From 7428f55c94ac51214038a3882630ddb89520e42e Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Tue, 27 Jan 2015 10:14:03 +0800 Subject: pmic:pfuze implement pmic_mode_init This patch is to implement pmic_mode_init function, and add prototype in header file. This function is to set switching mode for pmic buck regulators to improve system efficiency. Mode: OFF: The regulator is switched off and the output voltage is discharged. PFM: In this mode, the regulator is always in PFM mode, which is useful at light loads for optimized efficiency. PWM: In this mode, the regulator is always in PWM mode operation regardless of load conditions. APS: In this mode, the regulator moves automatically between pulse skipping mode and PWM mode depending on load conditions.

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.
