d506719f7f omap4: support TPS programming
TPS62361 is the new power supply used in OMAP4460 that
supplies vdd_mpu.

VCORE1 from Phoenix supplies vdd_core and VCORE2 supplies
vdd_iva. VCORE3 is not used in OMAP4460.

8cf686e19b omap: add MMC and FAT support to SPL
- 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

095aea293b omap4: calculate EMIF register values
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.

469ec1e353 omap4: cleanup pin mux data
- 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

d2f18c275e omap4: utility function to identify the context of hw init
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.

The function davinci_emac_mii_mode_sel() is defined in
board/davinci/common/misc.c for any DA8xx CPU which has
CONFIG_DRIVER_TI_EMAC enabled. However, the prototype was only being

This patch declares it for all DA8xx CPUs where CONFIG_DRIVER_TI_EMAC
is enabled.

2c451f7831 armv7: cache maintenance operations for armv7
- Add a framework for layered cache maintenance
	- separate out SOC specific outer cache maintenance from
	  maintenance of caches known to CPU

- Add generic ARMv7 cache maintenance operations that affect all
  caches known to ARMv7 CPUs. For instance in Cortex-A8 these
  opertions will affect both L1 and L2 caches. In Cortex-A9
  these will affect only L1 cache

- D-cache operations supported:
	- Invalidate entire D-cache
	- Invalidate D-cache range
	- Flush(clean & invalidate) entire D-cache
	- Flush D-cache range
- I-cache operations supported:
	- Invalidate entire I-cache

- Add maintenance functions for TLB, branch predictor array etc.

- Enable -march=armv7-a so that armv7 assembly instructions can be
  used
