Tue Sep 19 18:31:58 CEST 2006
From: Timur Tabi <timur at freescale.com>
PREREQUISITE PATCHES:
* This patch can only be applied after the following patches have been applied:
1) DNX#2006090742000024 "Add support for multiple I2C buses"
2) DNX#2006090742000033 "Multi-bus I2C implementation of MPC834x"
3) DNX#2006091242000041 "Additional MPC8349 support for multibus i2c"
4) DNX#2006091242000078 "Add support for variable flash memory sizes on 83xx systems"
5) DNX#2006091242000069 "Add support for Errata DDR6 on MPC 834x systems"
CHANGELOG:
* Add support for the Freescale MPC8349E-mITX reference design platform.
The second TSEC (Vitesse 7385 switch) is not supported at this time.
