From b745e82837e7c285fefdecfd580a343ecbd3baff Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Wed, 16 Mar 2016 19:55:55 -0400 Subject: arm: clang: Update support slightly - Move most of the flags required into LLVM_RELFLAGS to test at build time instead of requiring them to be passed in. - Update doc/README.clang to reflect this - Switch to rpi_2 as the example as it's closer to working out of the box than rpi is.
