33e5df3f25 Set PCI bus operations at buildtime for ramstage
PCI bus operations are static through the ramstage, and should be
initialized from the very beginning. For all the replaced instances,
there is no MMCONF_SUPPORT nor MMCONF_SUPPORT_DEFAULT selected for
the northbridge, so these continue to use PCI IO config access.

0aa37c488b sconfig: rename lapic_cluster -> cpu_cluster
The name lapic_cluster is a bit misleading, since the construct is not local
APIC specific by concept. As implementations and hardware change, be more
generic about our naming. This will allow us to support non-x86 systems without
adding new keywords.

4aff4458f5 sconfig: rename pci_domain -> domain
The name pci_domain was a bit misleading, since the construct is only
PCI specific in a particular (northbridge/cpu) implementation, but not
by concept. As implementations and hardware change, be more generic
about our naming. This will allow us to support non-PCI systems without
adding new keywords.

5079a0d32f Remove assembly coded log2 function
As we move to supporting other systems we need to get rid of assembly
where we can. The log2 function in src/lib is identical to the assembly
one (tested for all 32-bit signed integers :-) and takes about 10 ns
to run as opposed to 5ns for the non-portable assembly version. While speed
is good, I think we can spare the 15 ns or so we add to boot time
by using the C version only.

4b42a62966 Factor out a few commonly duplicated functions from northbridge.c.
The following functions are moved to devices/device_util.c:

 - ram_resource()

 - tolm_test()

 - find_pci_tolm()

There are only two tolm_test() / find_pci_tolm() which differ from the
defaults, one of them can easily be eliminated in a follow-up patch,
maybe even both, but for now keep it simple and only eliminate the majority.

8463dd9db0 Rename build system variables to be more intuitive, and
at the same time let the user specify sources instead
of object files:
- objs becomes ramstage-srcs
- initobjs becomes romstage-srcs
- driver becomes driver-srcs
- smmobj becomes smm-srcs

The user servicable parts are named accordingly:
ramstage-y, romstage-y, driver-y, smm-y

Also, the object file names are properly renamed now, using
.ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently.

Remove stubbed out via/epia-m700 dsdt/ssdt files - they didn't
easily fit in the build system and aren't useful anyway.

753169dc25 Kconfig builds all boards now.
This patch also aligns the configuration of a couple of
boards more closely to what newconfig does.

Also, the romstrap inc/lds files are declared in the
Makefiles of the southbridges they belong to, instead of
some global file.

AMD CPUs have their own timer functions, so disable UDELAY_IO
for them and set HAVE_INIT_TIMER as appropriate, same for
emulation/qemu-x86.

29cc9eda20 Move the v3 resource allocator to v2.
Major changes:
1. Separate resource allocation into:
	A. Read Resources
	B. Avoid fixed resources (constrain limits)
	C. Allocate resources
	D. Set resources

Usage notes:
Resources which have IORESOURCE_FIXED set in the flags constrain the placement
of other resources.  All fixed resources will end up outside (above or below) 
the allocated resources.

Domains usually start with base = 0 and limit = 2^address_bits - 1.

I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is
still there for resources.  Some platforms may want to change that, but I didn't
want to break anyone's board.

Resources are allocated in a single block for memory and another for I/O.
Currently the resource allocator doesn't support holes.
