ce1dc0cc17 x86: efi: Update efi_get_next_mem_desc() to avoid needing a map
At present this function requires a pointer to struct efi_entry_memmap
but the only field used in there is the desc_size. We want to be able
to use it from the app, so update it to use desc_size directly.

40b172314b x86: efi: Show the system-table revision
Show the revision of this table as it can be important.

Also update the 'efi table' entry to show the actual address of the EFI
table rather than our table that points to it. This saves a step and the
intermediate table has nothing else in it.

567dfef2fe x86: Show some EFI info with the bdinfo command
It is useful to see some basic EFI info with the command as it forms part
of the information about a board.

Add a hook for this and show the table address as a start.

While here, fix an invalid cast in setup_efi_info(). Note that this
function is using a data structure defined by Linux so we cannot change
it. Also note that ulong is used since this is the standard in U-Boot
(>6k uses), despite there being quite a bit of the more verbose uintptr_t
(930 uses).

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

4021ee6388 x86: Rename board_final_cleanup() to board_final_init()
This function sounds like something that is called when U-Boot is about to
jump to Linux. In fact it is an init function.

Rename it to reduce confusion.

d3d6531866 efi: payload: only init usb if necessary
Up until now the call to initialize the USB subsystem was hardcoded
for U-Boot running as an EFI payload. This was used to enable the
use of a USB keyboard in the U-Boot shell. However not all boards
might need this functionality. As initializing the USB subsystem can
take a considerable amount of time (several seconds on some boards),
we now initialize the USB subsystem only if U-Boot is configured to
use USB keyboards.

1fdeacd32c x86: zimage: Support booting Linux kernel from an EFI payload
At present Linux kernel loaded from U-Boot as an EFI payload does
not boot. This fills in kernel's boot params structure with the
required critical EFI information like system table address and
memory map stuff so that kernel can obtain essential data like
runtime services and ACPI table to boot.

With this patch, now U-Boot as an EFI payload becomes much more
practical: it is another option of kernel bootloader, ie, can be
a replacement for grub.

1ab2c01087 x86: efi-x86_payload: Enable usb keyboard during boot
For boards that don't route serial port pins out, it's quite common
to attach a USB keyboard as the input device, along with a monitor.
However USB is not automatically started in the generic efi payload
codes. This uses a payload specific last_stage_init() to start the
USB bus, so that a USB keyboard can be used on the U-Boot shell.

4f1dacd43f x86: efi: Refactor the directory of EFI app and payload support
At present the EFI application and payload support codes in the x86
directory is distributed in a hybrid way. For example, the Kconfig
options for both app and payload are in arch/x86/lib/efi/Kconfig,
but the source codes in the same directory get built only for
CONFIG_EFI_STUB.

This refactors the codes by consolidating all the EFI support codes
into arch/x86/cpu/efi, just like other x86 targets.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

76d1d02fd2 board_f: x86: Use checkcpu() for CPU init
At present we misuse print_cpuinfo() do so CPU init on x86. This is done
because it is the next available call after the console is enabled. But
several arches use checkcpu() instead. Despite the horrible name (which
we can fix), it seems a better choice.

Adjust the various x86 CPU implementations to move their init code into
checkcpu() and use print_cpuinfo() only for printing CPU info.
