Richard Hughes eddaed0c11 Allow specifying more than one VendorID for a device 
Asking the user for the UID mapping isn't working very well, as it requires lots
of manual handholding. It also doesn't work very well when the device vendor
does not actually have a PCI ID or if the vendor has split into two entities.

Just use the OUI address as an additional VendorID and match any of the device
IDs against any of the metadata-supplied values.

eMMC Support

Introduction

This plugin reads the sysfs attributes corresponding to eMMC devices. It uses the kernel MMC API for flashing devices.

Protocol

eMMC devices support the org.jedec.mmc protocol.

GUID Generation

These devices use the following instance values:

  • EMMC\%NAME%
  • EMMC\%MANFID%&%OEMID%
  • EMMC\%MANFID%&%OEMID%&%NAME%

Vendor ID Security

The vendor ID is set from the EMMC vendor, for example set to EMMC:{$manfid}

External interface access

This plugin requires ioctl MMC_IOC_CMD and MMC_IOC_MULTI_CMD access.
