crc16: Move standard CRC-16 implementation from ubifs to lib

2022-04-21T18:32:40+00:00

This implementation provides standard CRC-16 algorithm with polynomial
x^16 + x^15 + x^2 + 1.

crc16-ccitt: Rename file with CRC-16-CCITT implementation to crc16-ccitt.c

2022-04-21T18:32:40+00:00

U-Boot CRC-16 implementation uses polynomial x^16 + x^12 + x^5 + 1 which is
not standard CRC-16 algorithm, but it is known as CRC-16-CCITT. Rename file
crc16.c to crc16-ccitt.c to reduce confusion.

acpi: Use finer-grained control of ACPI-table generation

2022-01-25T18:44:36+00:00

Rather than keying everything off ACPIGEN, use the main
GENERATE_ACPI_TABLE option to determine whether the core ACPI code
is included. Make sure these option are not enabled in SPL/TPL since we
never generate tables there.

lib: add BLAKE2 hash support

2022-01-18T13:31:02+00:00

The code is cross-ported from BLAKE2 reference implementation
(https://github.com/BLAKE2/BLAKE2).

With minimal change to remove unused macros/features.

Currently there is only one user inside U-boot (btrfs), and since it
only utilize BLAKE2B, all other favors are all removed.

image: Use the correct checks for CRC32

2021-10-08T19:53:26+00:00

Add a host Kconfig for CRC32. With this we can use CONFIG_IS_ENABLED(CRC32)
directly in the host build, so drop the unnecessary indirection.

Add a few more conditions to SPL_CRC32 to avoid build failures as well as
TPL_CRC32. Also update hash.c to make crc32 optional and to actually take
notice of SPL_CRC32.

Add support for an owned buffer

2021-10-08T19:53:26+00:00

When passing a data buffer back from a function, it is not always clear
who owns the buffer, i.e. who is responsible for freeing the memory used.
An example of this is where multiple files are decompressed from the
firmware image, using a temporary buffer for reading (since the
compressed data has to live somewhere) and producing a temporary or
permanent buffer with the resuilts.

Where the firmware image can be memory-mapped, as on x86, the compressed
data does not need to be buffered, but the complexity of having a buffer
which is either allocated or not, makes the code hard to understand.

Introduce a new 'abuf' which supports simple buffer operations:

- encapsulating a buffer and its size
- either allocated with malloc() or not
- able to be reliably freed if necessary
- able to be converted to an allocated buffer if needed

This simple API makes it easier to deal with allocated and memory-mapped
buffers.
