[coreboot] [v2] r4254 - trunk/coreboot-v2/src/arch/i386/lib

Author: oxygene

New Revision: 4254

Modified:
   trunk/coreboot-v2/src/arch/i386/lib/copy_and_run.c
Log:
Fix a bug introduced in the copy_and_run refactoring.
The new code always decompressed to dst (as it should)
and then jumped to _iseg, when it should jump to dst.

With dst != _iseg this breaks (coreboot_apc)
