[U-Boot] [PATCH 2/2] MPC8308RDB: minimal support for devboard from Freescale
Ilya Yanok
yanok at emcraft.com
Wed Jul 7 18:16:13 CEST 2010
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.
