Small 4xx fixes for 2.6.24
Subsystems (3)
cover Small 4xx fixes for 2.6.24
This series of patches enables the EMAC driver for the Ebony, Walnut, and Bamboo boards. There's also a timebase fix for Walnut.
I'll put these and a few other patches that have been sent to me into my git tree later today and ask Paul to pull.

PATCH 2/4 4xx: Fix timebase clock selection on Walnut
In reply to Josh BoyerThe current bootwrapper fails to set the timebase clock to the CPU clock which causes the time to increment incorrectly. This fixes it by using the correct #define for the CPC0_CR1 register.

PATCH 3/4 4xx: Enable EMAC for PPC405 Walnut board
In reply to Josh BoyerThis patch enables the ibm_newemac driver for the Walnut board. It fixes the device tree for the walnut board to order the MAL interrupts correctly and adds the local-mac-address property to the EMAC node. The bootwrapper is also updated to extract the MAC address from the OpenBIOS offset where it is stored.
