Subject: [PATCH 04/18] OvmfPkg/VirtNorFlashDxe: drop block I/O protocol
implementation
RH-Author: Gerd Hoffmann <None>
RH-MergeRequest: 43: OvmfPkg/VirtNorFlashDxe backport
RH-Jira: RHEL-17587
RH-Acked-by: Laszlo Ersek <lersek@redhat.com>
RH-Commit: [6/20] 6843078997a30c2818e0d53a90fb7f6accb89aaf
We never boot from NOR flash, and generally rely on the firmware volume
PI protocols to expose the contents. So drop the block I/O protocol
implementation from VirtNorFlashDxe.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
Reviewed-by: Sunil V L <sunilvl@ventanamicro.com>
(cherry picked from commit 83f11f957240ead9b135a778316330762b0a3acb)
