Bump U-Boot and Linux kernel versions. Updating U-Boot to 2021.04 requires the following two changes. First, after switching to binman, u-boot.itb is no more generated for 64-bit sunxi boards. Combined u-boot-sunxi-with-spl.bin image should be used instead. This image contains SPL, U-Boot, and FIT image, where FIT image contains other binaries such as BL31 and SCP. Second, new U-Boot enables support for System Control Processor (SCP) firmware. SCP firmware is included by default into FIT image in the combined u-boot-sunxi-with-spl.bin binary. When SCP is not available or not needed, it should be explicitly disabled by pointing to an empty file. Support for Allwinner SCP firmware is not yet available neither in Buildroot nor in mainline kernel. So disable it for now using custom U-Boot build options.

Intro
=====
This default configuration will allow you to start experimenting with the
buildroot environment for the Orangepi Zero Plus2. With the current configuration
it will bring-up the board, and allow access through the serial console.

Wiki link:

This configuration uses U-Boot mainline and kernel mainline.
How to build
============
$ make orangepi_zero_plus2_defconfig
$ make
Note: you will need access to the internet to download the required
sources.
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.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
$ sudo sync
Insert the micro SDcard in your Orangepi Zero Plus2 and power it up. The console
is on the serial line, 115200 8N1.
