Jose Marinho 64a8aae15c efi: Add ESRT to the EFI system table 
The ESRT is initialised during efi_init_objlist after
efi_initialize_system_table().

The ESRT is recreated from scratch at the following events:
- successful UpdateCapsule;
- FMP instance install.

The code ensures that every ESRT entry has a unique fw_class value.

Limitations:
- The ESRT is not updated if an FMP instance is uninstalled;
- the fields image_type and flags are in the current implementation left
undefined. Setting these values will require a per-platform function
that returns the image_type/flags as a function of the image fw_class.

Select this option if you want to run UEFI applications (like GNU
GRUB or iPXE) on top of U-Boot. If this option is enabled, U-Boot
will expose the UEFI API to a loaded application, enabling it to
reuse U-Boot's device drivers.

bool "UEFI Boot Manager"

help
Select this option if you want to select the UEFI binary to be booted
via UEFI variables Boot####, BootOrder, and BootNext. This enables the
'bootefi bootmgr' command.

If OP-TEE is present and running StandAloneMM, dispatch all UEFI
variable related operations to that. The application will verify,
authenticate and store the variables on an RPMB.

Include a file with the initial values for non-volatile UEFI variables
into the U-Boot binary. If this configuration option is set, changes
to authentication related variables (PK, KEK, db, dbx) are not
allowed.

help
File with initial values of non-volatile UEFI variables. The file must
be in the same format as the storage in the EFI system partition. The
easiest way to create it is by setting the non-volatile variables in
U-Boot. If a relative file path is used, it is relative to the source
directory.

config EFI_VAR_BUF_SIZE
int "Memory size of the UEFI variable store"

help
This defines the size in bytes of the memory area reserved for keeping
UEFI variables.
When using StandAloneMM (CONFIG_EFI_MM_COMM_TEE=y) this value should
match the value of PcdFlashNvStorageVariableSize used to compile the
StandAloneMM module.
Minimum 4096, default 16384.

select EFI_SETUP_EARLY
help
Normally, without this option enabled, capsules will be
executed only at the first time of invoking one of efi command.
If this option is enabled, capsules will be enforced to be
executed as part of U-Boot initialisation so that they will
surely take place whatever is set to distro_bootcmd.

Some hardware does not support DMA to full 64bit addresses. For this
hardware we can create a bounce buffer so that payloads don't have to
worry about platform details.
config EFI_PLATFORM_LANG_CODES

help
This value is used to initialize the PlatformLangCodes variable. Its
value is a semicolon (;) separated list of language codes in native

GRUB prior to version 2.04 requires U-Boot to disable caches. This
workaround currently is also needed on systems with caches that
cannot be managed via CP15.

and one for the configuration table that is required from the spec
config EFI_LOAD_FILE2_INITRD

help
Linux v5.7 and later can make use of this option. If the boot option
selected by the UEFI boot manager specifies an existing file to be used
as initial RAM disk, a Linux specific Load File2 protocol will be
installed and Linux 5.7+ will ignore any initrd=<ramdisk> command line
argument.

Select this option to enable EFI secure boot support.
Once SecureBoot mode is enforced, any EFI binary can run only if
