Subject: malta: store environment in flash
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fba6f45cdcf77985c4bf891322b5442bda1005e0;p=project%2Fbcm63xx%2Fu-boot.git

malta: store environment in flash

Allow the environment to be stored in the monitor flash of a Malta
board. The environment is stored in the final 128KB of the flash, which
both leaves the majority of the flash available for U-boot code and also
matches the location which YAMON uses.
