Supported Boot Devices
======================

The OpenPower firmware uses Linux as a bootloader in order to discover boot
devices, and boot the final operating system. In order to discover boot devices
and load the operating system image from them, the bootloader's kernel needs to
include support for that hardware.

This table lists the network adaptors and disk controllers that are currently
enabled.

If you are adding a device to the kernel, please add the details here including
your email address in the owner field. We will use this to contact users when
considering the removal of modules.

Likewise, if you are removing an option from the kernel config, please remove
it from this table and notify the person mentioned in the owner field.
