Hello Ingo, Thomas,
This is v2 of my pull request for the second batch of EFI updates for v5.7.
It incorporates the stable branch created to help get Hans's embedded
firmware stuff merged, so I am sending this as an ordinary pull request
as well.
Please pull.
The following changes since commit e9765680a31b22ca6703936c000ce5cc46192e10:

partitions/efi: Fix partition name parsing in GUID partition entry (2020-03-06 11:17:42 +0100)
----------------------------------------------------------------
More EFI updates for v5.7
- a fix for a boot regression in the IMA code on x86 booting without UEFI
- memory encryption fixes for x86, so that the TPM tables and the RNG
config table created by the stub are correctly identified as living in
unencrypted memory
- style tweak and doc update from Heinrich
- followup to the ARM EFI entry code simplifications to ensure that we
don't rely on EFI_LOADER_DATA memory being RWX
- fixes from Arvind to ensure that the new mixed mode approach works as
expected regardless of where the image is loaded in memory by the UEFI
PE/COFF loader
- more fixes from Arvind to make it more likely that the image can be
decompressed in place, regardless of where it was loaded in memory
- efivars bugfix and some cleanup from Vladis
- incorporate a stable branch with the EFI pieces of Hans's work on
loading device firmware from EFI boot service memory regions
- some followup fixes for the EFI stub changes that are queued for
v5.7 already
- an endianness fix for the EFI GPT partition table driver
