+DSP side awareness for Freescale heterogeneous multicore chips based on
+StarCore and Power Architecture
+===============================================================
+powerpc/mpc85xx code ve APIs and function to get the number,
+configuration and frequencies of all PowerPC cores and devices
+connected to them, but it didnt have the similar code ofr HEterogeneous
+SC3900/DSP cores and such devices like CPRI, MAPLE, MAPLE-ULB etc.
+
+Code for DSP side awareness provides such functionality for Freescale
+Heterogeneous SoCs which are chasis-2 compliant like B4860 and B4420
+
+As part of this feature, following changes have been made:
+==========================================================
+
+1. Changed files:
+=================
+- arch/powerpc/cpu/mpc85xx/cpu.c
+
+Code added in this file to print the DSP cores and other device's(CPRI,
+MAPLE etc) frequencies
+
+- arch/powerpc/cpu/mpc85xx/speed.c
+
+Added Defines and code to extract the frequncy information for all
+required cores and devices from RCW and System frequency
+
+- arch/powerpc/cpu/mpc8xxx/cpu.c
+
+Added API to get the number of SC cores in running system and Their BIT
+MASK, similar to the code written for PowerPC
+
+- arch/powerpc/include/asm/config_mpc85xx.h
+
+Added top level CONFIG to identify presence of HETEROGENUOUS clusters
+in the system and CONFIGS for SC3900/DSP components
+
+- arch/powerpc/include/asm/processor.h
+- include/common.h
+
+Added newly added Functions Declaration
+
+- include/e500.h
+
+Global structure updated for dsp cores and other components
+
+2. CONFIGs ADDED
+================
+
+CONFIG_HETROGENOUS_CLUSTERS	- Define for checking the presence of
+				  DSP/SC3900 core clusters
+
+CONFIG_SYS_FSL_NUM_CC_PLLS	- Define for number of PLLs
+
+Though there are only 4 PLLs in B4, but in sequence of PLLs from PLL1 -
+PLL5, PLL3 is Reserved(as mentioned in RM), so this define contains the
+value as 5 not 4, to iterate over all PLLs while coding
+
+CONFIG_SYS_MAPLE		- Define for MAPLE Baseband Accelerator
+CONFIG_SYS_CPRI			- Define for CPRI Interface
+CONFIG_PPC_CLUSTER_START	- Start index of ppc clusters
+CONFIG_DSP_CLUSTER_START	- Start index of dsp clusters
+
+Following are the defines for PLL's index that provide the Clocking to
+CPRI, ULB and ETVE components
+
+CONFIG_SYS_CPRI_CLK		- Define PLL index for CPRI clock
+CONFIG_SYS_ULB_CLK		- Define PLL index for ULB clock
+CONFIG_SYS_ETVPE_CLK		- Define PLL index for ETVPE clock
+
+3. Changes in MPC85xx_SYS_INFO Global structure
+===============================================
+
+DSP cores and other device's components have been added in this structure.
+
+freq_processor_dsp[CONFIG_MAX_DSP_CPUS]	- Array to contain the DSP core's frequencies
+freq_cpri				- To store CPRI frequency
+freq_maple				- To store MAPLE frequency
+freq_maple_ulb				- To store MAPLE-ULB frequency
+freq_maple_etvpe			- To store MAPLE-eTVPE frequency

+
+esbc_validate command
+========================================
+
+1. esbc_validate command is meant for validating header and
+    signature of images (Boot Script and ESBC uboot client).
+    SHA-256 and RSA operations are performed using SEC block in HW.
+    This command works on both PBL based and Non PBL based Freescale
+    platforms.
+   Command usage:
+    esbc_validate img_hdr_addr [pub_key_hash]
+    esbc_validate hdr_addr <hash_val>
+     Validates signature using RSA verification.
+     $hdr_addr Address of header of the image to be validated.
+     $hash_val -Optional. It provides Hash of public/srk key to be
+       used to verify signature.
+
+2. ESBC uboot client can be linux. Additionally, rootfs and device
+    tree blob can also be signed.
+3. In the event of header or signature failure in validation,
+    ITS and ITF bits determine further course of action.
+4. In case of soft failure, appropriate error is dumped on console.
+5. In case of hard failure, SoC is issued RESET REQUEST after
+    dumping error on the console.
+6. KEY REVOCATION Feature:
+    QorIQ platforms like B4/T4 have support of srk key table and key
+    revocation in ISBC code in Silicon.
+    The srk key table allows the user to have a key table with multiple
+    keys and revoke any key in case of particular key gets compromised.
+    In case the ISBC code uses the key revocation and srk key table to
+    verify the u-boot code, the subsequent chain of trust should also
+    use the same.
+6. ISBC KEY EXTENSION Feature:
+    This feature allows large number of keys to be used for esbc validation
+    of images. A set of public keys is being signed and validated by ISBC
+    which can be further used for esbc validation of images.
