option CONFIG_COMPRESSED_PAYLOAD_LZMA=1
option CONFIG_PRECOMPRESSED_PAYLOAD=1
set in Config.lb but accidentally use an uncompressed payload, coreboot (v2)
bombs out like this:
elfboot: Attempting to load payload.
rom_stream: 0xfffc0000 - 0xfffdefff
Uncompressing to RAM 0x01000000 Decoder scratchpad too small!
Decoding error = 1
Unexpected Exception: 6 @ 10:04000408 - Halting
Code: 0 eflags: 00010057
eax: 00000101 ebx: 04000400 ecx: 000003d4 edx: fffc0000

The attached patch modifies v2's lzma code so that it assumes an uncompressed
payload if it fails to find a properly compressed payload.
Compare with the fatal error above:
elfboot: Attempting to load payload.
rom_stream: 0xfffc0000 - 0xfffdefff
Uncompressing to RAM 0x01000000 Decoder scratchpad too small!
olen = 0x00000000 done.
Decompression failed. Assuming payload is uncompressed...
Found ELF candidate at offset 0
header_offset is 0
Try to load at offset 0x0
If you don't have CONFIG_COMPRESSED_PAYLOAD_LZMA and
CONFIG_PRECOMPRESSED_PAYLOAD set and use an uncompressed payload, things are as
before:
elfboot: Attempting to load payload.
rom_stream: 0xfffc0000 - 0xfffdefff
Found ELF candidate at offset 0
header_offset is 0
Try to load at offset 0x0
One can argue that this is a case of 'builder beware', but my counter argument
is that anything that causes unexpected runtime breakage is really, really,
really bad, and should be avoided where possible.
This patch also fixes one erroneous comment.
