[edk2-devel] [PATCH V5 0/6] SPI NOR Flash Driver for SFDP flash device

["Chang, Abner via groups.io" <abner.chang=amd.com@groups.io>]

From: Abner Chang <abner.chang@amd.com>

Sending V4 for review as SPI related ECR is approved by
PIWG in PI spec 1.8A

In V5: Correct patch 6/6, as some source files are fixed in this patch.
In RESEND V4: Add Cc in patch 6/6
In V4: Enhance timeout algorithm
In V3: Relocate GUIDs/PCDs for SPI SFDP drivers to
       MdeModulePkg.dec.
In V2: Add maintainer entry for Bus/Spi.

This patch fixes the missing SPI defintions per to PI spec
1.8 errata A.
This patch also provides the implemtation of SPI NOR flash
driver that supports JEDEC SFDP specification.
This driver support the flash device that has the GUID
gEdk2JedecSfdpSpiDxeDriverGuid or gEdk2JedecSfdpSpiSmmDriverGuid
declared in EFI_SPI_PERIPHERAL SpiPeripheralDriverGuid structure.

The driver has been verified with Macronix MX25U6435F flash device.
