From 81317960466ebd37fd958aa07993e3fea461dbe4 Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Wed, 27 Jan 2010 16:57:07 +0900 Subject: [PATCH] ARM: S5P6440: Move common memory map definitions for S5P 1. Moved common memory map definitions for S5P such as S5P_VA_XXX into plat-s5p/include/mach/map-s5p.h from mach-s5p6440/include/mach. 2. Removed unnecessary definitions in the map.h and irq.c 3. Removed the unnecessary support for unaligned UART address 4. Renamed S5P_VA_VICx definitions as VA_VICx 5. Moved the definitons of VIC_BASE to plat-s5p/include/plat/irqs.h Signed-off-by: Kukjin Kim Signed-off-by: Ben Dooks --- .../mach-s5p6440/include/mach/debug-macro.S | 4 +- arch/arm/mach-s5p6440/include/mach/map.h | 65 ++++--------------- .../mach-s5p6440/include/mach/regs-clock.h | 2 +- arch/arm/mach-s5p6440/include/mach/tick.h | 2 +- arch/arm/mach-s5p6440/mach-smdk6440.c | 4 +- arch/arm/plat-s5p/cpu.c | 19 +++--- arch/arm/plat-s5p/include/plat/irqs.h | 2 + arch/arm/plat-s5p/include/plat/map-s5p.h | 32 +++++++++ arch/arm/plat-s5p/irq.c | 5 +- 9 files changed, 65 insertions(+), 70 deletions(-) create mode 100644 arch/arm/plat-s5p/include/plat/map-s5p.h diff --git a/arch/arm/mach-s5p6440/include/mach/debug-macro.S b/arch/arm/mach-s5p6440/include/mach/debug-macro.S index f3a5d1635be5..48cdb0da026c 100644 --- a/arch/arm/mach-s5p6440/include/mach/debug-macro.S +++ b/arch/arm/mach-s5p6440/include/mach/debug-macro.S @@ -22,8 +22,8 @@ .macro addruart, rx mrc p15, 0, \rx, c1, c0 tst \rx, #1 -
