This functions is used as a converter from IPv6 address string notation
to struct ip6_addr that is used everywhere in IPv6 implementation. For
example it is used to parse and convert IPv6 address from tftpboot
command. Conversion algorithm uses two passes, first to verify syntax and
locate colons and second pass to read the address. In case of valid IPv6
address it returns 0.
Examples of valid strings:
2001:db8::0:1234:1
2001:0db8:0000:0000:0000:0000:1234:0001
::1
::ffff:192.168.1.1
Examples of invalid strings
2001:db8::0::0 (:: can only appear once)
2001:db8:192.168.1.1::1 (v4 part can only appear at the end)
192.168.1.1 (we don't implicity map v4)

Some commands need to enumerate the existing UEFI load

Heinrich reports that on RISC-V unaligned access is emulated by OpenSBI
which is very slow. Performance wise it's better if we skip the calls
to u16_strdup() -- which in turn calls u16_strsize() and just allocate/copy the
memory directly. The access to dp.length may still be unaligned, but that's
way less than what u16_strsize() would do

The FWU Multi Bank Update feature supports updating firmware images
to one of multiple sets(also called banks) of images. The firmware
images are clubbed together in banks, with the system booting images
from the active bank. Information on the images such as which bank
they belong to is stored as part of the metadata structure, which is
stored on the same storage media as the firmware images on a dedicated
partition.
At the time of update, the metadata is read to identify the bank to
which the images need to be flashed(update bank). On a successful
update, the metadata is modified to set the updated bank as active
bank to subsequently boot from.

The FWU Multi Bank Update specification requires the Update Agent to
carry out certain checks at the time of platform boot. The Update
Agent is the component which is responsible for updating the firmware
components and maintaining and keeping the metadata in sync.
The spec requires that the Update Agent perform the following checks
at the time of boot
* Sanity check of both the metadata copies maintained by the platform.
* Get the boot index passed to U-Boot by the prior stage bootloader
and use this value for metadata bookkeeping.
* Check if the system is booting in Trial State. If the system boots
in the Trial State for more than a specified number of boot counts,
change the Active Bank to be booting the platform from.
Call these checks through the main loop event at the time of platform
boot.

There are two problems with both strcmp and strncmp:
(1) The C standard is clear that the contents should be compared as
"unsigned char":
The sign of a nonzero value returned by the comparison functions
memcmp, strcmp, and strncmp is determined by the sign of the
difference between the values of the first pair of characters (both
interpreted as unsigned char) that differ in the objects being
compared.
(2) The difference between two char (or unsigned char) values can
range from -255 to +255; so that's (due to integer promotion) the
range of values we could get in the *cs-*ct expressions, but when that
is then shoe-horned into an 8-bit quantity the sign may of course
change.
The impact is somewhat limited by the way these functions
are used in practice:
- Most of the time, one is only interested in equality (or for
strncmp, "starts with"), and the existing functions do correctly
return 0 if and only if the strings are equal [for strncmp, up to
the given bound].
- Also most of the time, the strings being compared only consist of
ASCII characters, i.e. have values in the range [0, 127], and in
that case it doesn't matter if they are interpreted as signed or
unsigned char, and the possible difference range is bounded to
[-127, 127] which does fit the signed char.
For size, one could implement strcmp() in terms of strncmp() - just
make it "return strncmp(a, b, (size_t)-1);". However, performance of
strcmp() does matter somewhat, since it is used all over when parsing
and matching DT nodes and properties, so let's find some other place
to save those ~30 bytes.

There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.
Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.
Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.
Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.

A following patch is cleaning up the core EFI code trying to remove
sequences of efi_create_handle, efi_add_protocol.
Although this works fine there's a problem with the latter since it is
usually combined with efi_delete_handle() which blindly removes all
protocols on a handle and deletes the handle. We should try to adhere to
the EFI spec which only deletes a handle if the last instance of a protocol
has been removed. Another problem is that efi_delete_handle() never checks
for opened protocols, but the EFI spec defines that the caller is
responsible for ensuring that there are no references to a protocol
interface that is going to be removed.
So let's fix this by replacing all callsites of
efi_create_handle(), efi_add_protocol() , efi_delete_handle() with
Install/UninstallMultipleProtocol.
In order to do that redefine functions that can be used by the U-Boot
proper internally and add '_ext' variants that will be used from the
EFI API
