Hi,
this is v4 of the last part of my recent patchset

[PATCH v3 00/15] Add an SPL to boot the da850evm from SPI
http://lists.denx.de/pipermail/u-boot/2011-November/111182.html

Most of the other parts are already merged, together with
this patchset they introduce an SPL for the da850evm to run
u-boot directly without the need of a UBL (see doc/README.davinci).

The first patches fix dependencies and introduce a function
to load the u-boot image from SPI flash. Patch #4 adds an
SPL to the da850evm configuration. Finally, a simple
AIS (Application Image Script) is required to start the SPL.
This AIS is generated by mkimage. Patch #5 fixes mkimage for building
AIS. Finally the last patch introduces a u-boot.ais target in the
Makefile.

This patchset applies on top of git://git.denx.de/u-boot-ti.git

Changes for v4:
- added documentation for the SPL to doc/README.davinci
- split patchset because it got too big
- use COBJS-$(CONFIG_SPL_SPI_LOAD) instead of ifdefs in
drivers/mtd/spi/Makefile
- use __noreturn instead of __attribute__((noreturn))
- added Acked-by

Changes for v3:
- removed noise and hardcoded values from drivers/mtd/spi/spi_spl_load.c
- replaced $(PAD_TO) in Makefile by $(CONFIG_SPL_MAX_SIZE)

Major changes for v2:
- Added code that actually loads u-boot from SPI flash and starts it.

To build run
make da850evm_config
make u-boot.ais
Then program u-boot.ais to the SPI flash on the da850evm.

Best regards,
Christian
