From: Ben Dooks <ben.dooks@codethink.co.uk> The exynos low-level debug macros need to be fixed if the system is being built big endian. Add the necessary endian swaps for accessing the registers to get output working again Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> --- arch/arm/include/debug/samsung.S | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/arch/arm/include/debug/samsung.S b/arch/arm/include/debug/samsung.S index 8d8d922..f4eeed2 100644 --- a/arch/arm/include/debug/samsung.S +++ b/arch/arm/include/debug/samsung.S @@ -15,11 +15,13 @@ .macro fifo_level_s5pv210 rd, rx ldr \rd, [\rx, # S3C2410_UFSTAT] +ARM_BE8(rev \rd, \rd) and \rd, \rd, #S5PV210_UFSTAT_TXMASK .endm .macro fifo_full_s5pv210 rd, rx ldr \rd, [\rx, # S3C2410_UFSTAT] +ARM_BE8(rev \rd, \rd) tst \rd, #S5PV210_UFSTAT_TXFULL .endm @@ -28,6 +30,7 @@ .macro fifo_level_s3c2440 rd, rx ldr \rd, [\rx, # S3C2410_UFSTAT] +ARM_BE8(rev \rd, \rd) and \rd, \rd, #S3C2440_UFSTAT_TXMASK .endm @@ -37,6 +40,7 @@ .macro fifo_full_s3c2440 rd, rx ldr \rd, [\rx, # S3C2410_UFSTAT] +ARM_BE8(rev \rd, \rd) tst \rd, #S3C2440_UFSTAT_TXFULL .endm @@ -50,6 +54,7 @@ .macro busyuart, rd, rx ldr \rd, [\rx, # S3C2410_UFCON] +ARM_BE8(rev \rd, \rd) tst \rd, #S3C2410_UFCON_FIFOMODE @ fifo enabled? beq 1001f @ @ FIFO enabled... @@ -61,6 +66,7 @@ 1001: @ busy waiting for non fifo ldr \rd, [\rx, # S3C2410_UTRSTAT] +ARM_BE8(rev \rd, \rd) tst \rd, #S3C2410_UTRSTAT_TXFE beq 1001b @@ -69,6 +75,7 @@ .macro waituart,rd,rx ldr \rd, [\rx, # S3C2410_UFCON] +ARM_BE8(rev \rd, \rd) tst \rd, #S3C2410_UFCON_FIFOMODE @ fifo enabled? beq 1001f @ @ FIFO enabled... @@ -80,6 +87,7 @@ 1001: @ idle waiting for non fifo ldr \rd, [\rx, # S3C2410_UTRSTAT] +ARM_BE8(rev \rd, \rd) tst \rd, #S3C2410_UTRSTAT_TXFE beq 1001b -- 2.8.3
