Richard Hughes 2e1245728f Call the superclass directly from subclassed devices
This allows a device subclass to call the parent method after doing an initial
action, or even deliberately not call the *generic* parent method at all.

It also simplifies the plugins; you no longer have to remember what the plugin
is deriving from and accidentally clobber the wrong superclass method.

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.
