mtk_init_mcu uses DRAM_DMA section as CBFS buffer.
The change "mediatek/mt8183: Remove DRAM_DMA section" is reverted
for using mtk_init_mcu.
On mt8173 and mt8192, this region is used by DMA hardware and is
marked as non-cacheable resource. On mt8183, this region is reserved
as CBFS buffer, so it is not necessary to be marked as non-cacheable
resource.

This patch addresses the same problem as CB:48429, but hopefully this
time correctly. Since the mcache is not guaranteed to be available on
the first CBFS lookup for some special cases, we can no longer treat it
as a one-time fire-and-forget initialization. Instead, we test
cbd->mcache_size to check if the mcache has been initialized yet, and
keep trying on every lookup if we don't find it the first time.
Since the mcache is a hard requirement for TOCTOU safety, also make it
more clear in Kconfig that configurations known to do CBFS accesses
before CBMEM init are incompatbile with that, and make sure we die()
rather than do something unsafe if there's a case that Kconfig didn't
catch.

This change reorganizes FMAP for volteer to make use of the lower
16MiB of the SPI flash for RW_SECTION_A and RW_MISC in addition to
RW_LEGACY. This is now possible because TGL supports memory mapping of
BIOS region greater than 16MiB.
Following changes are made in chromeos.fmd as part of this:
1. Move RW_SECTION_A and RW_MISC to lower 16MiB.
2. Reduce size of RW_LEGACY to 2MiB since we longer need to use it as
a placeholder in the lower half of the SPI flash.
3. Reduce size of RW_ELOG to 4KiB as coreboot does not support a
larger region for ELOG.
4. Increase WP_RO to 8MiB to allow larger space for firmware
screens. GBB size is thus increased to 448KiB.

This change allows configuring the General Purpose
Memory Range(GPMR) register in BIOS to set up the decoding in DMI.
This driver provides the following functionality:
1. Add a helper function dmi_enable_gpmr which takes as input base,
limit and destination ID to configure in general purpose memory range
registers and then set the GPMR registers in the next available
free GMPR and enable the decoding.
2. Add helper function get_available_gpmr which returns available free
GPMR.
3. This helper function can be utilized by the fast SPI driver to
configure the window for the extended BIOS region.

This change adds details about the memory map windows to translate
addresses between SPI flash space and host address space to coreboot
tables. This is useful for payloads to setup the translation using the
decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.
`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

This change reserves the window used for extended BIOS decoding as a
fixed MMIO resource using read_resources callback in systemagent
driver. This ensures that the resource allocator does not allocate
from this window.
Additionally, this window is also marked as fixed memory region in
_CRS for PNP0C02 device.
