You missed three that I sent you before. If you don't like my version of
CONFIG_MEMORY_SET I'm sure you can come up with a new one - but the other
two ought to be acceptable.
Physical memory size
CONFIG_MEMORY_SIZE
This sets the default memory size assumed by your SH kernel. It can
be overridden as normal by the 'mem=' argument on the kernel command
line. If unsure, consult your board specifications or just leave it
as 0x00400000 which was the default value before this became
configurable.
Darkness
CONFIG_MEMORY_SET
This is an option about which you will never be asked a question.
Therefore, I conclude that you do not exist - go away.
There is a grue here.
Cache and PCI noncoherent
CONFIG_SH_PCIDMA_NONCOHERENT
Enable this option if your platform does not have a CPU cache which
remains coherent with PCI DMA. It is safest to say 'Y', although you
will see better performance if you can say 'N', because the PCI DMA
code will not have to flush the CPU's caches. If you have a PCI host
bridge integrated with your SH CPU, refer carefully to the chip specs
to see if you can say 'N' here. Otherwise, leave it as 'Y'.
