Subject: arm: Update our 'ret' assembler macro slightly
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=431afb4ef9fe89e5350b5d497be4c5f8d270393e;p=u-boot.git

arm: Update our 'ret' assembler macro slightly

We only support cores that do Thumb-1 or later.  So we add a comment to
explain this and remove the architecture test.
