From 49655bb8a51565f0375a4f783334c9de78134be5 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 29 Sep 2012 20:29:49 +0200 Subject: bcma: just do the necessary things in early register on SoCs Some parts of the initialization for chip common and the pcie core are accessing the sprom struct, but it is not initialized at that stage. Just do the necessary thing in the early register on SoCs and not the complete initialization to read out the nvram from the flash chip. After it is possible to read out the nvram, the sprom should be parsed from it and the full initialization of the cores should be run. Signed-off-by: Hauke Mehrtens Signed-off-by: John W.
