S/F core

Dear everyone, My nos2 is 50Mhz, S -core, has been tested, all is ok! when I change to 50M/F-core, select the instruction cache and data cache, the "netflash" command is not ok...

I think it is a bug of Nios2 kernel. (Scott noted it in 2004.)

Please update,

__ioremap() in file arch/nios2nommu/mm/ioremap.c

/*

* Map some physical address range into the kernel address space.

*/

void *__ioremap(unsigned long physaddr, unsigned long size, int cacheflag)

{

return (void *)(physaddr | 0x80000000); // uncached

}
