5d94cbd1dc scripts: Makefile.lib: generate dsdt_generated.c instead of dsdt.c
There is a conflict between the static file
lib/acpi/dsdt.c and the file dsdt.c generated
dynamicaly by scripts/Makefile.lib. When a
mrproper is done, the static file dsdt.c is
removed. If a build with acpi enabled is
launched after, the following error is raised:

  CC      lib/acpi/acpi_table.o
make[2]: *** No rule to make target 'lib/acpi/dsdt.asl', needed by 'lib/acpi/dsdt.c'.  Stop.
scripts/Makefile.build:394: recipe for target 'lib/acpi' failed

To avoid such error, the generated file is named
dsdt_generated.c instead of dstdt.c.

9539738509 treewide: Use OF_REAL instead of !OF_PLATDATA
Now that we have a 'positive' Kconfig option, use this instead of the
negative one, which is harder to understand.

50cf68c728 x86: coral: Allow booting from coreboot
Set up coral so that it can boot from coreboot, even though it is a
bare-metal build. This helps with testing since the same image can be used
in both cases.

80a4570c99 x86: coral: Show memory config and SKU ID on startup
Provide the model information through sysinfo so that it shows up on
boot. For memconfig 4 pins are provided, for 16 combinations. For SKU
ID there are two options:

   - two pins provided in a ternary arrangement, for 9 combinations.
   - reading from the EC

Add a binding doc and drop the unused #defines as well.

Example:

   U-Boot 2021.01-rc5

   CPU:   Intel(R) Celeron(R) CPU N3450 @ 1.10GHz
   DRAM:  3.9 GiB
   MMC:   sdmmc@1b,0: 1, emmc@1c,0: 2
   Video: 1024x768x32 @ b0000000
   Model: Google Coral (memconfig 5, SKU 3)

This depends on the GPIO series:

These GPIOs are needed later if Chromium OS verified boot is running,
so free them after use.

2764cf5e97 x86: coral: Add sysinfo ops
These ops are missing at present which is not permitted. Add an empty
operation struct.

Note: If the uclass requires operations then the drivers should provide
them. Otherwise, checking for missing operations must be done in every
uclass operation, so it adds to code size.

8b842be10c x86: apl: Reduce size for TPL
Update various drivers to use of_match_ptr() and to avoid including debug
strings in TPL. Omit the WiFi driver entirely, since it is not used in
TPL.

This reduces the TPL binary size by about 608 bytes.

3a8ee3df83 board: Rename uclass to sysinfo
This uclass is intended to provide a way to obtain information about a
U-Boot board. But the concept of a U-Boot 'board' is the whole system,
not just one circuit board, meaning that 'board' is something of a
misnomer for this uclass.

In addition, the name 'board' is a bit overused in U-Boot and we want to
use the same uclass to provide SMBIOS information.

The obvious name is 'system' but that is so vague as to be meaningless.
Use 'sysinfo' instead, since this uclass is aimed at providing information
on the system.

Rename everything accordingly.

Note: Due to the patch delta caused by the symbol renames, this patch
shows some renamed files as being deleted in one place and created in
another.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.
