The PCI config space of the SMBus device has a secondary mapping as an
ACPIMMIO bank. Since the PCI device is on bus 0, it's already available
early in boot after the enable_pci_mmconf call, so there's no need to
use the ACPIMMIO mapping instead of the PCI config space mapping.
Verstage on PSP could theoretically access the PCI config space via the
0xcf8/0xcfc register pair, but since verstage on PSP doesn't have the
ACPIMMIO mapping anyway, we won't loose any functionality here.

Hence, the idea here is to maintain a 32MB SPI Flash layout across all

BOARD_ROMSIZE_KB_65536 config for adding padding at the end of the

Currently, to enable/disable LTE based on fw_config on nissa, we have
two sets of GPIOs: lte_enable_pads and lte_disable_pads. This was to
prevent the SAR interrupt pin GPP_H19 from floating for the short period
of time between enabling it in gpio.c and disabling it in fw_config.c
(see CB:64270 for more details).
With the new pad-based GPIO overrides (CB:64712), this is no longer an
issue since the gpio.c and fw_config.c overrides are applied at the same
time. So simplify the LTE GPIO configuration by enabling all the LTE
pins in the variant gpio.c, then disabling them in fw_config.c if
needed.

Starting vboot earlier in bootblock instead of romstage is usually
preferred (smaller root of trust, among other things). Therefore
unselect VBOOT_STARTS_IN_ROMSTAGE for broadwell. Also remove the unused
BROADWELL_VBOOT_IN_BOOTBLOCK option.

The I2C config was unnecessarily placed in the overridetree. As we
prepare for fanout, this is going to cause unnecessary noisy changes.
Move the I2C config to the devicetree to avoid this.

The PCIe spec explicitly states that the bottom-two bits of the next
offset are reserved for future use and should be masked. We can also
change the loop condition to avoid wrong offsets below 0x100 (exten-
ded capabilities always reside in the extended config space).
The whole patch series was tested on Google Samus and keeps the L1ss
configuration of the WiFi device in tact.

Add some inline functions for the bit-wise operations, change the loop
body to an if-bail-out style and remove stateful variables.

Keeping these checks in generic code seems rather dangerous.
In theory, it could lead to endless loops even for compliant
devices, if we accidentally detect arbitrary register contents
as capability and use them as a pointer to another one. Not
to forget that the register reads can have side effects.
All users of this `cafe` have been converted to use
pciexp_find_ext_vendor_cap().

We have this quirk in our tree since the introduction of L1-substate
support[1]. The way we searched for this capability was rather crude:
We simply assumed that it would show up in the first data word of
another capability.
As it turned out that it is actually a proper vendor-specific capa-
bility that we are looking for, we can drop some of the mystic code.
This was confirmed to work on the device that was originally used
during development, Google/Samus.

Move the `offset` parameter into pciexp_find_extended_cap(). If it's
called with `0`, we start a new search. If it's an existing offset,
we continue the search.
This makes it easier to search for multiple occurences of a capa-
bility in a single loop.
