[U-Boot] [PATCH 2/2] mpc85xx: support for Freescale COM Express P2020
Ira W. Snyder
iws at ovro.caltech.edu
Tue Sep 27 23:30:46 CEST 2011
This adds support for the Freescale COM Express P2020 board. This board
is similar to the P1_P2_RDB, but has some extra (as well as missing)
peripherals.
Unlike all other mpc85xx boards, it uses a watchdog timeout to reset.
Using the HRESET_REQ register does not work.
