Subject: EmbeddedPkg/PrePiLib: Remove the performance measurements from the library
X-Git-Tag: edk2-stable201903~14566
X-Git-Url: https://git.proxmox.com/?p=mirror_edk2.git;a=commitdiff_plain;h=6da6db17a48485e947d8e4e4c1688b29c23fc3d2

EmbeddedPkg/PrePiLib: Remove the performance measurements from the library

The PrePiLib should really be used for the PEI phase (not the SEC phase).
It is the DXE core that take the tick for the end of the PEI phase.

The Platform PrePi module should be responsible to take the tick when it
starts for the PEI phase.
