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.shilim...@ti.com>
Rajendra Nayak <rna...@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)
V4:
* Changed the CONFIG_SYS_SPL_* config flags to CONFIG_SPL_*
* Changed the name omap4_rev_string used in spl.c as this
file is common for OMAP3/4
