Subject: crc16-ccitt: Rename file with CRC-16-CCITT implementation to crc16-ccitt.c
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=bb3d71b7eff4f137c1c4560950536aeb1740e004;p=u-boot.git

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

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.
