From c94e4ad2d5e0e5f4036cccaa0e6e773841e8f859 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 19 Aug 2016 16:24:36 +0100 Subject: ARM: document and update UNCACHEABLE_ADDR definitions Document the UNCACHEABLE_ADDR definitions for footbridge and SA1100 so that we know where they're located and/or what they're accessing. Change RiscPC to calculate the UNCACHEABLE_ADDR value from FLUSH_BASE as that's where we locate that. UNCACHEABLE_ADDR is used to perform an uncached access (ARMv4 terminology) necessary to force a CPU clock-switch to the memory- speed clock, as required for entering WFI.
