It makes the porting lots easier. Sure. But where can I find the standard rules ? Are the rules dependent on each demo board like 8560_ads ? Do the custom boots respect some rules ? > I open 2 TLBs on memory and a big TLB for all IOs included CSSRBAR. > How do you to this?  The linux ppc kernel already manages all > of this mapping for you. Right. I let the kernel configure the memory TLBs but I use a call to io_block_mapping to open the IO space io_block_mapping(0xf0000000, 0xf0000000, 0x10000000, _PAGE_IO); Thanks again Bye Laurent
