Patrick Rudolph 6d722894fd board: emulation: Add QEMU sbsa support
Add support for Arm sbsa [1] v0.3+ that is supported by QEMU [2].

Unlike other Arm based platforms the machine only provides a minimal
FDT that contains number of CPUs, ammount of memory and machine-version.
The boot firmware has to provide ACPI tables to the OS.
Due to this design a full DTB is added here as well that allows U-Boot's
driver to properly function. The DTB is appended at the end of the U-Boot
image and will be merged with the QEMU provided DTB.

In addition provide documentation how to use, enable binman to fabricate both
ROMs that are required to boot and add ACPI tables to make it full compatible
to the EDK2 reference implementation.

The board was tested using Fedora 40 Aarch64 Workstation. It's able
to boot from USB and AHCI or network.

Tested and found working:
- serial
- PCI
- xHCI
- Bochs display
- AHCI
- network using e1000e
- CPU init
- Booting Fedora 40

This patch series adds support for ZFS listing and load to u-boot.

To Enable zfs ls and load commands, modify the board specific config file with
#define CONFIG_CMD_ZFS

Steps to test:

1. After applying the patch, zfs specific commands can be seen
   in the boot loader prompt using
	UBOOT #help

	zfsload- load binary file from a ZFS file system
	zfsls  - list files in a directory (default /)

2. To list the files in zfs pool, device or partition, execute
	zfsls <interface> <dev[:part]> [POOL/@/dir/file]
	For example:
	UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/

3. To read and load a file from an ZFS formatted partition to RAM, execute
	zfsload <interface> <dev[:part]> [addr] [filename] [bytes]
	For example:
	UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage
