The config file which cbootimage processes to create a BCT could come from
multiple different files, individually selected based on config options,
and/or split up into different files for organizational purposes. This change
adds a special-class which collects those files and concatenates them all
together in a bct.cfg which can be processed more easily by other parts of the
build.
While the BCT files themselves are potentially very board specific, for
instance ones that hold memory timing information, this bit of code which
collects them is not. It has to be in each board file instead of alongside the
CPU, however, to ensure that the special class is set up before another
Makefile tries to use it. If we end up with lots of Tegra based boards which
duplicate this code over and over, we might want to revisit how this works.

This commit always selects COLLECT_TIMESTAMPS and starts
tracking TSC values from the early stages of bootblock.
The initial timestamp value is saved in mm0 and mm1 while
in bootlbock. This approach works because romcc is not configured
to use mmx registers for its compilation.
Additionally, the romstage api with the mainboard was changed to
always pass around a pointer to a romstage_params structure as the
timestamps are saved in there until ram is up.

Peppy had some issues with FUI. We decided it was time to create
peppy-specific gma.c and i915io.c files. Using yabel and the i915tool,
we generated a replay attack, then interpolated against the slippy
i915io.c to get something working.
Also, in preparation for moving code out of the mainboard gma.c to
generic driver code, we got rid of some hardcodes in the mainboard
gma.c that have no business being there. The worst were the
computation of gmch_[m,n] and it turns out that we had some
long-standing bugs related to confusion about 'bpp'. I've killed the
word bpp everywhere I could because there are at least 3 things that
correspond to bpp. We now have framebuffer, pipe, and panel bpp. The
names are long because I want to avoid all the mistakes we've all been
making in the last year :-) Sadly, that means a lot of changes not just
peppy-related, but they are simple and in a good cause.
The test pattern generation is driven by a global variable in
mainboard/peppy/gma.c. I've found in the past that it's very useful
to have a function like this available, as one can activate it while
using a jtag debugger: halt at the right place in ramstage, set the
variable to 1, continue. It's not enough code to worry about always
including.
The last hard-codes for M and N registers are gone, and the function
to set from generic intel_dp.c code works. To avoid screen trash on a
dev mode boot, which we liked but nobody else did :-), we now take the
time to put a pleasing background color that sort of doubles as a
power LED.
Rough timing is ramstage start is at 2.2, and dev setup is done at
3.3. These new platforms are depressingly slow to boot. Rom init alone
is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash
prompt. These CPUs are at least 10x faster and take much longer to get going.
Future work, once we get this through, is to move more functions to the
intel driver, and combine the mainboard i915io.c into the mainboard gma.c.
That separation only existed because i915io.c was generated by a tool, and it
had lots of ugliness. Most ugliness is gone.
BUG=None
TEST=build and boot on peppy and get a screen, in both dev and normal modes.

While the 8250 compatible serial port driver is primarily useful on x86
systems because it works with the legacy x86 com ports, some devices which
aren't x86 based have 8250 compatible UARTs as well. This change renames the
CONFIG_X86_SERIAL_CONSOLE option to the more general and direct
CONFIG_8250_SERIAL_CONSOLE and fixes up the dependencies so that non-x86
systems can enable the driver, although it will default to on on x86 and off
otherwise.
Also, the default IO port address that's added to the sysinfo structure on x86
and which is intended to be overwritten by a value in the coreboot tables is
not used on ARM. That variable is adjusted so that it's more clear it's a
default value, and made dependent on x86 since that's the only place its value
is actually used.

The USB MSC device structure contains a "ready" state that can be either
"ready", "not ready" or "detached". The last one can only be assigned
when the device is completely unresponsive and gets forcefully logically
detached via usb_detach_device(). This call (at least in the current
version) also calls all destructors and frees the complete usbdev_t
structure (including the MSC specific part), which unfortunately makes
storing the "detached" state in that very structure a little pointless.
This patch reduces the "ready" value to a simple boolean and makes sure
that all detachment cases immediately return from the MSC driver,
carefully avoiding any use-after-free opportunities.

When USB3 devices are attached while in suspend, or two USB3 devices
that are both plugged in are switched to the other port while in
suspend the kernel does not seem to notice this -- despite the cold
attach status bit. This results in the devices showing up in the USB
list at the old enumerated device numbers and higher layers continuing
to think they are present but not reseponding.
With the kernel workaround to deal with devices that are logically
disconnected it is possible for firmware to send a warm port reset to
devices that are in this state and then the kernel will see them disappear
and handle it properly.
This same issue exists in the EFI firmware on the Whitetip Mountain 2
reference board so it is not specifically a coreboot bug. If this
behavior is fixed in the kernel then this workaround could be removed
since it is in RW firmware.

This patch enhances the armv7 exception handlers in Coreboot and
libpayload to show the correct SP and LR registers from the aborted
context, and also dump a part of the current stack. Since we cannot
access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
any noticeable effect on firmware operation (please correct me if I'm
wrong!).
BUG=None
TEST=Cause a data_abort in Coreboot or depthcharge. Marvel at the
beautifully displayed stack dump that helps you debug the abort.

Trustzone needs to be initialized/disabled both on boot and on wake, so it
needs to be done before ramstage which doesn't run on wake. cpu.c isn't
compiled into romstage and fixing that causes other problems, so the trustzone
