From 5a494607f07379cdb6ad5c1d03001b1eeda4b482 Mon Sep 17 00:00:00 2001 From: Andy Green Date: Wed, 13 Aug 2008 00:44:29 +0100 Subject: [PATCH] add-kernel-init.patch Huge patch boils down massive kernel image parsing and boot action to a modest sequence of code that actually boots the kernel.

This list is terminated by an "(uint32_t)0". + * Immediately after the terminating 0 follow the images, one by + * one, all aligned on "uint32_t" boundaries (size rounded up to + * a multiple of 4 bytes - except for the last file). + * + * "Firmware Images" are binary images containing firmware (like + * U-Boot or FPGA images) which usually will be programmed to + * flash memory. + * + * "Script files" are command sequences that will be executed by + * U-Boot's command interpreter;
