Add support for the following ZII i.MX8MQ based boards:
- ZII i.MX8MQ RMB3
- ZII i.MX8MQ Zest
Most of the basic peripherals are supported by this patch. More
advanced features such as PCIe, display support, etc, are planned to
be added later.

We don't intend to ship any files in this directory, so there is no
risk of the directory getting too crowded over time. Drop the subdir
as this makes it easier for a outer build system to drop all the
needed firmwares into the correct directory.

Add support for the Xilinx Zynq Ultrascale+ MPSoC architecture (ZynqMP)
and the Xilinx ZCU104 board.
Barebox is booted as BL33 in EL-1 and expects that a BL2 (i.e. the FSBL)
already took care of initializing the RAM. Also for debug_ll, the UART
is expected to be already setup correctly. Thus, you have to add the
Barebox binary to a boot image as described in "Chapter 11: Boot and
Configuration" of "Zynq Ultrascale+ Device Technical Reference Manual".

arm64 has no __naked__ attribute and the compiler adds a function prologue
for saving x29 and x30 to the stack for all C functions. This includes
functions defined using the ENTRY_FUNCTION macro. Therefore, the stack
needs to be setup before entering a C function, which is not possible if
the entry is a C function.
Provide a macro to implement the entry in assembly to be able to setup the
stack before entering the low level entry function.

Without this flag, gcc generates code to save the Q/V registers to the
stack for handling the va_list in pr_print(). Saving the registers is
useless, as the registers are never restored, but accessing the
registers to save them hangs the CPU.
Follow the Linux arch/arm64/Makefile and use the general-regs-only flag
to prevent usage of floating point and Advanced SIMD register.

Commit e1287b1a8b27 ("arm: rework lib directory to support arm64")
restructured the lib directory and added the lib64 directory. It moved
the existing .gitignore to the lib32 directory but didn't add a new
.gitignore for lib64.
Thus building Barebox for arm64 results in stray barebox.lds files.
Copy the .gitignore from lib32 to lib64.

nmon is a tiny (<1024 bytes) monitor program
for the RV32I processors.
It can operate with NO working RAM at all!
It uses only the processor registers and NS16550-compatible
UART port for operation, so it can be used for a memory
controller setup code debugging.

at91_add_device_mci() was missing configuration of PIOA6
when configuring mci1.
With this fix we can read data from SD card with at91sam9263ek,
when built without DT.
Building without a DT is required when we do a bootstrap build.
The other at91samxxx_devices was checked - only the 9263 was
missing the CLK configuration for mci1.
