put in there is junk, probably all zeroes from the uninitialized global variable the mode information is stored in (mode_info). When a payload uses libpayload and turns on the coreboot framebuffer console, that console will attempt to scroll at some point and decrease the cursor's y coordinate until it is less than the number of rows claimed by the console. The number of rows is computed by taking the vertical resolution of the framebuffer and dividing it by the height of the font. Because the mode information was all zeroes, the coreboot table info is all zeroes, and that means that the number of rows the console claims is zero. You can't get the unsigned y coordinate of the cursor to be less than zero, so libpayload gets stuck in an infinite loop. The solution this change implements is to add a new function, vbe_mode_info_valid, which simply returns whether or not mode_info has anything in it. If not, the framebuffer coreboot table is not created, and libpayload doesn't get stuck.
