If ramstage caching outside CBMEM is enabled
i.e CONFIG_CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM, then a
helper function to determine the caching region in SMM
should be implemented. Add the same to FSP2.0 driver.
FSP1.1 driver had the same implementation hence copied stage_cache.c.
The SoC code should implement the smm_subregion to provide
the base and size of the caching region within SMM. The fsp/memmap.h
provides the prototype and we will reuse the same from FPS 1.1.

On x86 platforms, google_chromeec_early_init() is used to put the EC
into RO mode when there's a recovery request. This is to avoid training
memory multiple times when the recovery request is through an EC host
event while the EC is running RW code. Under that condition the EC will
be reset (along with the rest of the system) when the kernel verification
happens. This leads to an execessively long recovery path because of the
double reboot performing full memory training each time.
By putting this logic into the verstage program this reduces the
bootblock size on the skylake boards. Additionally, this provides the
the correct logic for all future boards since it's not tied to FSP
nor the mainboard itself. Lastly, this double memory training protection
works only for platforms which verify starting from bootblock. The
platforms which don't start verifying until after romstage need to
have their own calls (such as haswell and baytrail).

The SPI drivers for the various chipsets are not consistent in
their handling of when they are accessible. Coupled with the
unknown ordering of boot_device_init() being called this can
lead to unexpected behavior (probing failures or hangs). Instead
move the act of initializing the SPI flash boot device to when
the various infrastructure requires its usage when it calls
boot_device_rw(). Those platforms utilizing the RW boot device
would need to ensure their SPI drivers are functional and
ready when the call happens.
This further removes any other systems failing to boot as
reported in https://ticket.coreboot.org/issues/67.

It's necessary to call spi_init() prior to calling spi_flash_probe()
such that the SPI drivers can do any work required prior to performing
SPI transactions. It could be argued that the drivers should handle
such situations, however the SPI API implementations seem to assume the
callers ensured spi_init() was called before any SPI transactions.
This fixes systems that failed to boot introduced by [1]. Issue tracked

On many x86 platforms the boot device is SPI which is memory
mapped. However, in order to write to the boot device one needs
to use the SPI api. Therefore, provide a common implementation
of boot_device_rw() which has no mmap() functionality. It only
reads, writes, and erases. This will be used in the existing
infrastructure but in a SPI agnostic way.
Two options are added:
1. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP
2. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY
The former is auto-selected when COMMON_CBFS_SPI_WRAPPER is not
selected. The latter can be used to include the implementation
in the early stages such as bootblock, verstage, and romstage.

thereby also never call elog_init() (through elog_add_event()) which
adds the "System boot" event.
We can assume that any board that configures the eventlog at all

Instead of treating offsets relative to after the header make
the offsets relative to the in-memory mirror buffer. This
simplifies the logic in that all offsets are treated the same.
It also allows one to remove a global variable.

A region_device can be used to represent the in-memory mirror
of the event log. The region_device infrastructure has builtin
bounds checking so there's no need to duplicate that. In addition,
it allows for removing much of the math juggling for the buffer
size, etc.

There's only 2 users of checking if the event buffer is cleared
to the EOL value. Each were passing pointers of the in-memory
mirror while also doing calculations for the size to check. Since
the in-memory mirror is one big buffer the only thing required
to know is the offset to start checking from. The check is always
done through the end of the buffer.

There was a check against the next event offset against
the shrink size in elog_shrink(). However, all calls
to elog_shrink() were conditionalized on the next
event offset exceeding the full threshold. The shrink
size is set to the minimum of the full threshold and
a percentage of the elog region size. Therefore, it's
impossible for the next event offset to be less than
the shrink size because full threshold is always greater
than or equal to the shrink size.

For the elog shrink case we log the number of bytes shrunk
from the event log. However, when clearing the log the
size recorded was the entire region size including the header
as well as the event region space. To be more consistent
mark the clearing event with the number of bytes actually
cleared out (excluding the header size).

Although we have already support for the flash chip N25Q128 there is a
similar type available which has the same geometry and opcodes but
unfortunately a slightly different device type ID. While the already
supported N25Q128 has the ID 0xbb18 this one has the ID 0xba18.
To make both types available in the flash support table, use N25Q128A as
the flash name. This name can be found in the datasheet which can be
found here:

TPM_FW_VER register available on VID 1ae0 devices supports reading in

Let's read 50 bytes at a time to reduce the SPI register read wrapper
overhead, and increase the length limit to 300 bytes to accommodate
longer version strings.
