Package: linux-image-arm64
Version: 4.19+105+deb10u4
Severity: important
Tags: d-i

Dear Maintainer,

I am testing with ARM64 systems with u-boot. Debian is booted in EFI mode and properly detects the EFI system tables. 

[    0.000000] efi: EFI v2.80 by Das U-Boot                                                                                                 
[    0.000000] efi:  RTPROP=0x3aef9040  SMBIOS=0x3aeee000  RNG=0x39b81040  MEMRESERVE=0x39b80040                                            
[    0.000000] efi: seeding entropy pool  


Anytime I kexec the same or another Debian kernel, I get the following message:

[    0.000000] efi: Getting EFI parameters from FDT:
[    0.000000] efi: Can't find 'System Table' in device tree!

This problem is occuring with both 4.19, 5.4, 5.6, and 5.7 from Debian. It does not occur with SUSE or Fedora kernels.
