Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ Information about the Linux/PPC kernel images
+Please mail me (Cort Dougan, email@example.com) if you have questions,
+comments or corrections.
+This document is meant to answer several questions I've had about how
+the PReP system boots and how Linux/PPC interacts with that mechanism.
+It would be nice if we could have information on how other architectures
+boot here as well. If you have anything to contribute, please
+let me know.
+1. PReP boot file
+ This is the file necessary to boot PReP systems from floppy or
+ hard drive. The firmware reads the PReP partition table entry
+ and will load the image accordingly.
+ To boot the zImage, copy it onto a floppy with dd if=zImage of=/dev/fd0h1440
+ or onto a PReP hard drive partition with dd if=zImage of=/dev/sda4
+ assuming you've created a PReP partition (type 0x41) with fdisk on
+ The layout of the image format is:
+ 0x0 +------------+
+ | | PReP partition table entry
+ | |
+ 0x400 +------------+
+ | | Bootstrap program code + data
+ | |
+ | |
+ | | compressed kernel, elf header removed
+ | | initrd (if loaded)
+ | | Elf section table for bootstrap program
+2. MBX boot file
+ The MBX boards can load an elf image, and relocate it to the
+ proper location in memory - it copies the image to the location it was
+ linked at.
