Add the 2048 game, a good demo of ANSI sequences and a way to waste a
little time.

Bring it it from Barebox, modified for code style.

Add a frontend for the blkmap subsystem. In addition to the common
block device operations, this allows users to create and destroy
devices, and map in memory and slices of other block devices.

With that we support two primary use-cases:

- Being able to "distro boot" from a RAM disk. I.e., from an image
  where the kernel is stored in /boot of some filesystem supported
  by U-Boot.

- Accessing filesystems not located on exact partition boundaries,
  e.g. when a filesystem image is wrapped in an FIT image and stored
  in a disk partition.

Enable tuning of the PCI Express MPS (Maximum Payload Size) of
each device. The Maximum Read Request Size is not altered.

The SAFE method uses the largest MPS value supported by all devices in the
system for each device. This method is the same algorithm as used by Linux
pci=pcie_bus_safe.

The PEER2PEER method sets all devices to the minimal (128 byte) MPS, which
allows hot plug of devices later that might only support the minimum size,
and ensures compatibility of DMA between two devices on the bus.

Add a command (for the app and payload) to display the tables provided
by EFI. Note that for the payload the tables should always be present, so
an error message is unnecessary and would bloat the code.

This code is used with EFI_LOADER but is also useful (with some
modifications) for the EFI app and payload. Move it into a shared
file.

Show the address of the table so it can be examined if needed. Also show
the table name as unknown if necessary. Our list of GUIDs is fairly
small.

It's almost no extra code to hook up a buddy to the 'read' command. In
fact, since the command is passed its own 'struct cmd_tbl', we can use
the exact same callback, and let it figure out for itself whether it
was invoked as "read" or "write".

Allow font size configuration at runtime for console_simple.c
driver. This needed for unit testing different fonts.

Configuring is done by `font` command, also used for font
selection in true type console.

Add a command to load SEAMA (Seattle Image), a NAND flash
on-flash storage format.

This type of flash image is found in some D-Link routers such
as DIR-645, DIR-842, DIR-859, DIR-860L, DIR-885L, DIR890L and
DCH-M225, as well as in WD and NEC routers on the ath79
(MIPS), Broadcom BCM53xx, and RAMIPS platforms.

This U-Boot command will read and decode a SEAMA image from
raw NAND flash on any platform. As it is always using big endian
format for the data decoding is always necessary on platforms
such as ARM.

The command is needed to read a SEAMA-encoded boot image on the
D-Link DIR-890L router for boot from NAND flash in an upcoming
port of U-Boot to the Broadcom Northstar (BCM4709, BCM53xx)
architecture.

A basic test and documentation is added as well. The test must
be run on a target with NAND flash support and at least one
resident SEAMA image in flash.
