Adds support to the N1xxWU board series in the ClevoOpenBoardPkg
to write debug messages to a dedicated area on SPI flash. This
supports simple closed chassis debug. At this time, only a PEI
library instance is added since it is anticipated an alternative
mechanism will be available in DXE such as USB debug.

Adds a new library PeiSpiLib to perform the initialization necessary
to perform SPI write cycles in PEI. After initialization, it installs
an instance of the PCH_SPI_PPI.

Updates the total BIOS flash image size to 0x5E0000. This size
matches the BIOS region size already configured in the SPI
flash descriptor.

To write an image produced from the N1xxWU board build, write
the N1XXWU.fd file (~6 MB) to the beginning of the BIOS region
in the SPI flash (currently 0x220000).

Always back up the original SPI flash image. These offsets and
sizes are subject to change over time.

Adds a new SerialPortLib instance to the ClevoOpenBoardPkg to support
writing debug messages to a dedicated area on SPI flash. This is to
enable closed chassis debug support on the system.

DXE and later phases after memory initialization are expected to use
USB debug.

Subject: [edk2-platforms/devel-MinPlatform][PATCH v3 3/3] ClevoOpenBoardPkg/N1xxWU: Write PEI debug messages to SPI flash

Adds a new SerialPortLib instance to the ClevoOpenBoardPkg to support writing debug messages to a dedicated area on SPI flash. This is to enable closed chassis debug support on the system.

DXE and later phases after memory initialization are expected to use USB debug.

Subject: [edk2-platforms/devel-MinPlatform][PATCH v3 2/3] ClevoOpenBoardPkg/N1xxWU: Flash map update

Updates the total BIOS flash image size to 0x5E0000. This size matches the BIOS region size already configured in the SPI flash descriptor.

To write an image produced from the N1xxWU board build, write the N1XXWU.fd file (~6 MB) to the beginning of the BIOS region in the SPI flash (currently 0x220000).

Always back up the original SPI flash image. These offsets and sizes are subject to change over time.

Subject: [edk2-platforms/devel-MinPlatform][PATCH v3 1/3] KabylakeSiliconPkg: Add SPI write support in PEI

Adds a new library PeiSpiLib to perform the initialization necessary to perform SPI write cycles in PEI. After initialization, it installs an instance of the PCH_SPI_PPI.
