Hi,
I would like to get some help to port u-boot on a new hardware (the hardware is still under heavy development).
I have listed the following issues which I've encountered while reading the README and browsing the source tree.
1. My board has an ARM920T core. Instinctively, I would choose a "template" board support subdirectory that has the same core. If my platform is very different from the template, can I just choose the board that fits my needs (e.g. UART, FLASH, MEMORY MAP, etc.) and just re-configure the core? If this is possible, how do I do this?
2. My UART port is 16550 compliant. The ARM920T core (cpu/arm920T/) is using a serial.c that is compliant to S3C24XX. Can I just simply overwrite cpu/arm920t/serial.c with 16550 compliant serial.c?
3. Can somebody please tell me the files that are most-likely to change when porting u-boot to a new platform? Currently I am modifying the following:
board/myboard /* copied from board smdk2410 */ - What should be placed here? Initialization routines? What is the "minimal" requirement for this subdirectory?
Makefile - to make our board noticable to the main kernel tree
include/configs/myboard.h
4. Are there other important files to modify in order to build the proper u-boot image?
Please advise on the stated issues. Thank you very much.
Regards, Rodel Miguel
