Since u-boot does not implement Ready to Boot event,
these measurements are performed when efi_start_image() is called.
TCG spec also requires to measure "Calling EFI Application from
Boot Option" for each boot attempt, and "Returning from EFI
Application from Boot Option" if a boot device returns control
back to the Boot Manager.

U-Boot mostly uses hex for value input, largely because addresses are much
easier to understand in hex.
But in some cases a decimal value is requested, such as where the value is
small or hex does not make sense in the context. In these cases it is
sometimes useful to be able to provide a hex value in any case, if only to
resolve any ambiguity.
Add this functionality, for increased flexibility.

BIOS Release Date must be in format mm/dd/yyyy and must be release date.
U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is
generated from current build timestamp.
Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is
better approximation of U-Boot release date than current build timestamp.
Current U-Boot versioning is in format yyyy.mm so as a day choose 01.
Some operating systems are using BIOS Release Date for detecting when was
SMBIOS table filled or if it could support some feature (e.g. BIOS from
1990 cannot support features invented in 2000). So this change also ensures
that recompiling U-Boot from same sources but in different year does not
change behavior of some operating systems.

so remove it from global autogenerated files and also from Makefile.

Although U-Boot supports capsule update on-disk, it's lack of support for
SetVariable at runtime prevents applications like fwupd from using it.
In order to perform the capsule update on-disk the spec says that the OS
must copy the capsule to the \EFI\UpdateCapsule directory and set a bit in
the OsIndications variable. The firmware then checks for the
EFI_OS_INDICATIONS_FILE_CAPSULE_DELIVERY_SUPPORTED bit in OsIndications
variable, which is set by the submitter to trigger processing of the
capsule on the next reboot.
Let's add a config option which ignores the bit and just relies on the
capsule being present. Since U-Boot deletes the capsule while processing
it, we won't end up applying it multiple times.
Note that this is allowed for all capsules. In the future, once
authenticated capsules are fully supported, we can limit the functionality
to those only.

"A specific updatable hardware firmware store must be represented by

This is not the case for us, since both of our FMP protocols can be
installed at the same time because they are controlled by a single
'dfu_alt_info' env variable.
So make the config options depend on each other and allow the user to
install one of them at any given time. If we fix the meta-data provided
by the 'dfu_alt_info' in the future, to hint about the capsule type
(fit or raw) we can revise this and enable both FMPs to be installed, as
long as they target different firmware hardware stores
Note that we are not using a Kconfig 'choice' on purpose, since we
