Subject: [U-Boot] [PATCH 3/3] MIPS: fix linking of standalone programs
Date: Sun, 23 Sep 2018 19:15:17 +0200 [thread overview]
Message-ID: <20180923171517.21363-4-daniel.schwierzeck@gmail.com> (raw)
In-Reply-To: <20180923171517.21363-1-daniel.schwierzeck@gmail.com>
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instead of the outdated ones in examples/standalone/.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]/.
