Revert "Merge patch series "vbe: Series part E""

2024-12-13T03:07:26+00:00

This reverts commit 1fdf53ace13f745fe8ad4d2d4e79eed98088d555, reversing
changes made to e5aef1bbf11412eebd4c242b46adff5301353c30.

I had missed that this caused too much size growth on rcar3_salvator-x.

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.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

include/u-boot/crc.h: pull 'uint' definition on musl targets

2020-01-03T14:47:10+00:00

The build failure was originally reported on arm64-musl
target at https://bugs.gentoo.org/703132. Here is the amd64-musl
variant:

```
$ LANG=C make CROSS_COMPILE=x86_64-gentoo-linux-musl- tools-only_defconfig -j$(nproc)
$ LANG=C make CROSS_COMPILE=x86_64-gentoo-linux-musl- tools-all            -j$(nproc)
...
include/u-boot/crc.h:37:44: error: unknown type name 'uint'; did you mean 'int'?
   37 | void crc16_ccitt_wd_buf(const uint8_t *in, uint len,
      |                                            ^~~~
      |                                            int
```

Note: 'uint' is not defined there.

On glibc 'uint' comes from  and happens to work on most .c files.

The change imports 'uint' declaration from ''.

crc: Fix code style with crc functions

2019-12-02T23:23:07+00:00

Some of these have a space before the bracket. Drop it to fix the style.
Add some missing function comments while here.

Note that u32 and u8 cannot be used here since crc.h is included on the
host side.

common: Drop linux/crc8.h

2019-12-02T23:23:07+00:00

We have an existing U-Boot header for the one function that this defines.
Use that instead of the linux/ one. Move over the nice comment.

Roll CRC16-CCITT into the hash infrastructure

2018-12-09T01:18:44+00:00

The CRC16-CCITT checksum function is useful for space-constrained
applications (such as obtaining a checksum across a 2KBit or 4KBit
EEPROM) in boot applications. It has not been accessible from boot
scripts until now (due to not having a dedicated command and not being
supported by the hash infrstructure) limiting its applicability
outside of custom commands.

This adds the CRC16-CCITT (poly 0x1021, init 0x0) algorithm to the
list of available hashes and adds a new crc16_ccitt_wd_buf() to make
this possible.
