Similar to a "real" UEFI implementation, the bootmgr looks at the
BootOrder and BootXXXX variables to try to find an EFI payload to load
and boot. This is added as a sub-command of bootefi.
The idea is that the distro bootcmd would first try loading a payload
via the bootmgr, and then if that fails (ie. first boot or corrupted
EFI variables) it would fallback to loading bootaa64.efi. (Which
would then load fallback.efi which would look for \EFI\*\boot.csv and
populate BootOrder and BootXXXX based on what it found.)

Add EFI variable support, mapping to u-boot environment variables.
Variables are pretty important for setting up boot order, among other
things. If the board supports saveenv, then it will be called in
ExitBootServices() to persist variables set by the efi payload. (For
example, fallback.efi configuring BootOrder and BootXXXX load-option
variables.)
Variables are *not* currently exposed at runtime, post ExitBootServices.
On boards without a dedicated device for storage, which the loaded OS
is not trying to also use, this is rather tricky. One idea, at least
for boards that can persist RAM across reboot, is to keep a "journal"
of modified variables in RAM, and then turn halt into a reboot into
u-boot, plus store variables, plus halt. Whatever the solution, it
likely involves some per-board support.
Mapping between EFI variables and u-boot variables:
efi_$guid_$varname = {attributes}(type)value
For example:
efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_OsIndicationsSupported=
"{ro,boot,run}(blob)0000000000000000"
efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_BootOrder=
"(blob)00010000"
The attributes are a comma separated list of these possible
attributes:
+ ro - read-only
+ boot - boot-services access
+ run - runtime access
NOTE: with current implementation, no variables are available after
ExitBootServices, and all are persisted (if possible).
If not specified, the attributes default to "{boot}".
The required type is one of:
+ utf8 - raw utf8 string
+ blob - arbitrary length hex string

This is not true in many cases. Enhance the implementation to scan all
phandles in a property and to use the correct number of arguments (which
can be 0, 1, 2 or more) when generating the C code. For the struct
definitions, use a struct which can hold the maximum number of arguments
used by the property.

When using 32-bit addresses dtoc works correctly. For 64-bit addresses it
does not since it ignores the #address-cells and #size-cells properties.
Update the tool to use fdt64_t as the element type for reg properties when
either the address or size is larger than one cell. Use the correct value
so that C code can obtain the information from the device tree easily.
Alos create a new type, fdt_val_t, which is defined to either fdt32_t or
fdt64_t depending on the word size of the machine. This type corresponds
to fdt_addr_t and fdt_size_t. Unfortunately we cannot just use those types
since they are defined to phys_addr_t and phys_size_t which use
'unsigned long' in the 32-bit case, rather than 'unsigned int'.
Add tests for the four combinations of address and size values (32/32,
64/64, 32/64, 64/32). Also update existing uses for rk3399 and rk3368
which now need to use the new fdt_val_t type.
