Subject: [PATCH v2 0/2] efi/arm: deal with HYP mode boot
Date: Sun,  7 Jun 2020 15:58:32 +0200	[thread overview]
Message-ID: <20200607135834.898294-1-ardb@kernel.org> (raw)

Some changes to make booting in HYP mode via EFI more robust.

Changes since v2:
- Use the correct register for testing/disabling the HYP MMU
- Don't pretend we're in SVC mode for the HYP+caches case, but set up a HYP
  exception handler for HVC instructions issued from HYP mode*** BLURB HERE ***

Ard Biesheuvel (2):
  efi/arm: decompressor: deal with HYP mode boot gracefully
  efi/arm: libstub: print boot mode and MMU state at boot
