From 5075bf28d65c70cc777620ac7974adaac5d20095 Mon Sep 17 00:00:00 2001 From: Harald Seiler Date: Tue, 15 Dec 2020 16:47:49 +0100 Subject: [PATCH] nds32: Remove dead reset_cpu() implementation nds32 is one of the only architectures which still have a reset_cpu() implementation that makes use of the `addr` parameter. The rest of U-Boot now ignores it and passes 0 everywhere. It turns out that even here, reset_cpu() is no longer referenced anywhere; reset is either not implemented (e.g. ae3xx) or realized using a WDT (e.g. ag101). Remove this left-over implementation in preparation for the removal of the `addr` parameter in the entire tree.
