aaddce0d35 arm: a37xx: pci: Do not allow setting bars on PCI Bridge
PCI Bridge which represents Aardvark PCIe Root Port does not have
configurable bars.

So ensure that write operation to bars registers on PCI Bridge is noop and
bars registers always contain zero address which indicates that bars are
unsupported.

After this change U-Boot 'pci bar 0.0.0' command does not show any
allocated bars for PCI Bridge device.

a46877eeb2 tools: termios_linux.h: Fix tcsendbreak() implementation
There are two Linux ioctls which implements tcsendbreak() functionality:
TCSBRK and TCSBRKP

TCSBRK with non-zero parameter implements tcdrain() and with zero parameter
implements tcsendbreak() for duration of 0.25s.

TCSBRKP with zero parameter is same as TCSBRK and with non-zero parameter
implements tcsendbreak() for duration in deciseconds specified by
parameter. TCSBRKP does not have to be provided by older toolchain
versions.

So tcsendbreak() has to either use TCSBRK with zero parameter or TCSBRKP
with any parameter.

Fix code to use TCSBRKP and fallback to TCSBRK with 0.

567dfef2fe x86: Show some EFI info with the bdinfo command
It is useful to see some basic EFI info with the command as it forms part
of the information about a board.

Add a hook for this and show the table address as a start.

While here, fix an invalid cast in setup_efi_info(). Note that this
function is using a data structure defined by Linux so we cannot change
it. Also note that ulong is used since this is the standard in U-Boot
(>6k uses), despite there being quite a bit of the more verbose uintptr_t
(930 uses).

028abfd9b1 imx8mm-evk: Generate a single bootable flash.bin again
After the conversion to binman in commit 8996e6b7c6 ("imx8mm_evk: switch
to use binman to pack images"), it is necessary to flash both flash.bin and
u-boot.itb to get a bootable system. Prior to this commit, only flash.bin
was needed.

Such new requirement breaks existing distro mechanisms to generate the
final binary because the extra u-boot.itb is now required.

Generate a final flash.bin that can be used again as a single
bootable binary to keep the original behavior.

After this change the SPL binary is called spl.bin, which is a more
descriptive name for its purpose, and can still be used standalone
(for example, for secure boot purposes).

Also update imx8mm_evk.rst to remove the u-boot.itb copy step.

936bf17263 colibri-imx6ull: fix setup of nand gpmi clock
NXP used to setup the gpmi clock root from gpmi_clk in early versions
in their downstream BSP. [1]
However on mainline the gpmi clock root was always setup from enfc
since the beginning of the i.MX 6 series SoCs, which is still the same
today. [2]

NXP followed the mainline approach at some point and changed
setup_gpmi_io_clk to setup gpmi clock root from enfc which left faulty
code behind in our board file. [3]

This commit follows the change of NXP as it improves the performance of
the NAND from ~1.2 MiB/s to ~12 MiB/s. [3]

This change was verified to work in recovery-mode and u-boot loaded
from NAND on all four Colibri iMX6ULL SKUs from Toradex.

The frequency used to read the NAND, measured on RE# (Read Enable):
before this patch: 1.4 MHz
after this patch:   22 MHz
in Linux Kernel:    50 MHz
