[ARM] TI DaVinci support, hopefully final
Add support for the following DaVinci boards: - DV_EVM - SCHMOOGIE - SONATA Changes: - Split into separate board directories - Removed changes to MTD_DEBUG (or whatever it's called) - New CONFIG_CMD party line followed - Some cosmetic fixes, cleanup etc. - Patches against the latest U-Boot tree as of now. - Fixed CONFIG_CMD_NET in net files. - Fixed CONFIG_CMD_EEPROM for schmoogie. - Made sure it compiles and works (forceenv() link problem) on SCHMOOGIE and DV_EVM. Can't check if it works on SONATA, don't have a board any more, but it at least compiles. Here is an excerpt from session log on SCHMOOGIE...
