For arm/snow, current bootblock is larger than previously assigned CBFS offset
and will fail to boot. To prevent this happening again in future, cbfstool now
checks if CBFS will overlap bootblock.
A sample error message:
E: Bootblock (0x0+0x71d4) overlap CBFS data (0x5000)
E: Failed to create build/coreboot.pre1.tmp.
arm/snow offset is also enlarged and moved to Kconfig variable.

The "add" command is compatible with all legacy usage. Also, to support
platforms without top-aligned address, all address-type params (-b, -H, -l) can
now be ROM offset (address < 0x8000000) or x86 top-aligned address (address >
0x80000000).
Example:
cbfstool coreboot.rom add -f config -n config -t raw -b 0x2000
cbfstool coreboot.rom add -f stage -n newstage -b 0xffffd1c0
Verified boot-able on both ARM(snow) and x86(QEMU) system.

Usage Changes: To support platforms with different memory layout, "create" takes
two extra optional parameters:
"-b": base address (or offset) for bootblock. When omitted, put bootblock in
end of ROM (x86 style).
"-H": header offset. When omitted, put header right before bootblock,
and update a top-aligned virtual address reference in end of ROM.
Example: (can be found in ARM MAkefile):
cbfstool coreboot.rom create -m armv7 -s 4096K -B bootblock.bin \
-a 64 -b 0x0000 -H 0x2040 -o 0x5000
Verified to boot on ARM (Snow) and X86 (QEMU).

To support platforms without top-aligned address mapping like ARM, "locate"
command now outputs platform independent ROM offset by default. To retrieve x86
style top-aligned virtual address, add "-T".
To test:
cbfstool coreboot.rom locate -f stage -n stage -a 0x100000 -T
# Example output: 0xffffdc10

Old cbfstool may produce CBFS image with calculation error in size of last empty
entry, and then corrupts master header data when you really use every bit in
last entry. This fix will correct free space size when you load ROM images with
cbfs_image_from_file.

Current cbfstool implementation is relying on global variables to pass processed
data, and the calculation of address is based on x86 architecture (ex, always
assuming 0x0000 as invalid address), not easy to be used on platforms without
top-aligned memory mapping. This CL is a first step to start a new cbfstool
without global variables, and to prevent assuming memory layout in x86 mode.
The first published APIs are for reading and writing existing CBFS ROM image
files (and to find file entries in a ROM file).
Read cbfs_image.h for detail usage of each API function.
