  3. sd-image-raspberrypi4: Use u-boot for booting 

    This includes setting up everything for the mainline Raspberry Pi 4
image.

In fact, the only difference left in the Raspberry Pi 4-specific image
is the kernel from the vendor.

  4. linux: configure aarch64 contiguous memory allocator via kernel config 

    As per the in-line comment, this is where distros should configure it.
Not via kernel command line parameters.

As found by looking at the implementation, while exploring the cause of
a bug on the Raspberry Pi 4, it was found that `cma=` on the command
line parameters will overwrite the values a device tree will have
configured for a given platform.

With this, the more recent 5.4 vendor kernel boots just fine on the
Raspberry Pi 4 using our common configuration.
