Subject: SBC8548: fix address mask to allow 64M flash
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ccf1ad535ae1c0dc2d466235c668adbdfe3a55b7;p=u-boot.git

SBC8548: fix address mask to allow 64M flash

Fix incorrect mask to enable all 64MB of onboard flash.
Previously U-Boot incorrectly mapped only 8MB of flash, this
patch correctly maps all the available flash.
