From 648a1783fe2551f5a091c9a5f8f463cb2cbf8745 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 7 Apr 2023 14:09:09 +1000 Subject: powerpc/boot: Fix boot wrapper code generation with CONFIG_POWER10_CPU -mcpu=power10 will generate prefixed and pcrel code by default, which we do not support. The general kernel disables these with cflags, but those were missed for the boot wrapper.
