Hi all, Heiko Schocher added patches 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).
This patchset is not a complete implementation, it is missing the code that is actually used to load u-boot from SPI flash to the DDR memory. The code just hangs after the initialization is done. But I submit it nevertheless as RFC and I am looking forward to your comments.
The patches apply on top of git://git.denx.de/u-boot-ti.git and Heiko's patches
arm, arm926ejs: always do cpu critical inits http://patchwork.ozlabs.org/patch/124787/
arm, davinci: da850/dm365 lowlevel cleanup http://patchwork.ozlabs.org/patch/124788/
To build run
make da850evm_config make tools make u-boot.ais
Then program u-boot.ais to SPI flash. The board responds with an error message since we do hang() after the configuration.
Regards, Christian
