Currently the HiFive Unleashed produces the following exception:
[DEBUG] Exception: Load address misaligned
[DEBUG] Hart ID: 0
[DEBUG] Previous mode: machine
[DEBUG] Bad instruction pc: 0x080010d0
[DEBUG] Bad address: 0x08026ab3
[DEBUG] Stored ra: 0x080010c8
[DEBUG] Stored sp: 0x08010cc8
The coreboot LZ4 decompression code does some misaligned access during
decompression which the FU540 apparently does not support in SRAM.
Make the compiler generate code that adheres to natural alignment by
fixing the LZ4_readLE16() function and creating LZ4_readLE32().

Order of bits in bitfields is implementation-defined. This makes them
non-portable, especially across systems using different endianness.
This change removes bitfields and uses masking and shifting instead.

Fix two out-of-bounds reads in lz4 decompression:
1) LZ4_decompress_generic could read one byte past the input buffer when
decoding variable length literals due to a missing bounds check. This
issue was resolved in libpayload, commonlib and cbfstool
2) ulz4fn could read up to 4 bytes past the input buffer when reading a
lz4_block_header due to a missing bounds check. This issue was resolved
in libpayload and commonlib.

This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.
Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).
Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.
