From d8792a04ca0d8615424f7964155782b1206b5c8d Mon Sep 17 00:00:00 2001 From: Chris Zankel Date: Thu, 15 Nov 2012 03:53:52 +0000 Subject: xtensa: support configurable processor configurations Xtensa is a configurable processor architecture, which allows to define additional instructions and registers. The required variant specific information for the toolchain is delivered in an 'overlay' file, which needs to be 'untarred' to the corresponding directories after the source is installed and patched. This patch provides support for binutils, gcc, and gdb with a very limited changes to the build scripts. These additions are only executed for the Xtensa architecture and have no effect on other architectures. [Thomas: rebased on top of the 'arch: improve definition of gcc mtune, mcpu, etc.' patch, and changed 'Target ABI' to 'Target Architecture Variant'].
