This commit replaces hard-coded EMIF and PHY DDR3 configurations for
predefined SODIMMs to a calculated configuration. The SODIMM parameters
are read from SODIMM's SPD and used to calculated the configuration.
The current commit supports calculation for DDR3 with 1600MHz and 1333MHz
only.

The original name of this function is unclear. This patch renames this
CRC16 function to crc16_ccitt() matching its name with its
implementation.
To make the usage of this function more flexible, lets add the CRC start
value as parameter to this function. This way it can be used by other
functions requiring different start values than 0 as well.

This is based on the davinci da850evm. It can boot from either the
on-board 16MB flash or from a microSD card. It also reads board
information from an I2C EEPROM.
The EV3 itself initally boots from write-protected EEPROM, so no
u-boot SPL is needed.

Current AM57xx evm supports both BeagleBoard-X15
(http://beagleboard.org/x15) and AM57xx EVM
(http://www.ti.com/tool/tmdxevm5728).
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.

This provides a way to load a FIT containing U-Boot and a selection of device

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
and SPL.
Note: Masahiro's moveconfig.py script is amazing.

The existing function to add a new property to a tree being built requires
that the entire contents of the new property be passed in. For some
applications it is more convenient to be able to add the property contents
later, perhaps by reading from a file. This avoids double-buffering of the
contents.
Add a new function to support this and adust the existing fdt_property() to
use it.

When running sandbox, the following phases occur, each with different
malloc implementations or behaviors:
1) Dynamic linker execution, using the dynamic linker's own malloc()
implementation. This is fully functional.
2) After U-Boot's malloc symbol has been hooked into the GOT, but before
any U-Boot code has run. This phase is entirely non-functional, since
U-Boot's gd symbol is NULL and U-Boot's initf_malloc() and
mem_malloc_init() have not been called.
At least on Ubuntu Xenial, the dynamic linker does make both malloc() and
free() calls during this phase. Currently these free() calls crash since
they dereference gd, which is NULL.
U-Boot itself makes no use of malloc() during this phase.
3) U-Boot execution after gd is set and initf_malloc() has been called.
This is fully functional, albeit via a very simple malloc()
implementation.
4) U-Boot execution after mem_malloc_init() has been called. This is fully
functional with a complete malloc() implementation.
Furthermore, if code that called malloc() during phase 1 calls free() in
phase 3 or later, it is likely that heap corruption will occur, since
U-Boot's malloc implementation will assume the pointer is part of its own
heap, although it isn't. I have not actively observed this happening.
To prevent phase 2 from happening, this patch makes all of U-Boot's malloc
library public symbols have hidden visibility. This prevents them from
being hooked into the GOT, so only code in the U-Boot binary itself
actually calls them; any other code will call into the standard C library
malloc(). This also avoids the "furthermore" issue mentioned above.
I have seen references to this GCC pragma in blog posts from 2008, and
RHEL5's ancient gcc appears to accept it fine, so I believe it's quite
safe to use it without checking gcc version.

"fastboot oem format" command reuses "gpt write" command, which in turn
requires correct partitions defined in $partitions variable. This patch
adds such definition of Android partitions for DRA7XX EVM board.
By default $partitions variable contains Linux partition table. In order
to prepare Android environment one can run next commands from U-Boot
shell:
=> env set partitions $partitions_android
=> env save
After those operations one can go to fastboot mode and perform
"fastboot oem format" to create Android partition table.
While at it, enable CONFIG_RANDOM_UUID to spare user from providing
UUIDs for each partition manually.

A recent change broke the 'bootm' command on sandbox. The root cause is
using a pointer as an address. Conversion from pointer to address needs to
use map_to_sysmem() so that sandbox can do the right thing. The problem was
pre-existing but uncovered by a recent commit.
Fix this. Also move fit_get_end() to the C file to avoid needing to include
mapmem.h (and thus asm/io.h) everywhere.

During boot, U-Boot raises the CPU frequency but the CORE and MPU regulators
are not updated. This is not a problem in cold boot since the default values
that the pmic outputs are correct, but if Linux were to switch the module to a
low power OPP, the new voltage values will be retained after a reboot and the
module will likely hang once U-Boot raises the CPU frequency back up.
Set both CORE and MPU regulators to to 1.1V on boot.

In future we want to bring up boards which are not based on AM335x only
but we still want to have common configuration over all B&R boards
independent from their architecture.
To prepare this we introduce a new file "bur_cfg_common.h", where we

bur_am335x_common.h.
On B&R am335x boards we include from now:
