899d13d0df cbfs: new API and better program loading
A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.

All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.

The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

e1133b7d7d kbuild: automatically include northbridges
This change switches all northbridge vendors and southbridges
to be autoincluded by Makefile.inc, rather than having to be
mentioned explicitly in northbridge/Makefile.inc or in
northbridge/<vendor>/Makefile.inc.

This means, vendor and northbridge directories are now "drop
in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.

The long term plan is to enable out of tree components to be
built with a given coreboot version (given that the API did not
change).

a173a6255b Remove guarding #includes by CONFIG_FOO combinations
First of many to remove guarding the inclusion of headers based on
CONFIG_ options. This *potentially* could hide issues such as functions
being swapped from under our feet, since different runtime behaviour
could be declared with the function same name and type-signature. Hence,
depending on the header we happen to get may change runtime behaviour.

24d1d4b472 x86: Unify arch/io.h and arch/romcc_io.h
Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

6fe0cab205 Extend CBFS to support arbitrary ROM source media.
Summary:
	Isolate CBFS underlying I/O to board/arch-specific implementations as
	"media stream", to allow loading and booting romstage on non-x86.

	CBFS functions now all take a new "media source" parameter; use
	CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
	API Changes:
		cbfs_find => cbfs_get_file.
		cbfs_find_file => cbfs_get_file_content.
		cbfs_get_file => cbfs_get_file_content with correct type.

CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.

To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media".  To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.

Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media).  Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
	struct cbfs_file *entry = cbfs_get_file(media, name);
	void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);

Test results:
 - Verified to work on x86/qemu.
 - Compiles on ARM, and follow up commit will provide working SPI driver.

5e29f00c55 Intel and GFXUMA: drop redundant use of lb_add_memory_range()
Use of uma_resource() in northbridge code created a memory
resource marked as reserved. Such resources are removed
from system memory in write_coreboot_table().

6ff1d36a47 Intel and GFXUMA: fix MTRR and use uma_resource()
Commit 2d42b34003 changed the
variable MTRR setup and removed compensation of uma_memory_size in
the cacheable memory resources.

Since the cacheable region size was no longer divisible by a large
power of 2, like 256 MB, this caused excessive use of MTRRs.
As first symptoms, slow boot with grub and poor user response.

As a solution, register the actual top of low ram with ram_resource(),
and do not subtract the UMA/TSEG regions from it.

TSEG may require further work as the original did not appear exactly
right to begin with. To have UMA as un-cacheable, use uma_resource().

No need for the test, tomk is at most 1GB on these chipsets.
Even if there was no room, adjusting the memory resource would not
not divert accesses in the hardware from DRAM to PCI.

cc55b9b919 Define global uma_memory variables
Use of the uma_memory_base and _size variables is very scattered.
Implementation of setup_uma_memory() will appear in each northbridge.

It should be possible to do this setup entirely in northbridge
code and get rid of the globals in a follow-up.

8301d8348a second round name simplification. drop the <component>_ prefix.
the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.

Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)

- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong

d773fd370a Some more DIMM0 related cleanups and deduplication.
- VIA VT8235: Do the shift in smbus_read_byte() as all other chipsets do.

 - spd.h: Move RC00-RC63 #defines here, they were duplicated in lots of
   romstage.c files and lots of spd_addr.h files. Don't even bother for
   those spd_addr.h which aren't even actually used, drop them right away.

 - Replace various 0x50 hardcoded numbers with DIMM0, 0x51 with DIMM1,
   and 0xa0 with (DIMM0 << 1) where appropriate.

 - Various debug.c files: Replace SMBUS_MEM_DEVICE_START with DIMM0,
   SMBUS_MEM_DEVICE_END with DIMM7, and drop useless SMBUS_MEM_DEVICE_INC.

 - VIA VX800: Drop unused SMBUS_ADDR_CH* #defines.

 - VIA VT8623: Do the shift in smbus_read_byte() as all other chipsets do.
   Then, replace 0xa0 (which now becomes 0x50) with DIMM0.

 - alix1c/romstage.c, alix2d/romstage.c: Adapt to recent bit shift changes.

 - Various files: Drop DIMM_SPD_BASE and/or replace it with DIMM0.

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.
