From 4e6d488af37980d224cbf298224db6173673f362 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 1 Feb 2010 23:26:53 +0100 Subject: ARM: 5910/1: ARM: Add tmp register for addruart and loadsp Otherwise more complicated uart configuration won't be possible. We can use r1 for tmp register for both head.S and debug.S. NOTE: This patch depends on another patch to add the the tmp register into all debug-macro.S files. That can be done with: $ sed -i -e "s/addruart,rx|addruart, rx/addruart, rx, tmp/" arch/arm/*/include/*/debug-macro.S Signed-off-by: Tony Lindgren Signed-off-by: Russell King --- arch/arm/boot/compressed/head.S | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) (limited to 'arch/arm/boot') diff --git a/arch/arm/boot/compressed/head.S b/arch/arm/boot/compressed/head.S index 4fddc509e78e..99b75aa1c2ec 100644 --- a/arch/arm/boot/compressed/head.S +++ b/arch/arm/boot/compressed/head.S @@ -22,13 +22,13 @@ #if defined(CONFIG_DEBUG_ICEDCC) #ifdef CONFIG_CPU_V6 - .macro loadsp, rb + .macro loadsp, rb, tmp .endm .macro writeb, ch, rb mcr p14, 0, \ch, c0, c5, 0 .endm #elif defined(CONFIG_CPU_V7) - .macro loadsp, rb + .macro loadsp, rb, tmp .endm .macro writeb, ch, rb wait: mrc p14, 0, pc, c0, c1, 0 @@ -36,13 +36,13 @@ wait: mrc p14, 0, pc, c0, c1, 0 mcr p14, 0, \ch, c0, c5, 0 .endm #elif defined(CONFIG_CPU_XSCALE) - .macro loadsp, rb + .macro loadsp, rb, tmp .endm .macro writeb, ch, rb mcr p14, 0, \ch, c8, c0, 0 .endm #else - .macro loadsp, rb + .macro loadsp, rb, tmp .endm .macro writeb, ch, rb mcr p14, 0, \ch, c1, c0, 0 @@ -58,7 +58,7 @@ wait: mrc p14, 0, pc, c0, c1, 0 .endm #if defined(CONFIG_ARCH_SA1100) - .macro loadsp, rb + .macro loadsp, rb, tmp mov \rb, #0x80000000 @ physical base address #ifdef CONFIG_DEBUG_LL_SER3 add \rb, \rb, #0x00050000 @ Ser3 @@ -67,13 +67,13 @@ wait: mrc p14, 0, pc, c0, c1, 0 #endif .endm #elif defined(CONFIG_ARCH_S3C2410) - .macro loadsp, rb + .macro loadsp, rb, tmp mov \rb, #0x50000000 add \rb, \rb, #0x4000 * CONFIG_S3C_LOWLEVEL_UART_PORT .endm #else - .macro loadsp, rb - addruart \rb + .macro loadsp, rb, tmp + addruart \rb, \tmp .endm #endif #endif @@ -1025,7 +1025,7 @@ phex: adr r3, phexbuf strb r2, [r3, r1] b 1b -puts: loadsp r3 +puts: loadsp r3, r1 1: ldrb r2, [r0], #1 teq r2, #0 moveq pc, lr @@ -1042,7 +1042,7 @@ puts: loadsp r3 putc: mov r2, r0 mov r0, #0 - loadsp r3 + loadsp r3, r1 b 2b memdump: mov r12, r0 -- cgit v1.2.3
