Fixing the location of the ram oops buffer can lead to certain
kernel and boot loaders being confused when there is a ram
reservation low in the address space. Alternatively provide
a mechanism to allocate the ram oops buffer in cbmem. As cbmem
is usually high in the address space it avoids low reservation
confusion.
The patch uncondtionally provides a GOOG9999 ACPI device with
a single memory resource describing the memory region used for
the ramoops region.
BUG=None
BRANCH=baytrail,haswell
TEST=Built and booted with and w/o dynamic ram oops. With
the corresponding kernel change things behave correctly.

In order for userland to create rmodules the common code should be
shareable. Therefore, convert the short u<width> name types to the
posix uint<width>_t types. Additionally, move the definition of the
header structure to a new rmodule-defs.h header file so that userland
can include that without pulling in the coreboot state.

Boot speeds can be sped up by mirroring the payload into
main memory before doing the actual loading. Systems that
would benefit from this are typically Intel ones whose SPI
are memory mapped. Without the SPI being cached all accesses
to the payload in SPI while being loaded result in uncacheable
accesses. Instead take advantage of the on-board SPI controller
which has an internal cache and prefetcher by copying 64-byte
cachelines using 32-bit word copies.

This is based on the RCBA configuration setup from haswell.
It handles PCI, BARs, IO, MMIO, and baytrail-specific IOSF.
I did not extend it to handle MSR yet but that would be another
potential register type.
There are a number of approaches to this kind of thing, but in the
end they have a lot of switch statements and a mass of #defines.
I'm not particularly set on any of the details so comments welcome.

Divisor is a function of requested baudrate, platform-specific
reference clock and amount of oversampling done on the UART reference.
Calculate this parameter with divisor rounded to nearest integer.
When building without option_table or when there is no entry for
baud_rate, CONFIG_TTYS0_BAUD is used for default baudrate.
For OxPCIe use of 4 MHz for reference was arbitrary giving correct
divisor for 115200 but somewhat inaccurate for lower baudrates.
Actual hardware is 62500000 with 16 times oversampling.
FIXME: Field for baudrate in lb_tables is still incorrect.

With the recent improvement 3d6ffe76f8a505c2dff5d5c6146da3d63dad6e82,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.
CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency
Remove this as a buggy feature until we figure out how to do it properly
if necessary.

Certain CPUs require the default SMM region to be backed up
on resume after a suspend. The reason is that in order to
relocate the SMM region the default SMM region has to be used.
As coreboot is unaware of how that memory is used it needs to
be backed up. Therefore provide a common method for doing this.

There are 2 methods currently available in coreboot to load
ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.
To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.

On x86, log2() is defined as an inline function in arch/io.h. This is
a remnant of ROMCC, and forced us to not include clog2.c in romstage.
As a result, romstage on ARM has no log2().
Use the inline log2 only with ROMCC, but otherwise, use the one in
clog2.c.

CBMEM console buffer size is adjustable in menuconfig, but this would
not correctly adjust the overall allocation made for CBMEM.
HIGH_MEMORY_SIZE is aligned to 64kB and definitions are moved down in
the header file as HIGH_MEMORY_SIZE is not used with DYNAMIC_CBMEM.
Try to continue boot even if CBMEM cannot be created. This error would
only occur during development of new ports anyways and more log output

This includes the new dp code, which is better, and the fimd code,
which is changed and improved. We took the chance to remove un-needed
files, and also to remove some foolish u-boot habits, but not all of
them. That will take time.
With these changes we get graphics.
Since the only mainboards we have with 16 bit graphics are 5:6:5,
adjust edid.c to just use that format. If at some future time we need
4:4:4, which seems unlikely, we'll need to add a function to adjust
the lb_framebuffer. Note that you can't just divine this from the EDID,
as the graphics pipe format need not match the actual final format used.
The EDID reading works. We've been requested to support hard-coded
EDIDs and that will come in the next revision. Currently the hard-coded
EDID is ignored for testing.

Now that there is a clearly defined boot state machine
we can add some useful post codes to indicate the current
point in the state machine by having it log a post code
before the execution of each state.
This removes the currently defined POST codes that were
used by hardwaremain in favor of a new contiguous range
that are defined for each boot state.
The reason for this is that the existing codes are mostly
used to indicate when something is done, which is confusing
for actual debug because POST code debugging relies on knowing
what is about to happen (to know what may be at fault) rather
than what has just finished.
One additonal change is added during device init step as this
step often does the bulk of the work, and frequently logs POST
codes itself. Therefore in order to keep better track of what
device is being initialized POST_BS_DEV_INIT is logged before
each device is initialized.
interrupted boot with reset button and
gathered the eventlog. Mosys has been extended to
decode the well-known POST codes:

Many chipset devices require additional configuration after
device init. It is not uncommmon for a device early in the devicetree
list to need to change a setting after a device later in the tree does
PCI init. A final function call has been added to device ops to handle
this case. It is called prior to coreboot table setup.
Another problem that is often seen is that the chipset or mainboard
need to do some final cleanup just before loading the OS. The chip
finalize has been added for this case. It is call after all coreboot
tables are setup and the payload is ready to be called.
Similar functionality could be implemented with the hardwaremain
states, but those don't fit well in the device tree function pointer
structure and should be used sparingly.

Some development kits with USB 2.0 HS OTG have an USB hub instead
of being directly connected to the USB host/device controller.
Send the necessary initialisation sequence, using HUB CLASS requests
of PORT_POWER and PORT_RESET to enable a pre-selected port number
where a device supporting debug descriptor is located.
This also adds the Kconfig option for BeagleBone.

For both romstage and ramstage, this calls an arch-specific function
get_cbmem_table() to resolve the base and size of CBMEM region. In ramstage,
the result is cached as the query may be relatively slow involving multiple PCI
configuration reads.
For x86 CBMEM tables are located right below top of low ram and
have fixed size of HIGH_MEMORY_SIZE in EARLY_CBMEM_INIT implementation.

Transaction consistently completes with 80 to 150 status reads on my
setups. Hardware should always be able to complete this within 125us
as the debug port is serviced at the beginning of each microframe.
Timeout is set to DBGP_MICROFRAME_TIMEOUT_LOOPS=1000 status reads. Do not
retry transactions if this timeout is reached as the host controller
probably needs full re-initialisation to recover.
If this timeout is not reached, but a transaction is corrupted
on the wire, or it is otherwise not properly delivered to the USB device,
transaction is retried upto DBGP_MICROFRAME_RETRIES=10 times.
