Subject: MIPS: ath79: Fix the DDR control initialization on ar71xx and ar934x
From: Alban Bedel <[email protected]>
commit 5011a7e808c9fec643d752c5a495a48f27268a48 upstream.
The DDR control initialization needs to know the SoC type, however
ath79_detect_sys_type() was called after ath79_ddr_ctrl_init().
Reverse the order to fix the DDR control initialization on ar71xx and
ar934x.
