6700874deb Block drivers: make IOCTL request unsigned long
The block driver protocol and libblockdriver's bdr_ioctl hook are
changed, as well as the users of this hook. Other parts of the system
are expected to change accordingly eventually, since the ioctl(2)
prototype has been aligned with NetBSD's.

95624ae072 Block protocol: add user endpoint to IOCTL request
I/O control requests now come with the endpoint of the user process
that initiated the ioctl(2) call. It is stored in a new BDEV_USER
field, which is an alias for BDEV_FLAGS. The contents of this field
are to be used only in highly specific situations. It should be
preserved (not replaced!) by services that forward IOCTL requests,
and may be set to NONE for service-initiated IOCTL requests.

7d85156ac0 arm:mmc driver refactor (use structs)
Defined register offsets and device configurations in structs to
allow more flexibility. This change will allow to support multiple
instances of a driver using a different bus. This is needed for the
BeagleBone Black.

061fed753e arm:mmc driver refactor and timeout fix for BeagleBoneBlack.
When we send MMC commads that contain data the controller provides no
description of the order of events and we need to be able to send data
from and to the controller "when needed". Changed the code to react
on buffer read and buffer write ready based on interrupts.

718114d9b0 arm:mmc driver refactor.
Generalize the usage of mmc_send_cmd function to allow
it to transfer data and remove direct invocations to
mmchs_send_cmd.
