This patch does the following:
1. The function names for encapsulation and decapsulation
were inconsitent in freescale's implementation and cmd_blob file.
This patch corrects the issues.
2. The function protopye is also modified to change the length parameter
from u8 to u32 to allow encapsulation and decapsulation of larger images.
3. Modified the description of km paramter in the command usage for better
readability.

Era property is added in the crypto node in device tree.
Move the code to do so from arch/powerpc/mpc8xxx/fdt.c to
drivers/sec/sec.c so that it can be used across arm and
powerpc platforms having crypto node.

Corrected the order of arguments in memset in run_descriptor
function. Wrong order of argumnets led to improper initialization
of members of struct type result. This resulted in RNG instantiation
error.

Freescale's SEC block has built-in Blob Protocol which provides
a method for protecting user-defined data across system power
cycles. SEC block protects data in a data structure called a Blob,
which provides both confidentiality and integrity protection.
Encapsulating data as a blob
Each time that the Blob Protocol is used to protect data, a
different randomly generated key is used to encrypt the data.
This random key is itself encrypted using a key which is derived
from SoC's non volatile secret key and a 16 bit Key identifier.
The resulting encrypted key along with encrypted data is called a blob.
The non volatile secure key is available for use only during secure boot.
During decapsulation, the reverse process is performed to get back
the original data.
Commands added
--------------
blob enc - encapsulating data as a cryptgraphic blob
blob dec - decapsulating cryptgraphic blob to get the data
Commands Syntax
---------------
blob enc src dst len km
Encapsulate and create blob of data $len bytes long
at address $src and store the result at address $dst.
$km is the 16 byte key modifier is also required for
generation/use as key for cryptographic operation. Key
modifier should be 16 byte long.
blob dec src dst len km
Decapsulate the blob of data at address $src and
store result of $len byte at addr $dst.
$km is the 16 byte key modifier is also required for
generation/use as key for cryptographic operation. Key
modifier should be 16 byte long.

SHA-256 and SHA-1 accelerated using SEC hardware in Freescale SoC's
The driver for SEC (CAAM) IP is based on linux drivers/crypto/caam.
The platforms needto add the MACRO CONFIG_FSL_CAAM inorder to
enable initialization of this hardware IP.

commit 18b06652cd "tools: include u-boot version of sha256.h"
unconditionally forced the sha256.h from u-boot to be used
for tools instead of the host version. This is fragile though
as it will also include the host version. Therefore move it
to include/u-boot to join u-boot/md5.h etc which were renamed
for the same reason.

This patch adds implementation of rand library based on hardware random
number generator of security subsystem in Exynos SOC.
This library includes:
- srand() - used for seed hardware block
- rand() - returns random number
- rand_r() - the same as above with given seed
which depends on CONFIG_EXYNOS_ACE_SHA and CONFIG_LIB_HW_RAND.
