[PATCH] arm: mvebu: a38x: Remove dead code ARMADA_39X

5 Mar 2021

Config option ARMADA_39X is never set so remove all dead code hidden under
ifdef CONFIG_ARMADA_39X blocks.
Also remove useless checks for CONFIG_ARMADA_38X define as this macro is
always defined for a38x code path.
Signed-off-by: Pali Rohár pali@kernel.org
---
This patch depends on all previous a38x ddr patches.
