[PATCH 0/2] OvmfPkg, SecurityPkg: small followup patches after the TPM2 addition to OVMF

[Laszlo Ersek]

Repo:   https://github.com/lersek/edk2.git
Branch: ovmf_tcg2_followup

The first patch brings small coding style improvements to
OvmfPkg/Tcg/Tcg2Config. The second patch trims a superfluous PPI from
SecurityPkg/Tcg/TcgPei's DEPEX.

[PATCH 1/2] OvmfPkg/Tcg2ConfigPei: trivial coding style updates

[Laszlo Ersek]

- the @file comment block should match between INF and main C file

- rewrap / refill columns to 79 characters

- insert space before opening paren

- prefix and suffix //-style comment block with empty // lines

- fix indentation of arguments in multi-line function call

- general tab spacing (indent step) is 2 in edk2, unlike QEMU's 4

No functional changes.

[PATCH 2/2] SecurityPkg/TcgPei: drop PeiReadOnlyVariable from Depex

[Laszlo Ersek]

TcgPei doesn't actually use the PEI-phase read-only variable service, so
drop that from the Depex.

This patch was inspired by commit ab9e11da6651 ("SecurityPkg/Tcg2Pei: drop
PeiReadOnlyVariable from Depex", 2018-03-09).
