From 6433fa202a91a6594dd48f06807ac38ba27fa0bb Mon Sep 17 00:00:00 2001 From: Larry Johnson Date: Mon, 17 Mar 2008 11:10:35 -0500 Subject: ppc4xx: Updates to Korat-specific code This patch contains updates for changes for the Korat PPC440EPx board. These changes include: (1) Support for "permanent" and "upgradable" copies of U-Boot, as described in the new "doc/README.korat" file; (2) a new memory map for the registers in the board's CPLD; (3) a revised format for manufacturer's data in serial EEPROM; and (4) changes to track updates to U-Boot for the Sequoia board.
