including the AMD Am29LV320.
-config MTD_CFI_AMDSTD_RETRY
- int "Retry failed commands (erase/program)"
- depends on MTD_CFI_AMDSTD
- default "0"
- help
- Some chips, when attached to a shared bus, don't properly filter
- bus traffic that is destined to other devices. This broken
- behavior causes erase and program sequences to be aborted when
- the sequences are mixed with traffic for other devices.
-
- SST49LF040 (and related) chips are know to be broken.

-config MTD_CFI_AMDSTD_RETRY_MAX
- int "Max retries of failed commands (erase/program)"
- depends on MTD_CFI_AMDSTD_RETRY
- default "0"
- help
- If you have an SST49LF040 (or related chip) then this value should
- be set to at least 1. This can also be adjusted at driver load
- time with the retry_cmd_max module parameter.
