This patch provides support for MPC8308RDB development board from Freescale with a minimal set of features: Dual UART is supported NOR flash is supported Both TSEC Ethernet controllers are supported PCI Express initialization is supported
The following features are enabled in configuration but not fully tested: I2C (used to get the board revision) I2C-connected RTC VSC7385 switch
There is one (hopefully) minor issue: on soft reset the board sometimes resets twice. I've not managed to find the fix for this problem yet. As a workaround instruction cache can be disabled.
