Jordan Crouse 2c7bb9e84f libpayload: Add -Os to the CFLAGS Adding -Os to the CFLAGS gains us about 25% smaller code (give or take). Unfortunately, it exposes a strange issue where strcpy() suddenly goes missing - we think that strcpy() is being provided by libgcc, and that for some reason, -Os changes the beahavior. Oh, well - add a quick strcpy() function and we're good.

README

This is libpayload, a minimal library to support standalone payloads
that can be booted with firmware like coreboot.  It handles the setup
code, and provides common C library symbols such as malloc() and
printf().

Please see the sample/ directory for an example of the payload in
action.
