Subject: flash: do not fail even if flash_size is zero
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=70879a92561abd300e9e84b25fff841bb3b34837;p=project%2Fbcm63xx%2Fu-boot.git

flash: do not fail even if flash_size is zero

CONFIG_SYS_MAX_FLASH_BANKS_DETECT allows to determine the number of
flash banks at run-time, that is, there is a possibility that no flash
bank is found.  Even in such cases, it makes sense to continue the
boot process without any flash device.
