Add support for the MPC837xERDB
MPC837xERDB board support includes: * DDR2 330MHz hardcoded (soldered on the board) * Local Bus NOR Flash * I2C, UART and RTC * eTSEC RGMII (TSEC0 - RTL8211B with MII; * TSEC1 - VSC7385 local bus, hardcoded, requires seperate firmware * load) Signed-off-by: Kevin Lam <kevin.lam@freescale.com> Signed-off-by: Joe D'Abbraccio <joe.d'abbraccio@freescale.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
