It seems that GCC's LTO doesn't like the way we implement
DECLARE_OPTIONAL_REGION(). This patch changes it so that rather than
having a normal DECLARE_REGION() in <symbols.h> and then an extra
DECLARE_OPTIONAL_REGION() in the C file using it, you just say
DECLARE_OPTIONAL_REGION() directly in <symbols.h> (in place and instead
of the usual DECLARE_REGION()). This basically looks the same way in the
resulting object file but somehow LTO seems to like it better.

Removing entry covering root region leads to situation where
num_entries counter is set to 0. This counter is further decremented
in function obtaining address to last entry (see root_last_entry()).
Such negative number may be further used as an index to the table.
Current implementation may lead to crash, when user removes last entry
with imd_entry_remove() and then calls for example imd_entry_add().

One of the checks inside imdr_recover() was written with the
assumption that imdr limit is always aligned to LIMIT_ALIGN. This is
true only for large allocations, thus may fail for small regions.
It's not necessary to check if root_pointer is under the limit, since
this is implicitly verified by imdr_get_root_pointer().

This reverts commit 81066b7ce7.
Reason for revert: The hang observed when not exposing the reset GPIOs was root caused to zork sharing the same I2C bus between touchscreen and touchpad and interleaving of messages during probe which resulted in incorrect information returned back by touchscreen firmware. Exposing the reset GPIO changed the timing of probe and hence helped workaround the hang issue. The touchscreen driver is now fixed to perform I2C transactions in a single transfer and so the hang is no longer observed when reset GPIO isn't exposed.

Serial Presence Detect (SPD) data for memory modules is used by Memory
Reference Code (MRC) for training the memory. This SPD data is
typically obtained from part vendors but has to be massaged to format
it correctly as per JEDEC and MRC expectations. There have been
numerous times in the past where the SPD data used is not always
correct.
In order to reduce the manual effort of creating SPDs and generating
DRAM IDs, this change adds tools for generating SPD files for DDR4
memory used in memory down configurations on Intel Tiger Lake (TGL)
based platforms. These tools generate SPDs following JESD79-4C and
Jedec "4.1.2.L-5 R29 v103" specification.
Two tools are provided:
* gen_spd.go: Generates de-duplicated SPD files using a global memory
part list provided by the mainboard in JSON format. Additionally,
generates a SPD manifest file (in CSV format) with information about
what memory part from the global list uses which of the generated
SPD files.
* gen_part_id.go: Allocates DRAM strap IDs for different DDR4
memory parts used by the board. Takes as input list of memory parts
used by the board (with one memory part on each line) and the SPD
manifest file generated by gen_spd.go. Generates Makefile.inc for
integrating the generated SPD files in the coreboot build.

Instead of halting if the vboot workbuf is not passed to coreboot by the
PSP, reset and reboot into recovery mode.
This process is made more difficult because if the workbuf isn't
available, we can't reboot directly into recovery - the workbuf is
needed for that process to be done through the regular calls, and we
don't want to go around the vboot API and just write into VBNV directly.
To overcome this, we set a CMOS flag, and reset the system.
PSP_verstage checks for this flag so it will update VBNV and reset the
system after generating the workbuf.

TEST=Simulate the workbuf not being present and verify the reboot
process.

Create two new functions to fetch mrc_cache data (replacing
mrc_cache_get_current):
- mrc_cache_load_current: fetches the mrc_cache data and drops it into
the given buffer. This is useful for ARM platforms where the mmap
operation is very expensive.
- mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a
given buffer. This is useful for platforms where the mmap operation
is a no-op (like x86 platforms). As the name mentions, we are not
freeing the memory that we allocated with the mmap, so it is the
caller's responsibility to do so.
Additionally, we are replacing mrc_cache_latest with
mrc_cache_get_latest_slot_info, which does not check the validity of
the data when retrieving the current mrc_cache slot. This allows the
caller some flexibility in deciding where they want the mrc_cache data
stored (either in an mmaped region or at a given address).
