Subject: [PATCH 08/21] OvmfPkg: allow exclusion of the shell from the firmware
image (RH only)
Notes about the RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] ->
RHEL-8.5/20210520-e1999b264f1f [edk2-stable202105] rebase:
- No manual / explicit code change is necessary, because the newly
inherited OvmfPkg/AmdSev platform already has its own BUILD_SHELL
build-time macro (feature test flag), with default value FALSE -- from
upstream commit b261a30c900a ("OvmfPkg/AmdSev: add Grub Firmware Volume
Package", 2020-12-14).
- Contextual differences from new upstream commits 2d8ca4f90eae ("OvmfPkg:
enable HttpDynamicCommand", 2020-10-01) and 5ab6a0e1c8e9 ("OvmfPkg:
introduce VirtioFsDxe", 2020-12-21) have been auto-resolved by
git-cherry-pick.
- Remove obsolete commit message tags related to downstream patch
management: Message-id, Patchwork-id, O-Subject, Acked-by
(RHBZ#1846481).

- context difference from upstream commit ec41733cfd10 ("OvmfPkg: add the
'initrd' dynamic shell command", 2020-03-04) correctly auto-resolved

- 4b888334d234 ("OvmfPkg: Remove EdkShellBinPkg in FDF", 2018-11-19)

tool chain", 2018-11-27)

- reorder the rebase changelog in the commit message so that it reads like
a blog: place more recent entries near the top
- no changes to the patch body

Bugzilla: 1147592
When '-D EXCLUDE_SHELL_FROM_FD' is passed to 'build', exclude the shell
binary from the firmware image.
Peter Jones advised us that firmware vendors for physical systems disable
the memory-mapped, firmware image-contained UEFI shell in
SecureBoot-enabled builds. The reason being that the memory-mapped shell
can always load, it may have direct access to various hardware in the
system, and it can run UEFI shell scripts (which cannot be signed at all).
Intended use of the new build option:
- In-tree builds: don't pass '-D EXCLUDE_SHELL_FROM_FD'. The resultant
firmware image will contain a shell binary, independently of SecureBoot
enablement, which is flexible for interactive development. (Ie. no
change for in-tree builds.)
- RPM builds: pass both '-D SECURE_BOOT_ENABLE' and
'-D EXCLUDE_SHELL_FROM_FD'. The resultant RPM will provide:
- OVMF_CODE.fd: SecureBoot-enabled firmware, without builtin UEFI shell,
- OVMF_VARS.fd: variable store template matching OVMF_CODE.fd,
- UefiShell.iso: a bootable ISO image with the shell on it as default
boot loader. The shell binary will load when SecureBoot is turned off,
and won't load when SecureBoot is turned on (because it is not
signed).
UefiShell.iso is the reason we're not excluding the shell from the DSC
files as well, only the FDF files -- when '-D EXCLUDE_SHELL_FROM_FD'
is specified, the shell binary needs to be built the same, only it
will be included in UefiShell.iso.
