Subject: tools: relocate-rela: Check that relocation works only for EM_AARCH64
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a1405d9cfedb1228289e617258de3fc0d7facecd;p=u-boot.git

tools: relocate-rela: Check that relocation works only for EM_AARCH64

Relocation support is only for EM_AARCH64 that's why check machine type to
make sure that the code will never run on any unsupported one.
