mtd: cfi_cmdset_0002: add 0xFF intolerance for M29W128G

2009-10-05T16:31:52+00:00

commit 23af51ecfb04ff65bae51bd8e2270f4449abc789 upstream. The M29W128G Numonyx flash devices are intolerant to any 0xFF command: in the Cfi_util.c the function cfi_qry_mode_off() (that resets the device after the autoselect mode) must have a 0xF0 command after the 0xFF command. This fix solves also the cause of the fixup_M29W128G_write_buffer() fix, that can be removed now. The following patch applies to 2.6.30 kernel.

2009-03-20T18:32:17+00:00

If the inval_cache_and_wait_for_operation() is re-entered by write operation when erase operation is in progress, the chip->erase_suspended will be cleared, this cause the erase timeo is not reset and will result time out error for erase. Signed-off-by: Graff Yang Signed-off-by: David Woodhouse
