The current EFI video driver only works when running in the stub. In that
case the stub calls boot services (before jumping to U-Boot proper) and
copies the graphics info over to the efi table. This is necessary because
the stub exits boot services before jumping to U-Boot.
The app maintains access to boot services throughout its life, so does not
need to do this. Update the driver to support calling boot services
directly.
Enable video output for the app. Note that this uses the

not what we want for SDRAM.
* The call to mtrr_add_request() is not guaranteed to have its size

When switching to kernel.org x86_64 gcc 11.1.0 toolchain, u-boot.rom
built from qemu-x86_defconfig no longer boots anymore. Investigation
shows that U-Boot fails at a very early stage during the boot process,
in fdtdec_prepare_fdt() where fdt_check_header() complains that there
is not a valid device tree found at gd->fdt_blob which points to _end.
Now _end points to an allocated section .note.gnu.property which of
course is wrong.
This issue is however not seen when using the default Ubuntu 20.04 gnu
toolchain (gcc 9.3.0 with binutils 2.34). Further investigation shows
that it is caused by a behavior change of binutils v2.36 which is part
of the kernel.org gcc 11.1.0 toolchain, via the following commit:
939b95c77bf2 ("Linux/x86: Configure gas with --enable-x86-used-note by default")
In fact, there was already a regression bug report [1] for binutils two
months ago, but the binutils folks did not think it is a bug :(
To resolve this, there are several options:
* pass -Wa,-mx86-used-note=no to gas
* pass -R .note.gnu.property to objcopy
* discard the section in the linker script
Linux kernel uses the discard way [2], so let's do the same for U-Boot.

This commit does the same thing as Linux commit 33def8498fdd.
Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

The current usage of the variable CFLAGS_NON_EFI on the x86 architecture
deviates from other architectures.
Variable CFLAGS_NON_EFI is the list of compiler flags to be removed when
building UEFI applications. It is not a list of flags to be added anywhere.

We move qfw into its own uclass and split the PIO functions into a
specific driver for that uclass. The PIO driver is selected in the
qemu-x86 board config (this covers x86 and x86_64).
include/qfw.h is cleaned up and documentation added.

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)

The _SUPPORT suffix is from an earlier time and interferes with use of
the CONFIG_IS_ENABLED() macro. Rename the option to drop the suffix.
Tidy up the TODO that prompted this.

When booting from coreboot there is no need to notify the FSP of anything,
since coreboot has already done it. Nor it is possible, since the FSP
details are not provided by coreboot.
Skip it in this case.

When booting from coreboot the FSP video information is no-longer
available. Enable the coreboot driver so that we can get some sort of
display in this case.

At present the debug UART is only set up in SPL, on the assumption that
the boot flow will always pass through there. When booting from coreboot,
SPL is not used, so the debug UART is not available.
Move the code into a common place so that it can be used in U-Boot proper
also. Add the required init to start_from_spl.S as well.

This driver cannot work when booted from coreboot, since the FSP
information is not available. Disable it in that case, so that the
coreboot video driver can be used instead.

Quite a few new tag types have been added over the years. Bring these into
U-Boot so that all required tags can be parsed.
Add a proper comment to struct sysinfo_t while we are here, since many of
the meanings are not obvious.
