Tegra210 has a per-pin option named e_io_hv, which indicates that the
pin's input path should be configured to be 3.3v-tolerant. Add support
for this.
Note that this is very similar to previous chip's rcv_sel option.
However, since the Tegra TRM names this option differently for the
different chips, we support the new name so that the code exactly matches
the naming in the TRM, to avoid confusion.

Tegra's drive group registers have a remarkably inconsistent layout. The
current U-Boot driver doesn't take this into account at all. Add a
comment to describe the issue, so at least anyone debugging the driver
will be aware of this. To solve this, we'd need to add a per-drive-group
data structure describing the layout for the individual register. Since
we don't set up too many drive groups in U-Boot at present, this
hopefully isn't causing too much practical issue. Still, we probably need
to fix this sometime.
Wth Tegra210, the register layout becomes almost entirely consistent, so
this problem partially solves itself over time.

Syseng has revamped the Jetson TK1 pinmux spreadsheet, basing the content
completely on correct configuration for the board/schematic, rather than
the previous version which was based on the bare minimum changes relative
to another reference board.
The new spreadsheet sets TRISTATE for any input-only pins. This only works
correctly if the global CLAMP bit is not set, so the Jetson TK1 board code
has been adjusted accordingly. Apparently syseng have changed their mind
since the previous advice that this needed to be set:-/

When the CPU is in non-secure (NS) mode (when running U-Boot under a
secure monitor), certain actions cannot be taken, since they would need
to write to secure-only registers. One example is configuring the ARM
architectural timer's CNTFRQ register.
We could support this in one of two ways:
1) Compile twice, once for secure mode (in which case anything goes) and
once for non-secure mode (in which case certain actions are disabled).
This complicates things, since everyone needs to keep track of
different U-Boot binaries for different situations.
2) Detect NS mode at run-time, and optionally skip any impossible actions.
This has the advantage of a single U-Boot binary working in all cases.
(2) is not possible on ARM in general, since there's no architectural way
to detect secure-vs-non-secure. However, there is a Tegra-specific way to
detect this.
This patches uses that feature to detect secure vs. NS mode on Tegra, and
uses that to:
* Skip the ARM arch timer initialization.
* Set/clear an environment variable so that boot scripts can take
different action depending on which mode the CPU is in. This might be
something like:
if CPU is secure:
load secure monitor code into RAM.
boot secure monitor.
secure monitor will restart (a new copy of) U-Boot in NS mode.
else:
execute normal boot process

All boards need CONFIG_BOARD_EARLY_INIT_F, and many actively need
CONFIG_BOARD_LATE_INIT. Move both of these into tegra-common.h so that
board config headers don't need to repeatedly define them.
Later commits will add new code in board_late_init() which applies to
all boards, so CONFIG_BOARD_LATE_INIT should be enabled for all Tegra
boards.

Some systems have so much RAM that the end of RAM is beyond 4GB. An
example would be a Tegra124 system (where RAM starts at 2GB physical)
that has more than 2GB of RAM.
In this case, we want gd->ram_size to represent the actual RAM size, so
that the actual RAM size is passed to the OS. This is useful if the OS
implements LPAE, and can actually use the "extra" RAM.
However, we can't use get_ram_size() to verify the actual amount of RAM
present on such systems, since some of the RAM can't be accesses, which
confuses that function. Avoid calling get_ram_size() when the RAM size
is too large for it to work correctly. It's never actually needed anyway,
since there's no reason for the BCT to report the wrong RAM size.
In systems with >=4GB RAM, we still need to clip the reported RAM size
since U-Boot uses a 32-bit variable to represent the RAM size in bytes.

Freescale's SEC block has built-in Data Encryption
Key(DEK) Blob Protocol which provides a method for
protecting a DEK for non-secure memory storage.
SEC block protects data in a data structure called
a Secret Key Blob, which provides both confidentiality
and integrity protection.
Every time the blob encapsulation is executed,
a AES-256 key is randomly generated to encrypt the DEK.
This key is encrypted with the OTP Secret key
from SoC. The resulting blob consists of the encrypted
AES-256 key, the encrypted DEK, and a 16-bit MAC.
During decapsulation, the reverse process is performed
to get back the original DEK. A caveat to the blob
decapsulation process, is that the DEK is decrypted
in secure-memory and can only be read by FSL SEC HW.
The DEK is used to decrypt data during encrypted boot.
Commands added
--------------
dek_blob - encapsulating DEK as a cryptgraphic blob
Commands Syntax
---------------
dek_blob src dst len
Encapsulate and create blob of a len-bits DEK at
