You can download the kernel, but it will not run ;-) The Linux kernel relies on a lot of initialization to be done by the firmware - things like initializing and sizing the memory, passing boot arguments etc.
This is perfect timing on my part, I have a project to port PPC Linux to a custom board that is based on an 8245. I've been searching on and off for the last few days to try and get a handle on the low level files, i.e. platform/* or ppc/kernel/* and how they are interrelated. I've also tried to understand what files I will need to create, i.e. newBoardFoo_setup.c or newBoardBar() in head.S. My upfront question(s) to this group, and those who frequent the PPCBoot list is: Can you give me pointers of Doc's, white papers or even a Doctoral Thesis to read up on to understand what I will need to do for a New Board LSP effort. Along with this, what documents might describe the interface/interactions needed for the PPCLinux kernel and the PPCBoot support. I'm not looking to be spoon fed this stuff (honest), even an RTFM will be fine if you can tell me where the FM's are.
I suggest you start porting PPCBoot.
Well I planned on it, but after the Kernel work. Perhaps it is time to readdress the schedule :-) Thanks a lot! -------------------------------------------- John A.
