I have some question about ioremap() function... In arch/ppc/mm/init.c file, there is ioremap() function.. What is the main functionality of ioremap()?
It takes two argument... I must use ioremap() for flash device.. I think first argument is physical address of memory mapped device, so I put that argument physical starting address of flash device. In my case, starting address of flash is 0XE4000000. and I use 4MB flash. Am I use virtual address for first argument? So I called ioremap() function with following line. ioremap(0xE4000000, 1024*1024*4); Am I correct? Please answer my question... ** Sent via the linuxppc-embedded mail list.
