Lower 20bits of TOLUD register include 19 reserved bits and 1 lock
bit. If lock bit is set, then northbridge.asl was reporting the base
address of low MMIO incorrectly i.e. off by 1. This resulted in Linux
kernel complaining that the MMIO window allocated to the device at the
base of low MMIO is incorrect:
pci 0000:00:1c.0: can't claim BAR 8 [mem 0x7fc00000-0x7fcfffff]: no compatible brw
pci 0000:00:1c.0: [mem 0x7fc00000-0x7fcfffff] clipped to [mem 0x7fc00001-0x7fcfff]
pci 0000:00:1c.0: bridge window [mem 0x7fc00001-0x7fcfffff]
This change masks the lower 20 bits of TOLUD register when exposing it
in the ACPI tables to ensure that the base address of low MMIO region
is reported correctly.
TEST=Verified that kernel dmesg no longer complains about the BAR at
base of low MMIO.

Mainboard specific dock-init mechanism introduced
https://review.coreboot.org/c/coreboot/+/36093 works on most boards,
but https://ticket.coreboot.org/issues/256 shows that some boards
(e.g. x201 and t410) need communication with h8 EC to enable or
disable dock, (in dock_connect() and dock_disconnect() respectively)
so they must be done after the h8 EC is brought up, which is not
garanteed in the above mainboard specific dock-init mechanism.
This time, a hook function h8_mb_init() will be called at the end of
h8_enable(). (in place of the ancient h8_mainboard_init_dock() removed
in CB:36093) Its default implementation is a weak empty function, but
could be overrided with a strong one for boards needing to perform
actions which should be done after h8 EC is brought up.
This should fix the regression detected in

This change adds a helper function espi_setup() which allows SoCs to
configure connection to slave. Most of the configuration is dependent
upon mainboard settings in espi_config done as part of the device
tree. The general flow for setup involves the following steps:
1. Set initial configuration (lowest operating frequency and single mode).
2. Perform in-band reset and set initial configuration since the
settings would be lost by the reset.
3. Read slave capabilities.
4. Set slave configuration based on mainboard settings.
5. Perform eSPI host controller configuration to match the slave
configuration and set polarities for VW interrupts.
6. Perform VW channel setup and deassert PLTRST#.
7. Perform peripheral channel setup.
8. Perform OOB channel setup.
9. Perform flash channel setup.
10. Enable subtractive decoding if requested by mainboard.
