* ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-0/+1
| | | | | | | | | | | | | | | | This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add support for ICON board (PPC440SPe)Stefan Roese2010-04-29-0/+88
This patch adds support for the Mosaix Technologies, Inc. ICON board, based on the AppliedMicro (AMCC) PPC440SPe. It's equipped with an SODIMM (512MB standard) and 64MByte of NOR FLASH. Support for the onboard SM502 will be added later. Signed-off-by: Stefan Roese <sr@denx.de>
