This series adds mmc SPL support for OMAP4. This is essentially an up-streaming effort for TI's x-loader for OMAP4 using the SPL framework
This work partly draws upon previous work done for x-loader by: Santosh Shilimkar santosh.shilimkar@ti.com Rajendra Nayak rnayak@ti.com and many others
This series depends on the following series for the new SPL framework: http://marc.info/?l=u-boot&m=131056990001719&w=2
Features supported: * Clock init - DPLL locking, clock domains/modules enabling * SDRAM/DMM initialization * Mux initialization * MMC raw read support * MMC FAT read support
Improvments over x-loader: * Code completely revamped * DPLL programming that works for all SYS_CLK frequencies * Automatic SDRAM identification and initialization * Board dependent parts(especially mux) deferred to u-boot. So, same SPL will work for Panda and SDP and most likely on any other board that comes along * Flexible about the payload. Any image with a mkimage header can be loaded. * The core SPL logic is generic and available for OMAP3/4. So, OMAP3 platforms can easily extend this work to add SPL support for the respective boards.
V2: * Some fixes in SDRAM init, clock init * Use of pre-calculated M & N values for DPLL locking instead run-time calculation * Change in make files to allow reuse of common rules between boards * Console initialization moved further earlier in the boot allowing traces from even clock initialization code * Reuse utility macros from a previous series
V3: * Moved to the new SPL framework * struct based register access for clock init * Squashed together related patches as per Wolfgang's suggestions * Re-organization of code in sdram init for better readability * SPL loading the payload using mkimage header * Avoided using custom bit-field accessor macros * Several other minor changes(documented in respective patches)
