Subject: altera_qspi: set fail_addr for erase ops
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a1b1d7eceb033c256ae661d65732323809fb9101;p=u-boot.git

altera_qspi: set fail_addr for erase ops

If the erase fails, fail_addr might indicate exactly which block
failed. If fail_addr = MTD_FAIL_ADDR_UNKNOWN, the failure was not
at the device level or was not specific to any particular block.
