Subject: efi_selftest: simplify endian conversion for FDT test
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9abd2ca96ea0e8e68a9ffb5b41d1107ea73ddc0f;p=u-boot.git

efi_selftest: simplify endian conversion for FDT test

UEFI code is always little-endian. Remove a superfluous test.

Remove a superfluous type conversion.
