Subject: [PATCH 5/6] OvmfPkg/VirtNorFlashDxe: ValidateFvHeader: unwritten
state is EOL too

RH-Commit: [5/6] 24a9f2d03eeaf61ea8f0ea5a40f0921994b08688 (kraxel.rh/centos-src-edk2)
It is possible to find variable entries with State being 0xff, i.e. not
updated since flash block erase. This indicates the variable driver
could not complete the header write while appending a new entry, and
therefore State was not set to VAR_HEADER_VALID_ONLY.
This can only happen at the end of the variable list, so treat this as
additional "end of variable list" condition.

NorFlashWriteBuffer calls.
RH-Author: Gerd Hoffmann <None>

RH-Commit: [3/6] 993426855451252f1126348e107e386b07314bfd (kraxel.rh/centos-src-edk2)
Replace the two NorFlashWriteBuffer() calls with a loop containing a
single NorFlashWriteBuffer() call.
With the changes in place the code is able to handle updates larger
than two P30_MAX_BUFFER_SIZE_IN_BYTES blocks, even though the patch
does not actually change the size limit.

Raise the limit for writes without block erase from two to four
P30_MAX_BUFFER_SIZE_IN_BYTES blocks. With this in place almost all efi
variable updates are handled without block erase. With the old limit
some variable updates (with device paths) took the block erase code
path.

RH-Commit: [2/6] e2f2231fd1b7b702aa5372e790c1d2c06ca79f74 (kraxel.rh/centos-src-edk2)
Introduce 'Start' and 'End' variables to make it easier to follow the
logic and code flow. Also add a ascii art diagram (based on a
suggestion by Laszlo).
This also fixes the 'Size' calculation for the NorFlashRead() call.
Without this patch the code will read only one instead of two
P30_MAX_BUFFER_SIZE_IN_BYTES blocks in case '*NumBytes' is smaller than
P30_MAX_BUFFER_SIZE_IN_BYTES but 'Offset + *NumBytes' is not, i.e. the
update range crosses a P30_MAX_BUFFER_SIZE_IN_BYTES boundary.
