The commonly defined environment variable to determine the device tree
file name is called fdtfile rather than fdt_name. Replace all occurences
of fdt_name with fdtfile.

UEFI defines a simple boot protocol for removable media. There we should look
at the EFI (first GPT FAT) partition and search for /efi/boot/bootXXX.efi with
XXX being different between different platforms (x86, x64, arm, aa64, ...).
This patch implements a simple version of that protocol for the default distro
boot script. With this we can automatically boot from valid UEFI enabled
removable media.
Because from all I could see U-Boot by default doesn't deliver device tree
blobs with its firmware, we also need to load the dtb from somewhere. Traverse
the same EFI partition for an fdt file that fits our current board so that
an OS receives a valid device tree when booted automatically.

The EFI loader needs to maintain views of memory - general system memory
windows as well as used locations inside those and potential runtime service
MMIO windows.
To manage all of these, add a few helpers that maintain an internal
representation of the map the similar to how the EFI API later on reports
it to the application.
For allocations, the scheme is very simple. We basically allow allocations
to replace chunks of previously done maps, so that a new LOADER_DATA
allocation for example can remove a piece of the RAM map. When no specific
address is given, we just take the highest possible address in the lowest
RAM map that fits the allocation size.

A EFI applications usually want to access storage devices to load data from.
This patch adds support for EFI disk interfaces. It loops through all block
storage interfaces known to U-Boot and creates an EFI object for each existing
one. EFI applications can then through these objects call U-Boot's read and
write functions.

After booting has finished, EFI allows firmware to still interact with the OS
using the "runtime services". These callbacks live in a separate address space,
since they are available long after U-Boot has been overwritten by the OS.
This patch adds enough framework for arbitrary code inside of U-Boot to become
a runtime service with the right section attributes set. For now, we don't make
use of it yet though.
We could maybe in the future map U-boot environment variables to EFI variables
here.

One of the basic EFI interfaces is the console interface. Using it an EFI
application can interface with the user. This patch implements an EFI console
interface using getc() and putc().
Today, we only implement text based consoles. We also convert the EFI Unicode
characters to UTF-8 on the fly, hoping that everyone managed to jump on the
train by now.

When an EFI application runs, it has access to a few descriptor and callback
tables to instruct the EFI compliant firmware to do things for it. The bulk
of those interfaces are "boot time services". They handle all object management,
and memory allocation.
This patch adds support for the boot time services and also exposes a system
table, which is the point of entry descriptor table for EFI payloads.

The EFI API header is great, but missing a good chunk of function prototype,

We have a pretty nice and generic interface to ask for a specific block
device. However, that one is still based around the magic notion that
we know the driver name.
In order to be able to write fully generic disk access code, expose the
currently internal list to other source files so that they can scan through
all available block drivers.

By now the code to only have a single page table level with 64k page

The idea to generate our pages tables from an array of memory ranges
is very sound. However, instead of hard coding the code to create up
to 2 levels of 64k granule page tables, we really should just create
normal 4k page tables that allow us to set caching attributes on 2M
or 4k level later on.
So this patch moves the full_va mapping code to 4k page size and
makes it fully flexible to dynamically create as many levels as
necessary for a map (including dynamic 1G/2M pages). It also adds
support to dynamically split a large map into smaller ones when
some code wants to set dcache attributes.
With all this in place, there is very little reason to create your
own page tables in board specific files.

When booting from USB, the bootrom sets the VUSB_IN_PMID bit of the MISC2
register of the TWL6030. However, U-Boot sets the VUSB_IN_VSYS bit to enable
VBUS input. As both bits are contradictory, enabling both disables the input,
according to the TWL6030 TRM.
Thus, we need to clear the VUSB_IN_PMID bit in case of an USB boot (which could
just as well be a memory boot after USB timed out).

Current AM57xx evm supports both BeagleBoard-X15
(http://beagleboard.org/x15) and AM57xx EVM

The AM572x EValuation Module(EVM) provides an affordable platform to
quickly start evaluation of Sitara. ARM Cortex-A15 AM57x Processors
(AM5728, AM5726, AM5718, AM5716) and accelerate development for HMI,
machine vision, networking, medical imaging and many other industrial
applications. This EVM is based on the same BeagleBoard-X15 Chassis
and adds mPCIe, mSATA, LCD, touchscreen, Camera, push button and TI's
wlink8 offering.
Since the EEPROM contents are compatible between the BeagleBoard-X15 and
the AM57xx-evm, we add support for the detection logic to enable
support for various user programmable scripting capability.
NOTE: U-boot configuration is currently a superset of AM57xx evm and
BeagleBoard-X15 and no additional configuration tweaking is needed.
This change also sets up the stage for future support of TI AM57xx EVMs
to the same base bootloader build.

There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.
Move these options to Kconfig and tidy up board configuration:
CONFIG_FIT
CONFIG_OF_BOARD_SETUP
CONFIG_OF_SYSTEM_SETUP
CONFIG_FIT_SIGNATURE
CONFIG_FIT_BEST_MATCH
CONFIG_FIT_VERBOSE
CONFIG_OF_STDOUT_VIA_ALIAS
CONFIG_RSA
Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
