* OMAP3 SPL: Provide weak omap_rev_stringTom Rini2011-10-27-1/+0
| | | | | | | | | We add an weak version of omap_rev_string in omap-common/spl.c and while at it drop the omap3 version. Move the prototype over to <asm/omap_common.h> with the other SPL functions. Signed-off-by: Tom Rini <trini@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* omap4: make SDRAM init work for ES1.0 siliconAneesh V2011-09-13-3/+2
| | | | | | | | | | | | 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>

* omap: add MMC and FAT support to SPLAneesh V2011-08-03-0/+8
| | | | | | | | | | | | | | - Add MMC raw and FAT mode boot support for OMAP - Provide a means by which parameters passed by ROM-code can be saved in u-boot. - Save boot mode related information passed by OMAP4 ROM-code and use it to determine where to load the u-boot from - Assumes that the image has a mkimage header. Gets the payload size and load address from this header. If the header is not detected assume u-boot.bin as payload Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* omap: add basic SPL supportAneesh V2011-08-03-0/+1
| | | | | | | | | | | | | - Provide alternate implementations of board_init_f() board_init_r() for OMAP spl. - Provide linker script - Initialize global data - Add serial console support - Update CONFIG_SYS_TEXT_BASE to allow for SPL's bss and move it to board config header from config.mk Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* omap4: calculate EMIF register valuesAneesh V2011-08-03-6/+14
| | | | | | | | | | | | | | 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.

* omap4: cleanup pin mux dataAneesh V2011-08-03-1/+3
| | | | | | | | | | | | | - separate mux settings into essential and non essential parts - essential part is board independent as of now(so move it to SoC directory). Will help in having single SPL for all boards. - Non-essential part(the pins not essential for u-boot to function) need to be phased out eventually. - Correct mux data by aligning to the latest settings in x-loader Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* omap4: utility function to identify the context of hw initAneesh V2011-08-03-1/+48
| | | | | | | | | | | | | | | | 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. Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* ARMV7: OMAP: Add new mmc driver compatible with CONFIG_GENERIC_MMCSukumar Ghorai2010-10-17-0/+10
| | | | | | | | | | | | | OMAP boards currently use a legacy mmc driver. This patch adds a new mmc driver which will work with the generic mmc driver in u-boot. This new driver will work with both OMAP3 and OMAP4 boards. This patch does not remove the old driver. It should remain in the tree until all boards that use it switch to the new driver.
