Patches Part 1 by Jon Loeliger, 11 May 2004:
Dynamically handle REV1 and REV2 MPC85xx parts. (Jon Loeliger, 10-May-2004). New consistent memory map and Local Access Window across MPC85xx line. New CCSRBAR at 0xE000_0000 now. Add RAPID I/O memory map. New memory map in README.MPC85xxads (Kumar Gala, 10-May-2004) Better board and CPU identification on MPC85xx boards at boot. (Jon Loeliger, 10-May-2004) SDRAM clock control fixes on MPC8540ADS & MPC8560 boards. Some configuration options for MPC8540ADS & MPC8560ADS cleaned up. (Jim Robertson, 10-May-2004) Rewrite of the MPC85xx Three Speed Ethernet Controller (TSEC) driver. Supports multiple PHYs. (Andy Fleming, 10-May-2004) Some README.MPC85xxads updates.
