dma: keystone_nav: generalize driver usage
The keystone_nav driver is general driver intended to be used for
working with queue manager and pktdma for different IPs like NETCP,
AIF, FFTC, etc. So the it's API shouldn't be named like it works only
with one of them, it should be general names. The names with prefix
like netcp_* rather do for drivers/net/keystone_net.c driver. So it's
good to generalize this driver to be used for different IP's and

The current netcp_* functions of keystone navigator can be used for
other settings of pktdma, not only for NETCP. The API of this driver
is used by the keystone_net driver to work with NETCP, so net driver

dm: add of_match_ptr() macro
The driver model supports two ways for passing device parameters;
Device Tree and platform_data (board file).
Each driver should generally support both of them because some
popular IPs are used on various platforms.
Assume the following scenario:
- The driver Foo is used on SoC Bar and SoC Baz
- The SoC Bar uses Device Tree control (CONFIG_OF_CONTROL=y)
- The SoC Baz does not support Device Tree; uses a board file
In this situation, the device driver Foo should work with/without
the device tree control. The driver should have .of_match and
.ofdata_to_platdata members for SoC Bar, while they are meaningless
for SoC Baz; therefore those device-tree control code should go
inside #ifdef CONFIG_OF_CONTROL.
The driver code will be like this:
#ifdef CONFIG_OF_CONTROL
static const struct udevice_id foo_of_match = {
{ .compatible = "foo_driver" },
{},
}
static int foo_ofdata_to_platdata(struct udevice *dev)
{
...
}
#endif
U_BOOT_DRIVER(foo_driver) = {
...
.of_match = of_match_ptr(foo_of_match),
.ofdata_to_platdata = of_match_ptr(foo_ofdata_to_platdata),
...
}
This idea has been borrowed from Linux.

crypto/fsl: Add command for encapsulating/decapsulating blobs
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
