In arch/ppc/boot, only r3 is used now, FWIW. > to > > * r3: ptr to bi_record Or so, yes. Look at the archives for discussions / flamewars about bi_records. > If the initrd is going to be passed with the bi_record, and the command line > already is there, then it's just the board info left. (for the 8xx anyhow) The initrd already is, right now. And yes, the bd_t would be passed, or phased out, see the above mentioned discussions / flamewars. > Or maybe there are zillions of applications booting the kernel directly > without the bootloader.. Something _always_ loads the kernel someplace. Call it what you will, but the thing moving the kernel to 0 and pressing go is the bootloader. Oh, and see the above mentioned discissions / flamewars :) -- Tom Rini (TR1265) http://gate.crashing.org/~trini/ ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
