[U-Boot] [PATCH] nds32: split common cache access from cpu into lib
by Macpaul Lin 20 Jul '12

20 Jul '12

This commit does the following updates. 1. Split the common cache access from cpu.c into lib folder. 2. Rename the following cache api to adapt common.h - dcache_flush_rang -> flush_dcache_rang - icache_inval_range -> invalidate_icache_range 3. Add invalidate_dcache_range Signed-off-by: Macpaul Lin <macpaul(a)gmail.com> --- arch/nds32/cpu/n1213/ag101/cpu.c | 112 ------------------------------ arch/nds32/cpu/n1213/ag102/cpu.c | 112 ------------------------------ arch/nds32/lib/Makefile | 2 +- arch/nds32/lib/cache.c | 145 +++++++++++++++++++++++++++++++++++++++ 4 files changed, 146 insertions(+), 225 deletions(-) create mode 100644 arch/nds32/lib/cache.c diff --git a/arch/nds32/cpu/n1213/ag101/cpu.c b/arch/nds32/cpu/n1213/ag101/cpu.c index c2636b1..a9991e7 100644 --- a/arch/nds32/cpu/n1213/ag101/cpu.c +++ b/arch/nds32/cpu/n1213/ag101/cpu.c @@ -82,115 +82,3 @@ int do_reset(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) /*NOTREACHED*/ } - -static inline unsigned long CACHE_LINE_SIZE(enum cache_t cache) -{ - if (cache == ICACHE) - return 8 << (((GET_ICM_CFG() & ICM_CFG_MSK_ISZ) \ - >> ICM_CFG_OFF_ISZ) - 1);

[U-Boot] [PATCH 1/2] kirkwood: implement kw_sdram_bs_set()
by Gerlando Falauto 20 Jul '12

20 Jul '12

Some boards might be equipped with different SDRAM configurations. When that is the case, CPU CS Window Size Register (CS[0]n Size) should be set to the biggest value through board.cfg file; then its value can be fixed at runtime according to the detected SDRAM size. Therefore, implement kw_sdram_bs_set(), to be called for instance within board_early_init_f().

[U-Boot] I apply to maintain S3C6400 board for u-boot
by Zhong Hongbo 20 Jul '12

20 Jul '12

Hi Denx, I get some information from MAINTAINERS file. I know The board of S3C6400 is a orphaned board. Also I have not the board, But I have a S3C6410 board in my hand. In my development u-boot for my board, I know the S3C6410 replace the s3c6400, and they use the same arm1176 architecture. So I think that I can help do a little thing for S3C6400's u-boot. In the recently, I send the patch serial of S3C6400. This patch is very important for S3C64XX. It clear the old method to operate the I/O port, and adopt the new SPL boot to reduce the code number. I expect get the advice for this patch. But I wait for a long time, I do not know who can help me to review this patch? who can merge this patch? If anyone believe me, I will continue to maintain the board, Maybe I have some limitation, Such as I have a poor english. But I believe I can keep the board can work normal in u-boot mainline, and I will reply the email about S3C64xx CPU in time. What do you think it? Thanks hongbo

Fixed some typos in the i.MX28 PMU code that sets up the VDDD and VDDIO power rails. In addition the VDDD and VDDIO brownout offset values should be divided by a step size before being programmed to the corresponding registers.

[U-Boot] [PATCH] arm: enable unaligned access on ARMv7
by Lucas Stach 20 Jul '12

20 Jul '12

Recent toolchains default to using the hardware feature for unaligned access on ARM v7, rather than doing the software fallback. According to ARM this is safe as all v7 implementations have to support this feature. (http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0471c/BABJFF…) To avoid CPU hangs when doing unaligned memory access, we have to turn off alignment checking in our CPU initialisation code.
