From c514e58cb8eac0d21f4ab5011df75a09eb5edd50 Mon Sep 17 00:00:00 2001 From: Kenneth Tan Date: Sat, 29 Oct 2005 16:32:14 +0100 Subject: [PATCH] [ARM] 3022/1: Missing peripheral devices memory mapping definition for IXP46X processor Patch from Kenneth Tan Defining IXP46X peripheral devices memory mapping definitions that have been missed out: o Peripheral virtual base address is being adjusted to allow more headroom to add extra peripheral device addresses o Peripheral size is being increased to address the above needs o Virtual address of expansion bus and PCI configuration register needs to be adjusted as new peripheral device memory space is overlapping with their virtual address space Signed-off-by: Kenneth Tan Signed-off-by: Deepak Saxena Signed-off-by: Russell King --- include/asm-arm/arch-ixp4xx/ixp4xx-regs.h | 75 +++++++++++++++-------- 1 file changed, 49 insertions(+), 26 deletions(-) diff --git a/include/asm-arm/arch-ixp4xx/ixp4xx-regs.h b/include/asm-arm/arch-ixp4xx/ixp4xx-regs.h index 004696a95bd..2b149ed5914 100644 --- a/include/asm-arm/arch-ixp4xx/ixp4xx-regs.h +++ b/include/asm-arm/arch-ixp4xx/ixp4xx-regs.h @@ -36,11 +36,11 @@ * * 0x6000000 0x00004000 ioremap'd QMgr * -
