Michael Karcher found out that the second issue is that the kernel is too big and
overwrites the decompression code while being uncompressed.
Raising the the value for CONFIG_BOOT_LINK_OFFSET fixes the problem and lets the
kernel boot but we still have the problem that qemu probably needs to be adjusted
in order to accommodate for the larger kernel, see [1].
Any suggestions how to resolve this problem?
