Woo! Thanks Olaf. I was just about to sit down and write something like this myself. Looks good to me. I'll pick this up (but I'm going to move it to the fixup_device_tree_efika() function) Cheers, g. On 1/9/08, Olaf Hering [off-list ref] wrote:

The new network driver fec_mpc52xx will not work on efika because the firmware does not provide all required properties. http://www.powerdeveloper.org/asset/by-id/46 has a Forth script to create more properties. But only the phy stuff is required to get a working network. This should go into the kernel because its appearently impossible to boot the script via tftp and then load the real boot binary (yaboot or zimage). --- arch/powerpc/kernel/prom_init.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+)--- a/arch/powerpc/kernel/prom_init.c +++ b/arch/powerpc/kernel/prom_init.c@@ -1487,6 +1487,34 @@ static void __init prom_find_mmu(void) else if (strncmp(version, "FirmWorks,3.", 12) == 0) { of_workarounds = OF_WA_CLAIM | OF_WA_LONGTRAIL; call_prom("interpret", 1, 1, "dev /memory 0 to allow-reclaim"); +#ifdef CONFIG_PPC_MPC52xx + } else if (strcmp(version, "EFIKA5K2") == 0) { + call_prom("interpret", 1, 1, + " .\" Adding EFIKA5K2 Ethernet PHY\" cr" + " s\" /builtin\" find-device" + " new-device" + " 1 encode-int s\" #address-cells\" property" + " 0 encode-int s\" #size-cells\" property" + " s\" mdio\" 2dup device-name device-type" + " s\" mpc5200b-fec-phy\" encode-string s\" compatible\" property" + " 0xf0003000 0x400 reg" + " 0x2 encode-int" + " 0x5 encode-int encode+" + " 0x3 encode-int encode+" + " s\" interrupts\" property" + " new-device" + " s\" ethernet-phy\" 2dup device-name device-type" + " 0x10 encode-int s\" reg\" property" + " my-self" + " ihandle>phandle" + " finish-device" + " finish-device" + " s\" /builtin/ethernet\" find-device" + " encode-int" + " s\" phy-handle\" property" + " device-end" + ); +#endif } else return; _prom->memory = call_prom("open", 1, 1, ADDR("/memory"));_______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
