Subject: tlv-eeprom: adapt for integration with hvtlv
X-Git-Url: http://gitweb.hugovil.com/?a=commitdiff_plain;h=f10cb09a7b170592a596a82e7961ec729fe7b71a;p=mtlv.git

tlv-eeprom: adapt for integration with hvtlv

Replace calls to i2c_eeprom_read/write and call eeprom_block_read/write
from main.c.

Use zlib crc32 function.
