* m28evk: Turn on cachesFabio Estevam2012-09-01-2/+0
| | | | | | Turn on data and instruction caches. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* ARM: Remove unused stack and irq config definesRob Herring2012-09-01-1/+0
| | | | | | | | | | | CONFIG_STACKSIZE is not referenced anywhere except on AVR32, but present in most ARM board config files. IRQs are only enabled for 1 config, so remove the unused config options for IRQ and FIQ stack size as well.

* mxs: reorganize source directory for easy sharing of code in i.MXS SoCsOtavio Salvador2012-09-01-2/+2
| | | | | | | | | Most code can be shared between i.MX23 and i.MX28 as both are from i.MXS family; this source directory structure makes easy to share code among them. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Acked-by: Stefano Babic <sbabic@denx.de>

* ARM: mx28: Remove CONFIG_ARCH_CPU_INITFabio Estevam2012-07-07-1/+0
| | | | | | | | | No need to define CONFIG_ARCH_CPU_INIT. All mx28 based boards should use arch_cpu_init(). Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Marek Vasut <marex@denx.de>

* hush.c: Move default CONFIG_SYS_PROMPT_HUSH_PS2 to hush.cTom Rini2012-06-20-1/+0
| | | | | | | | | | Exactly one board has defined CONFIG_SYS_PROMPT_HUSH_PS2 to a value different than "> " which is vision2. I have Cc'd the maintainer here as I strongly suspect this is a bug rather than intentional behavior.

* CONFIG_SYS_BAUDRATE_TABLE: Add <config_fallbacks.h>, place thereTom Rini2012-06-20-1/+0
| | | | | | | | | We provide a default table of { 9600, 19200, 38400, 57600, 115200 } in <config_fallbacks.h> which mkconfig places after <configs/...h> in the generated config file. This is used when a board has not set its own table. Signed-off-by: Tom Rini <trini@ti.com>

* i.MX28: Fix initial stack pointer positionMarek Vasut2012-04-16-1/+1
| | | | | | | | | | | | | | | | | | | The patch: m28evk: Use GENERATED_GBL_DATA_SIZE commit 1084606c972ea5f1d89f69bdbd978b867d0ee521 introduced usage of GENERATED_GBL_DATA_SIZE and calculation of initial stack pointer position defived from that. Due to a small typo, the SP position moved to 0x21f80, which is past the SRAM area. This didn't manifest on the real hardware as the SRAM repeats there (address bits in the CPU being ignored). Though this was caught in QEMU, where it crashed the emulator.

* M28: Cleanup memsize.o OOT buildMarek Vasut2011-12-09-0/+2
| | | | | | | | | | | | | | | | The current way memsize.c is built just made a symlink into the directory with SPL and then compiled it like any other file there. This was bad as that broke the out-of-tree build. The new way introduced in this patch uses the standard spl/Makefile methods (CONFIG_SPL_LIBCOMMON_SUPPORT / CONFIG_SPL_LIBGENERIC_SUPPORT) to let files in common/ be built. Because common/Makefile says memsize.c is always built (SPL and non-SPL build), this fixes our issue with memsize.c out-of-tree build.

* M28: Add memory detection into SPLMarek Vasut2011-11-11-1/+1
| | | | | | | | | | This code allows the DDR DRAM size to be detected at runtime. The RAM size is stored into two scratch registers, from which it is then fetched in U-Boot.

* iMX28: Fix ARM vector handlingMarek Vasut2011-11-11-0/+1
| | | | | | | | | | | | | | | This patch introduces proper ARM vector handling for i.MX28 CPU. This issue wasn't addressed because the interrupts weren't enabled on any ARMv5 core, therefore the issue wasn't noticed earlier. In previous implementation, the vectoring code used by i.MX28 CPU when an exception happened was that of the SPL. With this change, the branch target when an exception happens can be reconfigured by U-Boot.
