• 51c2345bd   Roll CRC16-CCITT into the hash infrastructure ... Browse Code »

  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.

• a740ee913   lib: merge CRC16-CCITT into u-boot/crc.h ... Browse Code »

  This merges the CRC16-CCITT headers into u-boot/crc.h to prepare for
  rolling CRC16 into the hash infrastructure. Given that CRC8, CRC32
  and CRC32-C already have their prototypes in a single header file, it
  seems a good idea to also include CRC16-CCITT in the same.

• 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »

  56

  When U-Boot started using SPDX tags we were among the early adopters and
  there weren't a lot of other examples to borrow from. So we picked the
  area of the file that usually had a full license text and replaced it
  with an appropriate SPDX-License-Identifier: entry. Since then, the
  Linux Kernel has adopted SPDX tags and they place it as the very first
  line in a file (except where shebangs are used, then it's second line)
  and with slightly different comment styles than us.

  In part due to community overlap, in part due to better tag visibility
  and in part for other minor reasons, switch over to that style.

  This commit changes all instances where we have a single declared
  license in the tag as both the before and after are identical in tag
  contents. There's also a few places where I found we did not have a tag
  and have introduced one.

• ecb57f69b   lib/crc16.c: Rename cyg_crc16() to crc16_ccitt() and add crc start value ... Browse Code »

  The original name of this function is unclear. This patch renames this
  CRC16 function to crc16_ccitt() matching its name with its
  implementation.

  To make the usage of this function more flexible, lets add the CRC start
  value as parameter to this function. This way it can be used by other
  functions requiring different start values than 0 as well.

• 78acc472d   Rename lib_generic/ to lib/ ... Browse Code »

  Now that the other architecture-specific lib directories have been
  moved out of the top-level directory there's not much reason to have the
  '_generic' suffix on the common lib directory.
