* Patch by Jon Loeliger, 02 Sep 2004:
Reset monitor size back to 256 so environment can be written to flash on MPC85xx ADS and CDS releases. * Patch by Paolo Broggini, 02 Sep 2004: Make BSS clearing on ARM systems more robust * Patch by Yue Hu and Joe, 01 Sep 2004: - add PCI support for ixp425; - add EEPRO100 suppor tfor ixdp425 board. * Fix problem with protected sector detection in driver/cfi_flash.c
