Author: stefanct Date: Sun Jun 1 04:21:02 2014 New Revision: 1808 URL: http://flashrom.org/trac/flashrom/changeset/1808
Log: Combine block_erase*_en29lv640b and block_erase*_m29f400bt respectively. This patch combines two identical block and chip erase functions respectively: - Merge block_erase_m29f400bt and block_erase_en29lv640b into erase_block_shifted_jedec. - Merge block_erase_chip_m29f400bt and block_erase_chip_en29lv640b into erase_chip_block_shifted_jedec. Leave their implementations in en29lv640b.c for now.
