Subject: warp: Add initial WaRP Board support

The WaRP Board is a Wearable Reference Plaform. The board features:

 - Freescale i.MX6 SoloLite processor with 512MB of RAM
 - Freescale FXOS8700CQ 6-axis Xtrinsic sensor
 - Freescale Kinetis KL16 MCU
 - Freescale Xtrinsic MMA955xL intelligent motion sensing platform

The board implements a hybrid architecture to address the evolving
needs of the wearables market. The platform consists of a main board
and an example daughtercard with the ability to add additional
daughtercards for different usage models.

For more information about the project, visit:

 http://www.warpboard.org/

From: Raul Cardenas <Ulises.Cardenas@freescale.com>
Date: Fri, 27 Feb 2015 11:22:06 -0600
Subject: imx6: Added DEK blob generator command

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
    address src and store the result at address dst.

 NOTE: U-Boot_CSF.bin needs to be padded to the value specified in

+
+Setup U-Boot Image for Encrypted Boot
+-------------------------------------
+An authenticated U-Boot image is used as starting point for
+Encrypted Boot. The image is encrypted by Freescale's Code
+Signing Tool (CST). The CST replaces only the image data of
+u-boot.imx with the encrypted data. The Initial Vector Table,
+DCD, and Boot data, remains in plaintext.
+
+The image data is encrypted with a Encryption Key (DEK).
+Therefore, this key is needed to decrypt the data during the
+booting process. The DEK is protected by wrapping it in a Blob,
+which needs to be appended to the U-Boot image and specified in
+the CSF file.
+
+The DEK blob is generated by an authenticated U-Boot image with
+the dek_blob cmd enabled. The image used for DEK blob generation
+needs to have the following configurations enabled:
+
+CONFIG_SECURE_BOOT
+CONFIG_SYS_FSL_SEC_COMPAT    4 /* HAB version */
+CONFIG_FSL_CAAM
+CONFIG_CMD_DEKBLOB
+
+Note: The encrypted boot feature is only supported by HABv4 or
+greater.
+
+The dek_blob command then can be used to generate the DEK blob of
+a DEK previously loaded in memory. The command is used as follows:
+
+dek_blob <DEK address> <Output Address> <Key Size in Bits>
+example: dek_blob 0x10800000 0x10801000 192
+
+The resulting DEK blob then is used to construct the encrypted
+U-Boot image. Note that the blob needs to be transferred back
+to the host.Then the following commands are used to construct
+the final image.
+
+objcopy -I binary -O binary --pad-to 0x2000 --gap-fill=0x00 \
+    U-Boot_CSF.bin U-Boot_CSF_pad.bin
+cat u-boot.imx U-Boot_CSF_pad.bin > u-boot-signed.imx
+objcopy -I binary -O binary --pad-to <blob_dst> --gap-fill=0x00 \
+    u-boot-signed.imx u-boot-signed-pad.bin
+cat u-boot-signed-pad.imx DEK_blob.bin > u-boot-encrypted.imx
+
+    NOTE: u-boot-signed.bin needs to be padded to the value
+    equivalent to the address in which the DEK blob is specified
+    in the CSF.

With UMS support we are able to flash the eMMC from U-boot, which is very
convenient.

Add UMS support to make the eMMC flashing process easier.

Subject: mx5: fix get_reset_cause

commit d9f43c8f5c1d7ed27c99a06be85a4bb64b2c73fb sets
get_reset_cause() as static, but this conflicts with mx5
where its prototype is in sys_proto.h.

Drop it from sys_proto.h and drop print_cpuinfo from mx53_loco,
factorizing the call for this board.
