From: Daniel Schwierzeck Date: Sun, 23 Sep 2018 17:15:17 +0000 (+0200) Subject: MIPS: fix linking of standalone programs X-Git-Tag: v2019.01-rc1~31^2 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1bef0c530beaaba08b8ca7a9ec6ce6dc25f62dfb;p=oweals%2Fu-boot.git MIPS: fix linking of standalone programs Use the global MIPS specific u-boot.lds for linking standalone programs instead of the outdated ones in examples/standalone/. Also pass --gc-sections in LDFLAGS_STANDALONE to optimize the size of standalone programs. Finally remove the deprecated config.mk files in arch/mips/cpu/mips[32,64]/.
