Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.
Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.
Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.
New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.

The feature is used to enable PCI MMIO accesses behind
PCIe links (or bridges) before PCI enumeration has been
completed.
Add the feature for bootblock, verstage and postcar, it
is required with add-on PCIe serial cards for early
console output. It's up to the board specific code to
configure PCIe root port prior to calling console_init()
for this to work.
Remove feature from ramstage, it bypasses any resource
allocations and bus number assignments.
For the moment PCI configuration support before ramstage
is available only on ARCH_X86.
Also switch from device_t to pci_devfn_t.

The H81 chipset is the only non-LP Lynx Point chipset with 6 PCIe root
ports, all others have 8 [1]. The existing PCIe code assumed that all
non-LP chipsets had 8 root ports, which meant that port 6 would not be
considered the last root port on H81, so `root_port_commit_config()`
would not run. Ultimately, while PCIe still worked on H81, all the root
ports would remain enabled, even if disabled in the devicetree.
Also, remove `PCI_DEVICE_ID_INTEL_LYNXPOINT_MOB_DESK_{MIN,MAX}`, as they
are unused, and the MAX constant is incorrect.
Interestingly, this fixes an issue where GRUB is unable to halt the
system.
Tested on an ASRock H81M-HDS. The root ports disabled in the devicetree
do indeed end up disabled.

A very common pattern in drivers is that we need to wait for a condition
to become true (e.g. for a lock bit in a PLL status register to become
set), but we still want to have a maximum timeout before we treat it as
an error. coreboot uses the stopwatch API for this, but it's still a
little verbose for the most simple cases. This patch introduces two new
helper macros that wrap this common application of the stopwatch API in
a single line: wait_ms(XXX, YYY) waits for up to XXX milliseconds to see
if the C condition 'if (YYY)' becomes true. The return value is 0 on
failure (i.e. timeout expires without the condition becoming true) and
the amount of elapsed time on success, so it can be used both in a
boolean context and to log the amount of time waited.
Replace the custom version used in an MTK ADC driver with this new
generic version.

The selfboot function was changed at some point to take a parameter
which meant "check the allocated descriptors to see if they target
regions of real memory."
The region check had to be buried deep in the last step of loading since
that is where those descriptors were created and used.
An issue with the use of the parameter was that it was not possible
for compilers to easily divine whether the check code was used,
and it was hence possible for the code, and its dependencies, to be
compiled in even if never used (which caused problems for the
rampayload code).
Now that bounce buffers are gone, we can hoist the check code
to the outermost level. Further, by creating a selfload_check
and selfload function, we can make it easy for compilers
to discard unused code: if selfload_check is never called, all
the code it uses can be discarded too.

Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also
implement board_reset() as a "full reset" (aka. cold reset) as that
is what was used here for hard_reset().
Drop soc_reset_prepare() thereby, as it was only used for APL. Also,
move the global-reset logic.
We leave some comments to remind us that a system_reset() should
be enough, where a full_reset() is called now (to retain current
behaviour) and looks suspicious.
Note, as no global_reset() is implemented for Denverton-NS, we halt
there now instead of issuing a non-global reset. This seems safer;
a non-global reset might result in a reset loop.

Bounce buffers used to be used in those cases where the payload
might overlap coreboot.
Bounce buffers are a problem for rampayloads as they need malloc.
They are also an artifact of our x86 past before we had relocatable
ramstage; only x86, out of the 5 architectures we support, needs them;
currently they only seem to matter on the following chipsets:
src/northbridge/amd/amdfam10/Kconfig
src/northbridge/amd/lx/Kconfig
src/northbridge/via/vx900/Kconfig
src/soc/intel/fsp_baytrail/Kconfig
src/soc/intel/fsp_broadwell_de/Kconfig
The first three are obsolete or at least could be changed
to avoid the need to have bounce buffers.
The last two should change to no longer need them.
In any event they can be fixed or pegged to a release which supports
them.
For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the
value needed in 1999 for the 32-bit Linux kernel, the original ramstage)
to 0xe00000 (14 Mib) which will put the non-relocatable x86
ramstage out of the way of any reasonable payload until we can
get rid of it for good.
14 MiB was chosen after some discussion, but it does fit well:
o Fits in the 16 MiB cacheable range coreboot sets up by default
o Most small payloads are well under 14 MiB (even kernels!)
o Most large payloads get loaded at 16 MiB (especially kernels!)
With this change in place coreboot correctly still loads a bzImage payload.
Werner reports that the 0xe00000 setting works on his broadwell systems.
