The purpose of pci_early_bridge_init() is to temporarily configure
PCIe rootport (or PCI bridge) on bus 0 to configure PCI device BARs
on the secondary bus. Currently used and tested only with UART_OXPCIE.
Since those BARs do not reset on stage changes, it is not necessary
to redo those steps for verstage or postcar. Note that the option
does not really work with many of the later platforms where PCIe
pins/links/lanes are configured late in FSP-M or similar blob.

Currently, configuring and reviewing DPTF parameters is difficult
because DPTF tables and methods are defined in static ASL files, and are
littered with #ifdefs which both define parameters and influence
behavior (e.g., whether a method is included or not). This patch train
is an effort to bring DPTF support to our ACPI DSDT/SSDT generation
framework.
This first patch is very minimal, and includes only creation of the
DPTF device (in the DSDT).

ALIB function 1 needs to be called every time there is a change in
AC/DC state of the system. This change adds a wrapper method that can
be called by PNOT (method to notify system power state change) to
report to ALIB that system power state has changed i.e. AC <-> DC.
Additionally, this change drops the call to ALIB from _INI method
since the PWRS object might not be initialized correctly at that
point. Instead EC makes a call to PNOT when PWRS is initialized.
This wrapper also fixes the value of power state being passed into
ALIB. ALIB expects 0 = AC and 1 = DC. On the other hand, PWRS reports
1 as AC and 0 as DC. WAL1() takes care of inverting the PWRS state
before passing into ALIB.

This change updates memlayout.ld for Picasso to place all early
stages (bootblock, romstage, FSP-M, verstage) and data buffers (vboot
workbuf, APOB, preram-cbmem console, timestamp, early BSP stack) at
the bottom of DRAM starting at 32MiB. This uses static allocation for
most components by defining Kconfig variables for base and size. It
relies on the linker to complain if any of the assumptions are broken.
This also allows romstage to use linker symbols for
_early_reserved_dram and _eearly_reserved_dram to store information in
CBMEM about the early DRAM usage by coreboot before ramstage starts
execution. This allows ramstage to reserve this memory region in BIOS
tables so that S3 resume can reuse the same space without corrupting
OS memory.

The current test framework builds the test code without any warnings at
all, which isn't great -- we have already slipped in some cases of
non-void functions not returning a defined value, for example. It would
likely be overkill to try to use all the same warnings we use for normal
coreboot code (e.g. some stuff like -Wmissing-prototypes makes cmocka's
__wrap_xxx() mock functions unnecessarily cumbersome to work with, and
other things like -Wvla may be appropriate for firmware but is probably
too aggressive for some simple test code). Therefore, let's just add
some of the stuff that points out the most obvious errors.
