From 221761e0be8fbf5ae5cae827216ae0e92c05c3af Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Thu, 23 Jul 2015 21:08:30 +0200 Subject: README: improve description of compiler requirements People run into "building bootblock without the required toolchain" too often. Update documentation so they don't try to use random compilers to build coreboot.
