Michael Hope	bbafc36b1c	lib: add crc7. ... Used as a checksum on command messages when talking with MMC cards. Implemented using the unwound bytewise implementation from https://en.wikipedia.org/wiki/Computation_of_cyclic_redundancy_checks which is a good mix of size and speed. The API and naming matches lib/crc7.c in Linux. Signed-off-by: Michael Hope <mlhx@google.com>	2018-12-30 16:24:10 -05:00
