Subject: [PATCH 18/18] OvmfPkg: clone NorFlashPlatformLib into
|
|
VirtNorFlashPlatformLib
|
|
|
|
RH-Author: Gerd Hoffmann <None>
|
|
RH-MergeRequest: 43: OvmfPkg/VirtNorFlashDxe backport
|
|
RH-Jira: RHEL-17587

RH-Commit: [20/20] 50ea104b99a997d7d08c1fdef617df1d930ffae6
|
|
|
|
Create a new library class in Ovmf that duplicates the existing
|
|
NorFlashPlatformLib, but which will be tied to the VirtNorFlashDxe
|
|
driver that will be introduced in a subsequent patch. This allows us to
|
|
retire the original from ArmPlatformPkg.
