[okl4-developer] About the cache support of arm926ej-s

[kashin Lin]

Hi,

when using cache on arm926ej-s, it should configure the memory region you
want to cache as cacheable in page table first and
set eanble cache bit in coprocessor's register. i wonder does OKL4 using
cache mechanism on arm926ej-s?

if it does, what memory regions are set as cacheable? can the cacheable
memory region be configured by user? how?

in an iguana application, are there any cache operations api can be called?
especially invalid or write back specific cache line.


thanks in advance.

best,
kashin lin
