Subject: [PATCH] OvmfPkg: allow exclusion of the shell from the firmware image
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.
