According to Android image format [1], kernel image resides at 1 page
offset from the boot image address. Grab the magic number from there
and allow U-Boot to handle LZ4-compressed KNL binaries instead of
hardcoding compression type to IH_COMP_NONE. Other compression types,
if needed, can be added later.
Tested on H3ULCB-KF using the image detailed in [2].

The UEFI variables PlatformLang and PlatformLangCodes specify the current
firmware language and the list of all available languages.
Currently their values are hard coded. With the patch a new configuration
variable EFI_PLATFORM_LANG_CODES is provided.
When initializing the UEFI subsystem this configuration variable is used to
initialize PlatformLangCodes. The value of variable PlatformLang is read.
If it is not set, the first language specified in EFI_PLATFORM_LANG_CODES
is used to initialize PlatformLang.

The first functions of the UEFI sub-system are invoked before reaching the
U-Boot shell, e.g. efi_set_bootdev(), efi_dp_from_name(),
efi_dp_from_file(). We should be able to print out device paths for
debugging purposes here.
When printing device paths via printf("%pD\n", dp) this invokes functions
defined as EFIAPI. So efi_save_gd() must be called beforehand.
So let's move the efi_save_gd() call to function initr_reloc_global_data(()
in board_r.c.

The new fdt_generate_phandle() function can be used to generate a new,
unused phandle given a specific device tree blob. The implementation is
somewhat naive in that it simply walks the entire device tree to find
the highest phandle value and then returns a phandle value one higher
than that. A more clever implementation might try to find holes in the
current set of phandle values and fill them. But this implementation is
relatively simple and works reliably.
Also add a test that validates that phandles generated by this new API
are indeed unique.

When phys_addr_t printf specifier support was first introduced in commit
1eebd14b79 ("vsprintf: Add modifier for phys_addr_t"), it was enabled
only if CONFIG_CMD_NET was selected. Since physical addresses are not
unique to networking support it doesn't make sense to conditionally add
it in those cases only. Move support for it outside of the CMD_NET guard
so that the specifier is always supported.

Currently, image's image_base points to an address where the image was
temporarily uploaded for further loading. Since efi_loader relocates
the image to final destination, image_base and image_size should reflect
that.
This bug was detected in UEFI SCT, "Loaded Image Protocol Test - test 2,"
which shows that 'Unload' function doesn't fit into a range suggested by
image_base and image_size.
