Subject: mxs: mxsboot: fix endianess for sd boot images
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=b5e7586a73d4eb7b0aa9c597f293a584a2a1800a;p=u-boot.git

mxs: mxsboot: fix endianess for sd boot images

Running mxsboot on a big-endian system produces a sd image which
cannot be started by the i.MX28 ROM. It complains on the debug
uart as following:
0x8020a009
          0x80502008
0x8020a009
          0x80502008
...

Enforcing all fields within the BCB to little-endian make
the image bootable again.
