Hi all,
Heiko Schocher added support for the low level configuration
of the DA850 SoCs and I would like to use this code on my board. At the
same time I would like to add support for this low level configuration
for the da850evm board. This makes it possible to test/use the
lowlevel functions also for developers who don't have access neither to
Heiko's board nor to mine.
The patchset aims at implementing SPL support for the da850evm
configuration to allow booting this board from SPI flash without
using the UBL (see doc/README.davinci).
Major changes for v2:
- Added header files that contain the definition of the pinmux structs.
- Added code that actually loads u-boot from SPI flash and starts it.
This patchset is work in progress - I did for example not include
a feature requested by Heiko in [1]. Instead I just what to show
you the current state of my work and would like to ask you for comments.
The first patches move the pinmux functions from the board tree
to the arch tree and also use the in the lowlevel configuration
in arch/arm/cpu/arm926ejs/davinci/da850_lowlevel.c.
Patches #6 and #7 fix two problems I had during development.
The other patches add the SPL and fix mkimage for the building of AIS
images.
The patches apply on top of mainline u-boot and Heiko's patch
arm, arm926ejs: always do cpu critical inits
http://patchwork.ozlabs.org/patch/124787/
To build run
make da850evm_config
make u-boot.ais
Then program u-boot.ais to SPI flash on the da850evm.
Regards, Christian
