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.

[PATCH] board_enable selfcheck

by Carl-Daniel Hailfinger

Found this bitrotting away on my disk. Rebased from r1645, last time all snippets compiled was r1539. If you kill the cli_classic.c hunk, it should compile. That hunk was in the patch to make sure the msg_gspew() calls in selfcheck() aren't no-ops by default. Hm. This seems to be a bug still in HEAD. Not for direct merge, there are other random changes in there as well. Stefan, you already wrote a patch doing a board enable array selfcheck, and AFAICS yours checks some more bits. AFAICS the most interesting point in this patch are the verbose messages/comments.

[PATCH] Improve messages on failed erases with default verbosity.

by Stefan Tauner

From: Stefan Tauner <stefan.tauner(a)student.tuwien.ac.at> Without this... Erasing and writing flash chip... ERASE FAILED at 0x00001000! Expected=0xff, Read=0xb4, failed byte count from 0x00000000-0x0000ffff: 0xef09 ERASE FAILED! Reading current flash chip contents... done. <loooooong break while the next eraser and writing is tried> Erase/write done. Verifying flash... VERIFIED. Even if there is not a long temporal pause, it is very confusing for the user to first see a failed erase, followed by a read, a done message and eventually the verification message. This patch inserts "Looking for another erase function." where there is just a silent break above.
