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>
2011-11-15omap5: emif: Add emif/ddr configurations required for omap5 evmSricharan
Add the emif configurations required for omap5 soc.Add the correct ddr part configurations required for omap5 evm board. EDB8164B3PH from ELPIDA is the part used on the board. Also changes are done to retain some part of the code common for OMAP4/5 and keep only the remaining in the Soc specific directories.

2011-11-15omap5: Add minimal support for omap5430.Sricharan
This patch adds the minimal support for OMAP5. The platform and machine specific headers and sources updated for OMAP5430. 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. The same approach is followed for clocks and emif support in the subsequent patches.

2011-09-13omap4: make SDRAM init work for ES1.0 siliconAneesh V
SDRAM init was not working on ES1.0 due to a programming error. A pointer that was passed by value to a function was set in function emif_get_device_details(), but the effect wouldn't be seen in the calling function. The issue came out while testing for ES1.0 because ES1.0 doesn't have any SDRAM chips connected to CS1 Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

2011-08-03omap4: calculate EMIF register valuesAneesh V
Calculate EMIF register values based on AC timing parameters from the SDRAM datasheet and the DDR frequency rather than using the hard-coded values. For a new board the user doen't have to go through the tedious process of calculating the register values. Instead, just provide the AC timings from the device data sheet as input and the driver will automatically calculate the register values.

2011-08-03omap4: utility function to identify the context of hw initAneesh V
The basic hardware init of OMAP4(s_init()) can happen in 4 different contexts: 1. SPL running from SRAM 2. U-Boot running from FLASH 3. Non-XIP U-Boot loaded to SDRAM by SPL 4. Non-XIP U-Boot loaded to SDRAM by ROM code using the Configuration Header feature What level of hw initialization gets done depends on this context. Add a utility function to find this context.

2010-10-17ARMV7: OMAP: Add new mmc driver compatible with CONFIG_GENERIC_MMCSukumar Ghorai
