For legacy usb storage driver, USB_MAX_STOR_DEV is defined as 7.
If we only have one usb disk on board, `usb dev 0` is ok.
But if `usb dev 1`, still ok, then `usb read xxx` will trigger
system fault and reboot.
So check if_type before using this device.

We introduced special "DEBUG_EFI" defines when the efi loader
support was new. After giving it a bit of thought, turns out
we really didn't have to - the normal #define DEBUG infrastructure
works well enough for efi loader as well.
So this patch switches to the common debug() and #define DEBUG
way of printing debug information.

Some times you may want to exit an EFI payload again, for example
to default boot into a PXE installation and decide that you would
rather want to boot from the local disk instead.
This patch adds exit functionality to the EFI implementation, allowing
EFI payloads to exit.

These functions are part of the Linux 4.6 sync. They are being added

nand_info[] is now an array of pointers, with the actual mtd_info
instance embedded in struct nand_chip.
This is in preparation for syncing the NAND code with Linux 4.6,
which makes the same change to struct nand_chip. It's in a separate
commit due to the large amount of changes required to accommodate the
change to nand_info[].

We can now successfully boot EFI applications from disk, but users

If serial support is not compiled into U-Boot, which may be the case
for some SPL builds, the following warning will be generated in disk.c:
cmd/disk.c: In function 'common_diskboot':
cmd/disk.c:16:6: warning: variable 'dev' set but not used [-Wunused-but-set-variable]
int dev, part;
^
The warning is a result of printf() calls being optimized away, and
thus the whole dev variable becomes indeed unused. Mark the variable
as __maybe_unused .

The arm64 Linux boot protocol [1] describes the fields in the Image
header as being 64-bit little endian values.
So fix the endianess conversion to use 64-bit sized operations, for
both image_size and text_offset.
Also we use a local variable for the image_size to avoid both writing
to the header and also accessing it after we actually unmapped it.

Introduce the (optional) eeprom print and eeprom update commands.
These commands are eeprom layout aware:
* The eeprom print command prints the contents of the eeprom in a human
readable way (eeprom layout fields, and data formatted to be fit for human
consumption).
* The eeprom update command allows user to update eeprom fields by specifying
the field name, and providing the new data in a human readable format (same
format as displayed by the eeprom print command).
* Both commands can either auto detect the layout, or be told which layout to
use.
New CONFIG options:
CONFIG_CMD_EEPROM_LAYOUT - enables commands.
CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported
Feature API:
__weak int parse_layout_version(char *str)
- override to provide your own layout name parsing
__weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version);
- override to setup the layout metadata based on the version
__weak int eeprom_layout_detect(unsigned char *data)
- override to provide your own algorithm for detecting layout version
eeprom_field.c
- contains various printing and updating functions for common types of
eeprom fields. Can be used for defining custom layouts.

The bootefi cmd today fetches its device tree pointer from either the
location appointed by "fdt addr" with a fallback to the U-Boot control
fdt.

directly into the bootefi command instead and move the control fdt
