rename milkymist-ng to MiSoC
2013-11-09 09:27:32 -05:00
MSCDIR=../..
include $(MSCDIR)/software/common.mak
Copy some software code from the original Milkymist SoC. Libbase should keep its RAM usage to a minimum as it is meant to be executed before the SDRAM is up and running. (Having lots of code is OK though as we XIP from the flash)
2012-02-03 06:08:17 -05:00
Add a stub getenv() implementation. This is not strictly necessary to build libunwind (it can be built with -DNDEBUG), but it will be handy while it is debugged. It can be removed afterwards.

libbase.a: $(OBJECTS) vsnprintf.o
common.mak: remove RANLIB. `ranlib` is not necessary on any system we can possibly build for, as it is superseded by `ar s` for the last ten years or so (at least). Thus, change ar invocations to `ar crs`, also removing a `l` flag that is ignored by binutils.
