Note that the 8xx rom boot loader occupies around 500k. Yes, I can say it will not work. The code in the arch/ppc/mbxboot directory, which is used for all 8xx and 8260 processors, assumes there is memory above 4 MB it can use for buffer space while decompressing the kernel. You can play around with adjusting these addresses and sizes, and get a kernel to boot. You will get a shell prompt, and that is about all. You won't be able to use a ramdisk, you probably won't be able to execute any useful programs. -- Dan -- I like MMUs because I don't have a real life. ** Sent via the linuxppc-embedded mail list.
