[U-Boot] [PATCH 0/4] Support nds32 pre-build toolchain
From: Rick Chen rick@andestech.com
1. Support nds32 pre-build toolcahin for buildman. 2. Fix some bugs about fpu and toolchain issues.
Rick Chen (4): .travis.yml: Support nds32 prebuilt toolchain nds32: Remove gcc unused option nds32: Generate SW fpu instruction. nds32: Fix boot fail issue when build with elf-mculib.

-G0 is an old option, not support now, So remove it. It can help to fix compile error when build with nds32 pre-build toolchain.

Force it to generate SW fup instruction. It help to avoid bugs when running on no-HW-fpu board, but compile with v3f which support HW fpu instruction.

Add -mcmodel=large can let elf-mculib have the same default behavior just like linux-glibc. And it help to pass U-Boot booting sequence.
