From c7fb2ae67b0dc3c2c38f8ef630a3a72374440032 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Thu, 28 Jun 2012 21:26:41 +0300 Subject: Intel cpus: use CPU_ADDR_BITS from Kconfig during CAR MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Default CPU_ADDR_BITS is 36. For Atom (model_106cx) use 32. This model is known to fail execution-in-place (XIP) with the default 36. Pentium M should use 32, but doesn't even with this patch. Some Xeon and CORE(2) models should use 38 or 40.
