This change drops the check for IS_TOP_ALIGNED_ADDRESS() before
setting offset to 0 in cbfstool_convert_fsp(). If the user provides a
baseaddress to relocate the FSP to, then the offset should be set to 0
since there is no requirement on where the file ends up in cbfs. This
allows the user to relocate the FSP to an address in lower DRAM.

This reverts commit 9ff4029db9.
Pulling the toplevel Makefile into a tiny one has all sorts of side
effects. For instance, the toplevel (random) .config is also included
so the results depend on the board that is selected there. What finally
broke it is a line that is unconditionally printed for AMD Picasso
boards resulting in lots of lines like this:
skipping LENOVO_W520 because we're missing compilers for \
(Adding PSP c7ce61492157d3237f679c4a40a08b79 \
.../coreboot/3rdparty/amd_blobs/picasso/PSP/PspBootLoader_prod_RV.sbin)
While both issues, the random .config and amd/picasso, could be worked
around easily, it seems hard to predict what other pitfalls are lurking
in the Makefile inclusion. Also, the problem solved by its inclusion
can be fixed by a much simpler `make .xcompile`.

The GCC 10 GNAT toolchain uses a new exception handler ABI, so older
GNAT cannot be built with GCC 10. This patch backports the new
exception handler in libgnat to make GNAT able to be built.
The libgnat patch doesn't remove the old exception handler, so it can
still be built with older compilers.
The cross toolchain can now be built with GCC 10.1.0 in Arch Linux
(with the latest IASL in CB:38907 that can be built in Arch), and the
toolchain can build a working coreboot image with libgfxinit for HP
EliteBook 2560p.
The original and patched crossgcc built with Debian 10.4 GCC 8.3.0,
and the patched crossgcc built with Arch GCC 10.1.0 generate identical
coreboot images with `make BUILD_TIMELESS=1`.

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 LPDDR4x
memory used in memory down configurations on Intel Tiger Lake (TGL)
and Jasper Lake (JSL) based platforms. These tools generate SPDs
following JESD209-4C specification and Intel recommendations (doc
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 LPDDR4x
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.

This change adds support to sconfig for generating the firmware

In addition these fields and options can be used to probe for a device
and have that device be disabled if it is not found at boot time.
New tokens:
fw_config: top level token, table can be defined before chips
field: define field in the mask with the start and end bits
option: define option in a field with the value of the field
probe: indicate that a device should probe by field and option
Example:
fw_config
field FEATURE 0 0
option DISABLE 0
option ENABLE 1
end
end
chip drivers/generic/feature
device generic 0 on
probe FEATURE ENABLE
end
end
Variants can add new fields and add new options to existing fields in
overridetree.cb but cannot redefine an existing option.
Devices can have multiple probe tokens, and the device will be considered
to be found if any of them return true.
The output from defining this field are:
1) the various fields and options will be added as macro constants to
static.h and can be used by fw_config for probing.
2) the probe entries will result in a list of fields/options to probe
that is added to the resulting struct device and handled by coreboot.

As requested by Stefan.
For nvramtool some of these lines are part of a paragraph of fluff,
so manual processing was easier than adapting the script used for
the rest of the tree.

This is all code coming from the outside, so let's keep these files
untouched as much as possible.
A couple of files is added to the list by name because their license,
while free, can't be properly modelled in SPDX:
- lzmadecode is (LGPL OR CPL) WITH special-exception
- stack.c and start16 are some weird (but free) US Gov't license grant
- two XGI related files have "BSD except for Linux, where it's GPL"

chip_instance structure currently uses a ref_count to determine how
many devices hold reference to that instance. If the count drops to
zero, then it is assumed that the chip instance is a duplicate in
override tree and has a similar instance that is already overriden in
base device tree.
ref_count is currently decremented whenever a device in override tree
matches the one in base device tree and the registers from the
override tree instance are copied over to the base tree instance. On
the other hand, if a device in override tree does not match any device
in base tree under a given parent, then the device is added to base
tree and all the devices in its subtree that hold pointers to its
parent chip instance are updated to point to the parent's chip
instance in base tree. This is done as part of update_chip_pointers.
However, there are a couple of issues that this suffers from:
a) If a device is present only in override tree and it does not have
its own chip (i.e. pointing to parent's chip instance), then it
results in sconfig emiiting parent's chip instance (which can be the
SoC chip instance) in static.c even though it is unused. This is
because update_chip_pointers() does not call delete_chip_instance()
before reassigning the chip instance pointer.
b) If a device is added under root device only in the override tree
and it does not have its own chip instance (i.e. uses SoC chip
instance), then it results in sconfig emitting a copy of the SoC chip
instance and setting that as chip_ops for this new device in the
override tree.
In order to fix the above issues, this change drops the ref_count
field from chip_instance structure and instead adds a forwarding
pointer `base_chip_instance`. This is setup as per the following
rules:
1. If the instance belongs to base devicetree, base_chip_instance is
set to NULL.
2. If the instance belongs to override tree, then it is set to its
corresponding chip instance in base tree (if present), else set to
NULL.
State of base_chip_instance is then used when emitting chips and
devices using the following rules:
1. If a chip_instance has non-NULL base_chip_instance, then that chip
instance is not emitted to static.c
2. When emitting chip_ops for a device, base_chip_instance is used to
determine the correct chip instance name to emit.
BUG=b:155549176
TEST=Verified that the static.c file generated for base/override tree
combination is correct when new devices without chips are added only
to override tree.

This change moves the assignment of id for chip instance from
new_chip_instance() to emit_chips(). This is similar to the previous
change for moving dev id assignment to happen much later.
This ensures that the same ID gets assigned to a chip when adding
support for device trees which makes it easier to compare static.c
files.

This change drops the id field from struct device as used by
sconfig. It was primarily used for generating unique device names. This
was maintained within device structure so that the order in which the
device tree entries were parsed is clear. Since the ids are assigned
in parsing order, it is problematic when a device is moved from base
devicetree to override tree. The entire parsing order changes which
makes it really difficult to compare what really changed in static.c
file.
By moving the dev name assignment to happen later when doing pass0 of
static.c generation, the difference in static.c file is minimized when
adding support for override trees.
