From 35fe948e3b62789182610f57d48f97dbd5403aa8 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Wed, 23 Jan 2013 17:59:57 +0000 Subject: powerpc/mpc85xx: Add BSC9132/BSC9232 processor support The BSC9132 is a highly integrated device that targets the evolving Microcell, Picocell, and Enterprise-Femto base station market subsegments. The BSC9132 device combines Power Architecture e500 and DSP StarCore SC3850 core technologies with MAPLE-B2P baseband acceleration processing elements to address the need for a high performance, low cost, integrated solution that handles all required processing layers without the need for an external device except for an RF transceiver or, in a Micro base station configuration, a host device that handles the L3/L4 and handover between sectors. The BSC9132 SoC includes the following function and features: - Power Architecture subsystem including two e500 processors with 512-Kbyte shared L2 cache - Two StarCore SC3850 DSP subsystems, each with a 512-Kbyte private L2 cache - 32 Kbyte of shared M3 memory - The Multi Accelerator Platform Engine for Pico BaseStation Baseband Processing (MAPLE-B2P) - Two DDR3/3L memory interfaces with 32-bit data width (40 bits including ECC), up to 1333 MHz data rate - Dedicated security engine featuring trusted boot - Two DMA controllers - OCNDMA with four bidirectional channels - SysDMA with sixteen bidirectional channels - Interfaces - Four-lane SerDes PHY - PCI Express controller complies with the PEX Specification-Rev 2.0 - Two Common Public Radio Interface (CPRI) controller lanes - High-speed USB 2.0 host and device controller with ULPI interface - Enhanced secure digital (SD/MMC) host controller (eSDHC) - Antenna interface controller (AIC), supporting four industry standard JESD207/four custom ADI RF interfaces - ADI lanes support both full duplex FDD support & half duplex TDD - Universal Subscriber Identity Module (USIM) interface that facilitates communication to SIM cards or Eurochip pre-paid phone cards - Two DUART, two eSPI, and two I2C controllers - Integrated Flash memory controller (IFC) - GPIO - Sixteen 32-bit timers Signed-off-by: Naveen Burmi Signed-off-by: Poonam Aggrwal Signed-off-by: Prabhakar Kushwaha Signed-off-by: Andy Fleming --- arch/powerpc/cpu/mpc85xx/bsc9132_serdes.c | 96 +++++++++++++++++++++++++++++++ 1 file changed, 96 insertions(+) create mode 100644 arch/powerpc/cpu/mpc85xx/bsc9132_serdes.c (limited to 'arch/powerpc/cpu/mpc85xx/bsc9132_serdes.c') diff --git a/arch/powerpc/cpu/mpc85xx/bsc9132_serdes.c b/arch/powerpc/cpu/mpc85xx/bsc9132_serdes.c new file mode 100644 index 0000000..300a4db --- /dev/null +++ b/arch/powerpc/cpu/mpc85xx/bsc9132_serdes.c @@ -0,0 +1,96 @@ +/* + * Copyright 2013 Freescale Semiconductor, Inc. + * Author: Prabhakar Kushwaha + * + * This program is free software;
