Subject: Fix off-by-one error in passing initrd end address via device tree
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ce6b27a874fe30e7126ae93c060277770ee85ced;p=u-boot.git

Fix off-by-one error in passing initrd end address via device tree

The initrd_end variable contains the address immediately *after* the
initrd blob, not the last address containing data.  This patch fixes
an inadvertent off-by-one when setting up the initrd reserved map.
