[coreboot] [commit] r6213 - in trunk/src: drivers/dec/21143 mainboard/nokia/ip530

[repository service]

Author: stepan
Date: Sun Dec 26 17:49:57 2010
New Revision: 6213
URL: https://tracker.coreboot.org/trac/coreboot/changeset/6213

Log:
All the values should stay untouched or be set automatically by the resource
allocator. If that does not work out, they should be set in the code. Setting
them in Kconfig is the worst possible thing to do.
