Is your feature request related to a problem? Please describe.
Das U-Boot and derivative projects (such as Tow-Boot) support loading UEFI payloads, but have some limitations. When it comes to iPXE, U-Boot has some details in their documentation on building iPXE for it, which just involves adding a few lines to src/config/local/nap.h to disable cpu sleep support. This would allow for hardware which doesn't come with a full-fledged bootloader to make use of netboot.xyz without the need of custom-made builds.

Describe the solution you'd like
Consider the possibility of adding a new build which includes this patch or applying this patch globally to the aarch64 builds.
For a list of devices which could benefit from it, you can check the list of supported devices of Tow-Boot.

Describe alternatives you've considered

There are some SBCs that can be used with EDK2, but it is a much broader project which not every platform can support.
