Hi: We use a mpc860t based board (2.4.20 kernel) and the addresses beyond 0xf0000000 are io-remapped. In driver space, to access memory mapped devices beyond this address i have some simple routines like in8/in16/in32 and out8/out16/out32 which basically use val = *addr or *addr = val kind of access.
I would like to use routines from asm-ppc/io.h file. But there are atleast two choices like insl/outsl or in_le32/out_le32. My problem is that I do not understand them well to use the correct one. I have searched for documents in the documentation directory and google search but could not find anything useful. It would be helpful if I can get some pointers on how to use functions in io.h file Thansk for your time, Nicholas. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
