From 867e359b97c970a60626d5d76bbe2a8fadbf38fb Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Fri, 28 May 2010 23:09:12 -0400 Subject: arch/tile: core support for Tilera 32-bit chips. This change is the core kernel support for TILEPro and TILE64 chips. No driver support (except the console driver) is included yet. This includes the relevant Linux headers in asm/; the low-level low-level "Tile architecture" headers in arch/, which are shared with the hypervisor, etc., and are build-system agnostic; and the relevant hypervisor headers in hv/.
