This introduces an alternative board build for the MacchiatoBin based on
EDK2 (UEFI) firmware loaded as BL33 by ARM Trusted Firmware.

Signed-off-by: Dick Olsson <hi at senzilla.io>

---

Revision 5:

 * Fixed incorrect Linux version statement in readme.txt
 * Replaced kernel EFI stub mode with GRUB2 for more convenience
 * The GRUB2 package handles the efi-part image
 * Simplified the post script
 * Removed the startup.nsh in favour of that provided by GRUB2
 * Re-exported the defconfig

Revision 4:

 * Renamed post-image.sh to assemble-flash-images
 * Updated to Linux LTS kernel 5.10
 * Added startup.nsh for auto-booting from the EFI shell

+Intro
+=====
+
+This is the board support for MacchiatoBin with a more modern firmware stack
+compared to the original build with board/solidrun/macchiatobin.
+
+The goal with this default configuration is to provide a build as close to
+ARM Server Base Boot Requirement (SBBR) as possible. This gives us the
+following benefits:
+
+ - The firmware is built and flashed separately from the OS image
+ - Therefore, the board will boot with any standard Aarch64 distribution image
+ - UEFI provides a more standardized firmware interface
+
+How to build
+============
+
+The default configuration provides the following stack:
+
+ - ARM Trusted Firmware (mainline)
+ - EDK2 UEFI firmware (mainline)
+ - Linux 5.10 (mainline)
+
+    $ make solidrun_macchiatobin_efi_defconfig
+    $ make
+
+The next step will depend on whether you have U-Boot or UEFI flashed on the
+board.
+
+How to flash the firmware from U-Boot
+=====================================
+
+In this example we will assume that the board has U-Boot flashed on it. We will
+flash the new UEFI firmware from the U-Boot console to the SPI flash, using
+the "bubt" (Burn ATF) command.
+
+Once the build process is finished you will have an image called
+"flash-image.bin" in the output/images/ directory.
+
+First, format a USB drive with an EXT4 partition and copy the "flash-image.bin"
+file onto the USB drive.
+
+Second, attach to the serial console[1], insert the USB drive into the board,
+boot the board and enter the U-Boot console. On the U-Boot console enter the
+following commands:
+
+    usb start
+    bubt flash-image.bin spi usb
+
+Lastly, unplug the USB drive and reboot the board. The board will now
+boot with the newly flashed UEFI firmware.
+
+How to flash the firmware from UEFI
+===================================
+
+In this example we will assume that the board has UEFI flashed on it. We will
+flash the new UEFI firmware from the old UEFI console to the SPI flash, using
+the "fupdate" command.
+
+First, format a USB drive with an FAT partition and copy the "flash-image.bin"
+file onto the USB drive.
+
+Second, attach to the serial console[1], insert the USB drive into the board,
+boot the board and enter the UEFI shell. In the UEFI shell, find what file
+system your USB drive got mapped to by using the "map" and "ls" commands.
+Then enter this command (assuming your USB drive is on "FS0"):
+
+    fupdate FS0:\flash-image.bin spi
+
+Lastly, unplug the USB drive and reboot the board. The board will now
+boot with the newly flashed UEFI firmware.
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory. This image only contains the Linux kernel and
+the rest of the operating system.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M conv=fsync
+  $ sudo sync
+
+Plug in the SD card into the board and boot.
+
+Note that because the board is now using UEFI firmware, the board will also
+boot any other standard Aarch64 distribution image.
