[U-Boot] [PATCH v2 00/22] U-Boot MMC SPL for OMAP4

[Aneesh V]

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 at ti.com>
	Rajendra Nayak <rnayak at 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
