There are some CFI chips which require non standard procedures to get into QRY mode. The possible way to support them would be trying different modes till QRY will be read. This patch introduce two new functions qry_mode_on qry_mode_off. qry_mode_on tries different commands in order switch chip into QRY mode. So if we have one more "odd" chip - we just could add several lines to qry_mode_on. Also using these functions remove unnecessary code duplicaton in porbe procedure. Currently there are two "odd" cases 1. Some old intel chips which require 0xFF before 0x98 2. ST M29DW chip which requires 0x98 to be sent at 0x555 (according to CFI should be 0x55) This patch is partialy based on the patch from Uwe (see "[PATCH 2/4] [RFC][MTD] cfi_probe: remove Intel chip workaround" thread ) Signed-off-by: Alexey Korolev <akorolev@infradead.org> Signed-off-by: Alexander Belyakov <abelyako@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> |
