To support the new CONFIG_CBFS_VERIFICATION feature, cbfstool needs to
update the metadata hash embedded in the bootblock code every time it
adds or removes a CBFS file. This can lead to problems on certain
platforms where the bootblock needs to be specially wrapped in some
platform-specific data structure so that the platform's masked ROM can
recognize it. If that data structure contains any form of hash or
signature of the bootblock code that is checked on every boot, it will
no longer match if cbfstool modifies it after the fact.
In general, we should always try to disable these kinds of features
where possible (they're not super useful anyway). But for platforms
where the hardware simply doesn't allow that, this patch introduces the
concept of "platform fixups" to cbfstool. Whenever cbfstool finds a
metadata hash anchor in a CBFS image, it will run all built-in "fixup
probe" functions on that bootblock to check if it can recognize it as
the wrapper format for a platform known to have such an issue. If so, it
will register a corresponding fixup function that will run whenever it
tries to write back modified data to that bootblock. The function can
then modify any platform-specific headers as necessary.
As first supported platform, this patch adds a fixup for Qualcomm
platforms (specifically the header format used by sc7180), which
recalculates the bootblock body hash originally added by
util/qualcomm/createxbl.py.
(Note that this feature is not intended to support platform-specific
signature schemes like BootGuard directly in cbfstool. For anything that
requires an actual secret key, it should be okay if the user needs to
run a platform-specific signing tool on the final CBFS image before
flashing. This feature is intended for the normal unsigned case (which
on some platforms may be implemented as signing with a well-known key)
so that on a board that is not "locked down" in any way the normal use
case of manipulating an image with cbfstool and then directly flashing
the output file stays working with CONFIG_CBFS_VERIFICATION.)

This patch adds support for the new CONFIG_CBFS_VERIFICATION feature to
cbfstool. When CBFS verification is enabled, cbfstool must automatically
add a hash attribute to every CBFS file it adds (with a handful of
exceptions like bootblock and "header" pseudofiles that are never read
by coreboot code itself). It must also automatically update the metadata
hash that is embedded in the bootblock code. It will automatically find
the metadata hash by scanning the bootblock for its magic number and use
its presence to auto-detect whether CBFS verification is enabled for an
image (and which hash algorithm to use).

The `q35-alpine.cfg` adds a lot of PCIe devices to resemble the
topology inside an Intel Alpine Ridge Thunderbolt controller.
By no means could this be detected as such a controller. But
having a real-world example of such a topology can help to
test the allocator and other algorithms on a deeper tree.
It adds two levels of PCIe switches (`alpine-root` and
`alpine-1`), and two endpoints (a `pci-testdev` and an xHCI
controller).
It can be added to the default `q35-base.cfg` config, e.g.
with:
$ make qemu QEMU_EXTRA_CFGS=util/qemu/q35-alpine.cfg

CB:49896 added support in `intel_microcode_find()` to cache the found
microcode for faster subsequent accesses. This works okay when the
function succeeds in finding the microcode on BSP. However, if for any
reason, `cpu_microcode_blob.bin` does not contain a valid microcode
for the given processor, then the logic ends up attempting to find
microcode again and again every time it is called (because
`ucode_updates` is set to NULL on failed find, thus retriggering the
whole find sequence every time). This leads to a weird race condition
when multiple APs are running in parallel and executing this
function.
A snippet of the issues observed in the scenario described above:
```
...
microcode: Update skipped, already up-to-date
...
Microcode header corrupted!
...
```
1. AP reports that microcode update is being skipped since the current
version matches the version in CBFS (even though there is no matching
microcode update in CBFS).
2. AP reports microcode header is corrupted because it thinks that the
data size reported in the microcode is larger than the file read from
CBFS.
Above issues occur because each time an AP calls
`intel_microcode_find()`, it might end up seeing some intermittent
state of `ucode_updates` and taking incorrect action.
This change fixes this race condition by separating the logic for
finding microcode into an internal function `find_cbfs_microcode()`
and maintaining the caching logic in `intel_microcode_find()` using a
boolean flag `microcode_checked`.
BUG=b:182232187
TEST=Verified that `intel_microcode_find()` no longer makes repeated
attempts to find microcode from CBFS if it failed the first time.

Also switch to `bootblock_mainboard_early_init` to configure the pads in
early bootblock before console initialization, to make the console work
as early as possible. The board does not do any other gpio configuration
in bootblock, so this should not influence behaviour in a negative way
(e.g. breaking overrides).

Configuring touch controllers to use edge-triggered interrupts is not
recommended as it is very easy to lose an edge when kernel drivers
disable the interrupt for one reason or another, and recovering from
this condition requires workarounds in the kernel.
Unfortunately the example setting up a touchpad used edge-triggered
interrupts, and this set up has been propagating through the boards.
Let's switch the example to use level interrupts instead.
