I managed to boot U-Boot, chain load iPXE (probably not necessary since U-Boot is capable enough) but when pulling the regular aarch64 vmlinuz/initrd.gz pxeboot images it just errors out with an error saying "Invalid application". My knowledge about the kernel/initramfs chain gets blurry here which is why all tries in altering the initrd.gz image have failed gloriously.
I don't know much about this, but "Invalid application" suggests that iPXE doesn't like the kernel image you're trying to start. Unless it's uboot not liking your iPXE.
