From ef11df6b66ecf5797e94ba322254b8fb7a4e2e12 Mon Sep 17 00:00:00 2001 From: John Rigby Date: Tue, 5 Aug 2008 17:38:57 -0600 Subject: mpc5121: squash some fdt fixup errors On ADS5121 when booting linux the following errors are seen: Unable to update property /soc5121@80000000:bus-frequency, err=FDT_ERR_NOTFOUND Unable to update property /soc5121@80000000/ethernet@2800:local-mac-address, err=FDT_ERR_NOTFOUND Unable to update property /soc5121@80000000/ethernet@2800:address, err=FDT_ERR_NOTFOUND This is caused by ft_cpu_setup trying to deal with both old and new soc node naming. This patch fixes this by being smarter about what to fixup. Also do soc node fixups by compatible instead of by path. A new board config called OF_SOC_COMPAT defined to be "fsl,mpc5121-immr" replaces the old OF_SOC node path that was defined to be "soc@80000000". Old device trees still work, but the compatiblity is conditional on CONFIG_OF_SUPPORT_OLD_DEVICE_TREES which is on by default in include/configs/ads5121.h.
