Hi, these patches apply on top of Heiko Schocher's patches for the enbw_cmc board. They remove the duplicate functions for the power and sleep controller of the davinci devices.
The first patch renames the low level configuration functions since they can not only be used for the AM1808 but for the entire da850 family.
The second patch corrects the mask for the state bitfield of the MDSTAT registers. Similar patches have been already submitted for the Linux kernel and other parts of u-boot, see e.g. http://patchwork.ozlabs.org/patch/114942/
Patch number three adds a function to set an LPSC module to Sync Reset state as this is required for DDR memory controller initialization.
The forth patch finally replaces the PSC related functions in arch/arm/cpu/arm926ejs/davinci/da850_lowlevel.c by those of psc.c.
I tested the DDR initialization functions on my board and they worked fine, but of course I can only compile-test them for Heiko's board.
I am looking forward to your comments!
