* OMAP3: Change mem_ok to clear again after reading backTom Rini2011-12-06-0/+1
| | | | | | | | It's possible to need to call this function on the same banks multiple times so we want to be sure that 'pos A' is cleared out again at the end. Signed-off-by: Tom Rini <trini@ti.com>
* OMAP3: Add a helper function to set timings in SDRCTom Rini2011-12-06-55/+61
| | | | | | | | Since we go through the sequence to setup the SDRC timings more than once, break this logic out into its own function and have that function call mem_ok() to make sure the memory is usable. Signed-off-by: Tom Rini <trini@ti.com>
* OMAP3: Update SDRC dram_init to always call make_cs1_contiguous()Tom Rini2011-12-06-12/+11
| | | | | | | | | | | | | We update the comment in make_cs1_contiguous() to be a little bit more clear (it's been copy/pasted from other silicons) and then explain in dram_init() why we need to always try this. Note that in the previous behavior we were always calling this on boards that never had cs1 populated anyhow so making sure we do this always is fine and will correct things like omap3evm detecting an invalid amount of memory (384MB).

* arm, da850: Add pinmux configurations to the arch treeChristian Riesch2011-12-06-0/+167
| | | | | | | | | | | | | Up to now nearly every davinci board has separate code for the definition of pinmux configurations.

| | | | | | | | | | | TPS power IC is controlled using a GPIO (gpio_wk7). This GPIO should be maintained at logic 1 always. As such an internal pull-up on this pin will do the job, driving the GPIO outuput is not needed. This will avoid the need of using GPIO library in SPL and also may save some power.

* armv7: disable L2 cache in cleanup_before_linux()Aneesh V2011-12-06-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | We were not disabling external caches before jumping to kernel. We were flushing all caches including external caches and disabling caches globally in CP15 System Control register. Apparently this is not enough. The bootstrap loader in Linux kernel that does decompression enables data-caches again, flush them after use and disable them before jumping to kernel proper. However, it's not aware of the external caches. Since we have left external cache enabled, external cache will get used once caches are enabled globally, but it's not flushed because decompressor is not aware of external caches. When it jumps to kernel with caches disabled globally, we have stale data in the external cache and a coherency problem. This was breaking the boot for OMAP4 with latest mainline kernel. The solution is to disable external caches in cleanup_before_linux(). With this fix kernel is booting again. Cc: Albert Aribaud <albert.u.boot@aribaud.net> Signed-off-by: Aneesh V <aneesh@ti.com>

* | omap4/5: Add support for booting with CH.Sricharan2011-11-15-41/+164
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Configuration header(CH) is 512 byte header attached to an OMAP boot image that will help ROM code to initialize clocks, SDRAM etc and copy U-Boot directly into SDRAM. CH can help us in by-passing SPL and directly boot U-boot, hence it's an alternative for SPL. However, we intend to support both CH and SPL for OMAP4/5. Initialization done through CH is limited and is not equivalent to that done by SPL. So U-Boot has to distinguish between the two cases and handle them accordingly. This patch takes care of doing this. Signed-off-by: sricharan <r.sricharan@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency. Also moved some part of code from the basic platform support that can be made common for OMAP4/5. Rest is kept out seperately.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
