Hi Tadas,
I have most simple ppc405gp board and need to port bootloader, and linux to it. there is no aditional hardware just integrated 8mb ram cpu, ethernet, and one pci slot. so I should remove everything from any other board code to port it.
Yes!
Or more excactly, which board DO NOT have real time clock and preferably no fpga. and if the ram is integrated with no upgrade support it would be perfect.
I want to use its code as referense. if the board have something more then it is hard to remove.
Hmmm. I find it pretty easy to remove something from U-Boot. I would suggest to start with the CPCI4052 and remove all stuff you
don't need
(FPGA, RTC, etc.).
FPGA , RTC is easy to remove from u-boot, but I dont know how remove them from linux. and RTC seems to be vital part to run linux. (I found somewhere that it is nesecary to calculate bogomips) so probably some special driver is nesecary.
No, not needed at all! Just configure your kernel without RTC!
Best regards, Stefan
