24de357a30 SPL: Add YMODEM over UART load support
Adds support for loading U-Boot from UART using YMODEM protocol.
If YMODEM support is enabled in SPL and the romcode indicates
that SPL loaded via UART then SPL will wait for start of a
YMODEM transfer via the console port.

8a8f084e4f ARM:AM33XX: Add SPL support for AM335X EVM
This patch is added to support SPL feature on AM335X
platform. In this patch, MMC1 is configured as boot
device for SPL and support for other devices will be
added in the next patch series.

ee08a8260a OMAP3: Add SPL_BOARD_INIT hook
Add an SPL_BOARD_INIT hook and for OMAP3 have it turn on i2c.  OMAP4
doesn't need i2c enabled in SPL.  Enable SPL_BOARD_INIT on devkit8000.

78f455c055 omap4/5: Add support for booting with CH.
Configuration header(CH) is 512 byte header attached to an OMAP
boot image that will help ROM code to initialize clocks, SDRAM
etc and copy U-Boot directly into SDRAM. CH can help us in
by-passing SPL and directly boot U-boot, hence it's an alternative
for SPL. However, we intend to support both CH and SPL for OMAP4/5.

Initialization done through CH is limited and is not equivalent
to that done by SPL. So U-Boot has to distinguish between the
two cases and handle them accordingly. This patch takes care
of doing this.

508a58fa8e omap5: Add minimal support for omap5430.
This patch adds the minimal support for OMAP5. The platform and machine
specific headers and sources updated for OMAP5430.

OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture.
It's a dual core SOC with GIC used for interrupt handling and SCU for cache
coherency.

Also moved some part of code from the basic platform support that can be made
common for OMAP4/5. Rest is kept out seperately. The same approach is followed
for clocks and emif support in the subsequent patches.

cc3f705843 OMAP3 SPL: Provide weak omap_rev_string
We add an weak version of omap_rev_string in omap-common/spl.c
and while at it drop the omap3 version.  Move the prototype over
to <asm/omap_common.h> with the other SPL functions.

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

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.
