* kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/libMasahiro Yamada2014-03-28-44/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.

| | | | | | | | | | | | | | | | | | Some version of Andes core support FPU coprocessor, if this is the case, and toolchain support FPU instruction set, we should enable it at low level initialization time. Signed-off-by: Kuan-Yu Kuo <ken.kuoky@gmail.com> Cc: Macpaul Lin <macpaul@gmail.com>

| * nds32: ag101/ag102: Fix setting lastdec and now valuesAxel Lin2013-07-24-3/+4
| | | | | | | | | | | | | | | | | | | | The timer3 counter unit for lastdesc and now values are inconsistent in current code. The unit of "readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2)" is second. However, CONFIG_SYS_HZ is defined as 1000 in board config file. This means the accuracy of "lastdec" and "now" should be in millisecond, thus fix the equation to set lastdec and now variables accordingly. Signed-off-by: Axel Lin <axel.lin@ingics.com>

| | | | | | | | | | | | | | | | | | The original adp-ag101/adp-ag101p initialize only one bank(64MB) by default at boot time, but it is not enough for some application, so increasing to two banks(128M). Signed-off-by: Kuan-Yu Kuo <ken.kuoky@gmail.com> Cc: Macpaul Lin <macpaul@gmail.com>

* nds32: split common cache access from cpu into libMacpaul Lin2012-07-20-112/+0
| | | | | | | | | | | 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@gmail.com>

* nds32/ag101: cpu and init funcs of SoC ag101Macpaul Lin2011-10-22-0/+792
SoC ag101 is the first chip using NDS32 N1213 cpu core. Add header file of device offset support for SoC ag101. Add main function of SoC ag101 based on NDS32 n1213 core. Add lowlevel_init.S and other periphal related code. This version of lowlevel_init.S also replace hardcode value by MARCO defines from the GPL version andesboot for better code quality.
