New Revision: 255939
URL: http://svnweb.freebsd.org/changeset/base/255939
Log:
Fix ixp425 boot2 with ARM EABI:
- libkern is missing __aeabi_llsl, implement this by calling __ashldi3.
- Because of how the asm entry macros are defined the boot2 code
requires the unwind symbols to exist, include them in boot2.
