Has this been resolved now? Jammy is booting fine, right?

Title:
linux-image-5.11.0-1008-generic: cannot read initrd via
EFI_LOAD_FILE2_PROTOCOL
Status in linux-riscv package in Ubuntu:
Incomplete
Bug description:
I am running on QEMU riscv64 with upstream OpenSBI and U-Boot.
$ lsb_release -rd
Description: Ubuntu 21.04
Release: 21.04
In U-Boot I define a boot option and boot via UEFI:
efidebug boot add -b 0001 Ubuntu virtio 0:1 boot/vmlinuz-5.11.0-1008-generic
-i virtio 0:1 boot/initrd.img-5.11.0-1008-generic -s
'root=UUID=386038e2-e47c-49db-a74b-db2e730fa494 earlycon console=ttyS0'
efidebug boot order 0001
bootefi bootmgr
Loading the initial RAM disk fails due to a bug in the EFI kernel
stub:
U-Boot's implementation of the EFI_LOAD_FILE2_PROTOCOL is called with
buffer=NULL, *buffer_size=0 and returns the buffer size and status
code EFI_BUFFER_TOO_SMALL. Now the upstream kernel code would allocate
the memory and call the protocol a second time. But the Ubuntu kernel
does not allocate memory.
I added '#define DEBUG 1' to U-Boot's efi_memory.c to
efi_load_initrd.c to get more output:
