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 is depedent on the following series: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/95550
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 * Determination of u-boot size to avoid reading extra content while loading U-Boot * Modular apporach to enable future addition of support for all OMAP3/4 platforms
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
