From 516793c61b3db1f60e0b0d0e3c382bcca9ae84fd Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 17 May 2007 10:19:23 +0100 Subject: [ARM] ARMv6: add CPU_HAS_ASID configuration Presently, we check for the minimum ARM architecture that we're building for to determine whether we need ASID support. This is wrong - if we're going to support a range of CPUs which include ARMv6 or higher, we need the ASID. Convert the checks to use a new configuration symbol, and arrange for ARMv6 and higher CPU entries to select it.
