From b81655333f0a7378eec66cfef668a7282d7a4b17 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Tue, 15 Nov 2011 08:39:01 -0500 Subject: Remove "CS3" prefix from libmaple symbol names. We're no longer even marginally compatible with CS3, so it's inappropriate to use that prefix in our names. Rename: __cs3_stm32_vector_table -> __stm32_vector_table. __cs3_stack -> __msp_init __cs3_reset -> __exc_reset __cs3_start_c -> start_c Also add an MIT license header and assert LeafLabs copyright over wirish/start.S and wirish/start_c.c. These files are modified from the original CodeSourcery versions, which were distributed under a license that permits modifications to be distributed under a different copyright and licensing terms than the originals.
