Subject: armv8: fsl-layerscape: make icid setup endianness aware
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=aef654a2ed386d8bd53053383f6bf15ba016a79c;p=u-boot.git

armv8: fsl-layerscape: make icid setup endianness aware

The current implementation assumes that the registers holding the ICIDs
are universally big endian. That's no longer the case on newer
platforms so update the code to take into account the endianness of
each register.
