From: Tom Rini Date: Sat, 5 Mar 2016 19:07:44 +0000 (-0500) Subject: sandbox: Fix building with LLVM X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=699946ae61d52547113ccfc5bdca116d4ade3c6f;p=u-boot.git sandbox: Fix building with LLVM - The macro __BIGGEST_ALIGNMENT__ is gcc-specific. If it is not defined we'll just assume 16. This is correct for at least the common cases and LLVM does not provide an equivalent macro. - When linking U-Boot we're passing -T to the linker, and while gcc will just pass this along with LLVM we need to be specific.
