During USB boot U-Boot is supposed to download some firmware over USB.
It's done by EL3 software, so it has to be requested via corresponding
SMC call. Implement a routine for doing that.
No functional change.

The LDFW firmware loading is done in two steps:
1. Read the firmware binary from some block device
2. Provide it to EL3 monitor software via an SMC call, so it can copy
it to a Secure World memory and start using it
Let's split the load_ldfw() function by two functions correspondingly,
to reflect that process better:
- load_ldfw_from_blk()
- init_ldfw()
It can be useful in case when the LDFW binary should be obtained from
some different media, e.g. downloaded over USB during USB boot.

Implement functionality to check the current boot device (a device where
the SoC ROM code is loading the bootloaders from). The boot device order
can be changed using the SW1 DIP switch on the E850-96 board (which
controls XOM SoC lines), as stated in [1].
The boot device information is requested from EL3 software using the
corresponding SMC call, which in turn reads it from iRAM memory, which
was written by the ROM code. New routines decode that data and allow the
user to check the current boot device, boot order, etc. That API can be
used further to implement different code flows depending on the current
boot device, e.g.:
- on eMMC boot: obtain the firmware binaries from eMMC
- on USB boot: download the firmware over USB instead
No functional change; this patch only adds new functionality but it's
not used yet.

In TEZI (Toradex Easy Installer), we use one U-Boot binary for both our
NAND and eMMC Colibri iMX7 modules. Currently, CONFIG_PREBOOT sets the
environment variable 'fdtfile' depending on which defconfig was used,
adding the '-emmc' variant for the emmc defconfig. Since we always build
the TEZI recovery U-Boot with the standard (non-emmc) defconfig, fdtfile
has to be overwritten later or it will be wrong there.
By using '$variant', the fdtfile var is properly constructed at run time
for both the NAND and eMMC variants, and we do not have to worry about
setting fdtfile again when building the recovery TEZI U-Boot.
This also synchronizes these configs with how we handle the iMX6ULL.

There is a condition guard which ensures that the GPIO node, indeed
describes a GPIO controller.
if (!fdtdec_get_bool(blob, node, "gpio-controller"))
continue;
Since the bank base is being incremented in the loop, it is done so
irrespective of whether the node is a GPIO controller or not. This leads
to the incorrect resolution of bank base addresses.
Move it out of the loop, and instead increment the bank base address
only if the driver successfully binds a GPIO controller.

The fdt_addr variable is used in extlinux as a fallback devicetree if
none is provided by the boot command. Otherwise the only use in U-Boot
seems to me efi_install_fdt() when the internal FDT is required.
The existing mechanism uses the devicetree provided to U-Boot, but in
its original, unrelocated position. In my testing on an rpi_4, this ends
up at 2b35ef00 which is not a convenient place in memory, if the ramdisk
is large.
U-Boot already deals with this sort of problem by relocating the FDT
to a safe address.
So use the control-FDT address instead.
Remove the existing comment, which is confusing, since the FDT is not
actually passed unmodified to the kernel: U-Boot adds various things
using its FDT-fixup mechanism.
Note that board_get_usable_ram_top() reduces the RAM top for boards with
less RAM. This behaviour is left unchanged as there is no other
mechanism for U-Boot to handle this.

This patch adds support for configuring GPIO pull-up and pull-down
resistors in the BCM283x pinctrl driver. It implements the brcm,pull
device tree property to control pin bias settings.
The implementation follows the hardware-specific pull control
mechanisms:
- BCM2835: two-step GPPUD register sequence
- BCM2711: direct per-pin control registers
This enables device tree configurations to specify pull-up, pull-down,
or no bias for individual GPIO pins.
Tested on Raspberry Pi boards with both BCM2835 and BCM2711 SoCs.

Fix two memory allocation bugs in label_boot_extension():
1. When label->fdtdir is not set, overlay_dir was used without any
memory allocation.
2. When label->fdtdir is set, the allocation size was incorrect,
using 'len' (just the fdtdir length) instead of 'dir_len' (which
includes the trailing slash and null terminator).
Resolve both issues by moving the memory allocation and string
formatting outside the conditional block, resulting in clearer code
flow and correct sizing in all cases.

As stated in PXELINUX doc [1], the PXE configuration file has to be in
the format of "01-MAC-address" for Ethernet connections:
The hardware type (using its ARP "htype" code) and address, all in
lowercase hexadecimal with dash separators. For example, for an
Ethernet (i.e. ARP hardware type "1") with address
"88:99:AA:BB:CC:DD", it would search for the filename
"01-88-99-aa-bb-cc-dd".
Indeed, PXE implementation in U-Boot looks for files like that, as can
be seen from this call chain:
format_mac_pxe()
pxe_mac_path()
pxe_get()
extlinux_pxe_read_bootflow()
Mention the fact that PXE expects the configuration file to be prepended
with "01" in the PXE section of E850-96 documentation. While at it, fix
some other minor issues in PXE section.
