From 8db0c9d416f26018cb7cabfb0b144f5108e29735 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 10 Jul 2018 00:24:25 +1000 Subject: [PATCH] powerpc: Add ppc32_allmodconfig defconfig target Because the allmodconfig logic just sets every symbol to M or Y, it has the effect of always generating a 64-bit config, because CONFIG_PPC64 becomes Y. So to make it easier for folks to test 32-bit code, provide a phony defconfig target that generates a 32-bit allmodconfig. The 32-bit port has several mutually exclusive CPU types, we choose the Book3S variants as that's what the help text in Kconfig says is most common.
