updates for the siemens am335x based boards: - draco: add delay for DDR3 configuration - change MTD partition layout and add a possibility to redefine MTD layout in board header. - move ubi support to common header file - draco: improve dtb naming - draco: set CONFIG_SYS_CBSIZE to 1024 - add generic env based led Leds can now be defined in Environment - add generic env based dfu button Which gpio is used for the dfu button can be defined through the Environment - set MACH_TYPE only if defined - draco: increase CPU freq to 300MHz - Add time command to siemens am33xx boards - DDR3: increase default tRFC - draco: enable pullup for DFU and ERST pin - change print format DDR3 Signed-off-by: Samuel Egli <samuel.egli@siemens.com> Acked-by: Heiko Schocher <hs@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Heiko Schocher <hs@denx.de>
