10 years agodm: add of_match_ptr() macro
Masahiro Yamada [Tue, 7 Oct 2014 05:51:31 +0000 (14:51 +0900)]
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
---------------

$km is the 16 byte key modifier is also required for

Also correct some typos. For now the Edison evaluation board is
added, README for K2E is mostly the same, so update README to
