I have searched the Internet but I did not find any information to do that. FYI, this is the way it is done in ATAG: typedef struct { UINT32 start; UINT32 size; } LINUX_ATAG_INITRD2; The boot loader loads the initrd in system memory and passes the memory region information through ATAG. Sorry, if it is the wrong mailing-list. In this case, can someone point me on the right forum for any Linux FDT oriented questions. Thanks, Olivier
