2011-12-06OMAP3: Suffix all Micron memory timing parts with their speedTom Rini
Signed-off-by: Tom Rini <trini@ti.com>
2011-12-06OMAP3: Add optimal SDRC autorefresh control valuesTom Rini
This adds the optimal SDRC autorefresh control register values for 100Mhz, 133MHz, 165MHz and 200MHz clocks. We switch to using this to provide the default 165MHz value. Signed-off-by: Tom Rini <trini@ti.com>
2011-12-06omap3: mem: Add MCFG helper macroTom Rini
This adds an MCFG macro to calculate the correct value, similar to the ACTIMA/ACTIMB macros and adds a comment that all of the potential values here are documented in the TRM. Then we convert the Micron value to use this macro. Signed-off-by: Tom Rini <trini@ti.com>
2011-12-06OMAP3: Remove get_mem_type prototypeTom Rini
This function doesn't exist for omap3 Signed-off-by: Tom Rini <trini@ti.com>
2011-12-06OMAP3: Change mem_ok to clear again after reading backTom Rini
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>
2011-12-06OMAP3: Add a helper function to set timings in SDRCTom Rini
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>
2011-12-06OMAP3: Update SDRC dram_init to always call make_cs1_contiguous()Tom Rini
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). Signed-off-by: Tom Rini <trini@ti.com>
2011-12-06omap3: mem: Comment enable_gpmc_cs_config moreTom Rini
Expand the "enable the config" comment to explain what the bit shifts are and define out two of the magic numbers. Signed-off-by: Tom Rini <trini@ti.com>

2011-12-06arm, da850: Add pinmux configurations to the arch treeChristian Riesch

2011-12-06arm926ejs: add noop implementation for dcache opsIlya Yanok
Added noop implementation for dcache operations that will buzz about missing real implementation and disable the dcache. This fixes compilation of DaVinci EMAC driver on arm926ejs. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
2011-12-06davinci_emac: move arch-independent defines to separate headerIlya Yanok
DaVinci EMAC is found not only on DaVinci SoCs but on some OMAP3 SoCs also. This patch moves common defines from arch-davinci/emac_defs.h to drivers/net/davinci_emac.h DaVinci specific PHY drivers hacked to include the new header. We might want to switch to phylib in future.

2011-12-06omap4: emif: fix error in driverAneesh V
There was a typo in the EMIF driver. It went un-noticed because it affected only when automatic detection is enabled and even then half the memory was configured and identified properly. Reported-by: Rockefeller <rockefeller.lin@innocomm.com> Signed-off-by: Aneesh V <aneesh@ti.com>
2011-12-06omap: remove I2C from SPLAneesh V

2011-12-06omap4460: fix TPS initializationAneesh V
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. Signed-off-by: Aneesh V <aneesh@ti.com>

2011-12-06armv7: disable L2 cache in cleanup_before_linux()Aneesh V
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>

2011-11-15omap4/5: Add support for booting with CH.Sricharan
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>
