a930d69baa efi_loader: replace a u16_strdup with alloc + memcpy
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

Update the sandbox implementation to use UCLASS_HOST and adjust all

- Update the 'host' command to use the new API
- Replace various uses of UCLASS_ROOT with UCLASS_HOST
- Disable test_eficonfig since it doesn't work (this should have a unit

- Update the blk test to use the new API
- Drop the old header file

53def68df5 efi_loader: AllocateAddress requires page address
AllocatePages() can be called with Type=AllocateAddress. Such a call can
only succeed if *Memory points to the address of an unallocated page range.

A call with *Memory being an address that is not page aligned must not

2b55ad304d efi_loader: discover if no efi_system_partition is set
Variable efi_system_partition holds the efi_system_partition. Currently it
is initialized as:

    {
      .uclass_id = 0 = UCLASS_ROOT,
      .denum = 0,
      .part = 0,
    }

This indicates that host 0:0 is the efi_system_partition and we see output
like:

    => bootefi hello
    ** Bad device specification host 0 **
    Couldn't find partition host 0:0

To identify that no EFI system partition has been set use UCLASS_INVALID.

8679405241 FWU: Add support for the FWU Multi Bank Update feature
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.

7e9814cc6c FWU: Add boot time checks as highlighted by the FWU specification
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.

fb63362c63 lib: fix buggy strcmp and strncmp
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.

c726fc01cf dm: treewide: Use uclass_first_device_err when accessing one device
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.

05c4c9e21a efi_loader: define internal implementations of install/uninstallmultiple
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

0dfc4c84d8 efi_selftest: prefix test functions with efi_st_

Rename static functions in the LoadImage() unit test adding an efi_st_
prefix.
