This patch adds the support for VID on LS1088AQDS and LS1088ARDB systems.
It reads the fusesr register and changes the VDD accordingly by adjusting
the voltage via LTC3882 regulator.
This patch also takes care of the special case of 0.9V VDD is present in
fusesr register. In that case,it also changes the SERDES voltage by
disabling the SERDES, changing the SVDD and then re-enabling SERDES.

This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices
For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol
The uclass provides the bind, start, and stop entry points for the driver
binding protocol.
In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.
The EFI block driver binds to controllers implementing the block io
protocol.
When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.
The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.
A usage example is as following:
U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.
Now the EFI block driver installs the partitions with the simple file
protocol.
iPXE uses the simple file protocol to load Grub or the Linux Kernel.

Some distributions like Fedora expect U-Boot to select a proper

featuring different SoC variants and the module can be paired with
several baseboards, it is not viable to hardcode a filename.
Instead, follow the lead of other i.MX6 based devices and try to
determine the devicetree to use with the help of the board name
and the SoC variant exported by the board code, before calling the
distro bootcommand.
For now, only for the Utilite Pro a proper devicetree filename is
known but further variants of the Utilite Computer or other devices
based on the cm-fx6 module may be added in the future.

Like many other i.MX6 based boards, there are multiple variants of
the cm-fx6 module featuring different SoC variants. Furthermore, the
module can be paired with multiple baseboards.
At the same time modern distribution like Fedora require U-Boot to
select a proper devicetree which depends on the SoC variant and the
baseboard.
Thus, export the SoC variant and the actual board to the environment
following the conventions of other i.MX6 devices (e.g. the NXP boards)
such that the environment can select a devicetree file to load.
For now, we only know for sure that the cm-fx6 module and the SB-fx6m
baseboard amount to a Utilite Computer variant (depending on the SoC).
Further combinations may be added in the future; e.g. CompuLab's

With certain SD cards like Kingston 8GB/16GB UHS card, it is seen that
MMC_CMD_ALL_SEND_CID cmd fails on first attempt, but succeeds
subsequently. Therefore, retry MMC_CMD_ALL_SEND_CID cmd a few time
as done in Linux kernel.
Similarly, it is seen that MMC_CMD_SET_BLOCKLEN may fail on first
attempt, therefore retry this cmd a few times as done in kernel.
To make it clear that those are optionnal workarounds, a new Kconfig
option 'MMC_QUIRKS' is added (enabled by default).

Boot partitions do not support HS200. Changing to a lower performance mode
is required to access them.
mmc_select_mode_and_width() and sd_select_mode_and_width() are modified to
make it easier to call them outside of the initialization context.

If a power cycle cannot be done on Vcc, it is safer not to try the UHS
modes because we wouldn't be able to recover from an error occurring
during the UHS initialization.

Add UHS modes to the list of supported modes, get the UHS capabilites of
the SDcard and implement the procedure to switch the voltage (UHS modes
use 1v8 IO lines)
During the voltage switch procedure, DAT0 is used by the card to signal
when it's ready. The optional card_busy() callback can be used to get this
information from the host driver.

to take disable as an argument that signifies if the

Add a new callback function *send_init_stream* which start a sequence of
at least 74 clock cycles.
The mmc core uses *mmc_send_init_stream* in order to invoke the callback
function. This will be used during power cycle where the specification
requires such a sequence after power up.
