Overview
--------
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

- 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

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
The SC3850 core subsystem consists of the following:
- 32 KB, 8-way, level 1 instruction cache (L1 ICache)
- 32 KB, 8-way, level 1 data cache (L1 DCache)
- 512 KB, 8-way, level 2 unified instruction/data cache (L2 cache/M2 memory)
- Memory management unit (MMU)
- Global interrupt controller ( GIC)
- Debug and profiling unit (DPU)
- Two 32-bit quad timers

Flashing Images
---------------
To place a new U-Boot image in the NAND flash and then boot
with that new image temporarily, use this:
tftp 1000000 u-boot-nand.bin
nand erase 0 100000
nand write 1000000 0 100000
reset
Using the Device Tree Source File
---------------------------------
To create the DTB (Device Tree Binary) image file,
use a command similar to this:
dtc -b 0 -f -I dts -O dtb bsc9132qds.dts > bsc9132qds.dtb
Likely, that .dts file will come from here;
linux-2.6/arch/powerpc/boot/dts/bsc9132qds.dts
Booting Linux
-------------
Place a linux uImage in the TFTP disk area.
tftp 1000000 uImage
tftp 2000000 rootfs.ext2.gz.uboot
tftp c00000 bsc9132qds.dtb
bootm 1000000 2000000 c00000
