This is roughly the sequence I followed.
1. Make the basic infrastructure.
2. Have a working skeleton of SPL(Just boots but doesn't do the loading
part yet)
3. Add mux support.
4. Add clock initialization
5. Add SDRAM initialization(clock patch is a pre-requisite for this)
6. Add support for MMC initialization and loading of U-Boot
7. Add FAT mode boot support.
8. Add support for Panda
I think this will change a bit when I do some squashing as you
suggested.
best regards,
Aneesh
