Subject: m68k: Assure end of U-Boot is at 8-byte aligned offset
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9ed99e2eeadb4127b8de2ecbc066de6180394355;p=thirdparty%2Fu-boot.git

m68k: Assure end of U-Boot is at 8-byte aligned offset

Make sure the end of U-Boot is at 8-byte aligned offset, not 4-byte
aligned offset. This allows safely appending DT at the end of U-Boot
with the guarantee that the DT will be at 8-byte aligned offset. This
8-byte alignment is now checked by newer libfdt 1.7.2 .
