Perhaps lib_mips/mips_linux.c in the U-Boot tree is what you are looking for.
That code sets up environment parameters that are parsed by the Linux kernel
later on (see rd_start_early() and friends in arch/mips/kernel/setup.c in the
Linux tree).
Thanks! That is exactly what I was looking for. However, I noticed
that U-BOOT passes these parameters in environment variables, where as
Linux kernel expects them as command l ine arguments. It wasn't
working for me untill I made changes in U-BOOT to pass them in command
line arguments.
Why is this discrepancy in U-BOOT and the kernel? Are other people
working on the (linux+U-BOOT) combo making the changes that I did?
Thanks,,
