Fixed rarp boot method for IA32 and other little-endian CPUs. * Patch by Marc Singer, 28 May 2003: Added port I/O commands. * Patch by Matthew McClintock, 28 May 2003 - cpu/mpc824x/start.S: fix relocation code when booting from RAM - minor patches for utx8245 * Patch by Daniel Engström, 28 May 2003: x86 update * Patch by Dave Ellis, 9 May 2003 + 27 May 2003: add nand flash support to SXNI855T configuration fix/extend nand flash support: - fix 'nand erase' command so does not erase bad blocks - fix 'nand write' command so does not write to bad blocks - fix nand_probe() so handles no flash detected properly - add doc/README.nand - add .jffs2 and .oob options to nand read/write - add 'nand bad' command to list bad blocks - add 'clean' option to 'nand erase' to write JFFS2 clean markers - make NAND read/write faster * Patch by Rune Torgersen, 23 May 2003: Update for MPC8266ADS board
