README.Heterogeneous-SoCs

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
