This allows the one 32bit register to be configured in the
devicetree in the same way that Skylake can be.
i.e. register "lpc_ioe".

This patch ensures PWRMBASE macro name and function to get PWRMBASE
address on APL SoC is aligned with other IA SoC.
PMC_BAR0 -> PCH_PWRM_BASE_ADDRESS
read_pmc_mmio_bar() -> pmc_mmio_regs()
Additionally, make `pmc_mmio_regs` a public function for other IA common
code may need to get access to this function.

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

Everything is wrong here, the Kconfig symbols are only the tip of the
iceberg. Based on Kconfig prompts the SoC code performed pad configu-
rations! I don't see why the person who configures coreboot should have
the board schematics at hand.
As a mitigation, we remove the prompts for UART_DEBUG, which is renamed
to INTEL_LPSS_UART_FOR_CONSOLE (because the former didn't really say
what it's about), and for UART_FOR_CONSOLE in case the former is selec-
ted.

cosolidated into one file and moved to common code CPU car folder.
- exit_car_fsp.S is from APL, DNV soc folder is clubbed into one file
and moved to common CPU car.
- The new file apollolake/fspcar.c is addded to pass tempraminit
parameters.
- Coffee lake Soc uses FSPT to support Intel Security features like
BootGuard verify boot and Measured boot. Add FSP CAR support for CFL
by programming tempraminit parameters and add FSP_T_XIP default if
FSP_CAR is selected.

Add support and enalbe cache-as-ram paging for glk to work around
a cache-as-ram corruption issue. glk executes verstage, romstage,
and FSP-M directly out of cache-as-ram (just like apl). However,
the front end on glk is very agressive about pulling cache lines
into L1I for potential execution. When the snoops hit in the L1D
and the cache lines are dirty the processor writes the line back.
However, there is no backing store for the dirty lines to go. As
such when the line is pulled back in the value is all 0xff's,
corrupting cache-as-ram.
To fix the issue one needs to enable paging with NX (no execute)
permissions which prevents the above actions from happening because
the TLB will indicate that shouldn't be fetched into the instruction
cache since data will be marked no execute.
The generated page tables are added to cbfs and only added to the
COREBOOT cbfs as they are only consumed in the early cache-as-ram
stages.
The page tables generated with:

enumeration is done by ramstage which allocates a new BAR.
- Call spi_init to allow bootblock/verstage to write/erase on flash.

- spi_init needs to run in ramstage to allow write protect to be
disabled for eventlog and NVRAM updates. This needs to be done pretty
early so that any init calls(e.g. mainboard_ec_init) writing to flash
work properly.

The flush L1D to L2 operation was only being used when loading
romstage from bootblock. However, when the FSP-M component is
loaded no code coherency actions are taken. I suspect this is
because the FSP-M component is larger than the 24KiB L1D and
the entry point is early in the image. Thus, when loading
the FSP-M component the earlier part of the image is flushed
out to L2 in the process of loading the latter part of the
component. Also, once verstage is introduced the same
code coherency actions need to be taken as well. Therefore,
position the apollolake code to handle all these cases.

The current Apollolake flow has its code executing out of
cache-as-ram for the pre-DRAM stages. This is different from
past platforms where they were just executing-in-place against
the memory-mapped SPI flash boot media. The implication is
that when cache-as-ram needs to be torn down one needs to be
executing out of DRAM since the act of cache-as-ram going
away means the code disappears out from under the processor.
Therefore load and use the postcar infrastructure to bootstrap
this process for tearing down cache-as-ram and subsequently
loading ramstage.

away. This is because we are in NEM mode, there is no backing store
and a miss in L1 may cause L1D line snoop that gets written back. The
solution is to flush L1D to L2 so snoop guaranteed to hit L2.

in bootblock requiered for serial to be set up.

This is the minimum setup needed to both get cache-as-ram setup and a
C environment working. On apollolake, we only get 32 KiB of data
loaded into an SRAM that is readonly to the main CPU. Due to this
restriction we have to set CAR and a C environment very early on.
