* davinci: split out some dm644x-specific bits from pscDavid Brownell2009-06-12-75/+28
| | | | | | | | | | | | | | Split out DaVinci DM6446-specific bits from more generic bits: - Add a CONFIG_SOC_DM644X. All current boards use DM6446 chips; DM6443 and DM6441 chips differ in available peripherals. - Move most DM644X-specific bits from psc.c to a new dm644x.c file, which is conditionally built. It provides device-specific setup. Plus minor coding style and comment updates with respect to the PSC. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* davinci: move psc support board-->cpuDavid Brownell2009-06-12-0/+182
Move DaVinci PSC support from board/* to cpu/* where it belongs. The PSC module manages clocks and resets for all DaVinci-family SoCs, and isn't at all board-specific. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
