Hi

I have a general question about the startup of a 8260 based system.


Are the following assumptions right and in the correct order:

1. The bootloader sets all chipselects (Buswidth, startaddress, size).

2. The kernel relies on these values and doesn't change them. It doesn't
enable any additional chipselects.

3. The kernel sets up the MMU.

4. The kernel enables the the data and instruction cache.
