Broadcom 95xx BMW CPCI Platform
Overview
=========
BMW is an MPC8245 system controller featuring:
* 3U CPCI Form Factor
* BCM5703 Gigabit Ethernet
* M48T59Y NVRAM
* 16MB DOC
* DIP Socket for Socketed DOC up to 1GB
* 64MB SDRAM
* LCD Display
* Configurable Jumper options for 66,85, and 100Mhz memory bus
BMW System Address Map
======================
BMW uses the MPC8245 CHRP Address MAP B found in the MPC8245 Users Manual
(P.121, Section 3.1 Address Maps, Address Map B). Other I/O devices found
onboard the processor module are listed briefly below:
0x00000000 - 0x40000000 - 64MB SDRAM SIMM
(Unregistered PC-100 SDRAM DIMM Module)
0xFF000000 - 0xFF001FFF - M-Systems DiskOnChip (TM) 2000
TSOP 16MB (MD2211-D16-V3)
0x70000000 - 0x70001FFF - M-Systems DiskOnChip (TM) 2000
DIP32 (Socketed 16MB - 1GB ) *
NOTE: this is not populated on all systems.
0x7c000000 - 0x7c000000 - Reset Register
(Write 0 to reset)
0x7c000001 - 0x7c000001 - System LED
(Clear Bit 7 to turn on, set to shut off)
0x7c000002 - 0x7c000002 - M48T59 Watchdog IRQ3
(Clear bit 7 to reset, set to assert IRQ3)
0x7c000003 - 0x7c000003 - M48T59 Write-Protect Register
(Clear bit 7 to make R/W, set to make R/O)
0x7c002000 - 0x7c002003 - Infineon OSRAM DLR2416 4 Character
5x7 Dot Matrix Alphanumeric Display
(Each byte sets the appropriate character)
0x7c004000 - 0x7c005FF0 - SGS-THOMSON M48T59Y 8K NVRAM/RTC
NVRAM Memory Region
0x7c005FF0 - 0x7c005FFF - SGS-THOMSON M48T59Y 8K NVRAM/RTC
Realtime Clock Registers
0xFFF00000 - 0xFFF80000 - 512K PLCC32 BootRom
(AMD AM29F040, ST 29W040B)
0xFFF00100 - System Reset Vector
IO/MMU (BAT) Configuration
======================
The following Block-Address-Translation (BAT) configuration
is recommended to access all I/O devices.
#define CFG_IBAT0L (0x00000000 | BATL_PP_10 | BATL_MEMCOHERENCE)
#define CFG_IBAT0U (0x00000000 | BATU_BL_256M | BATU_VS | BATU_VP)
#define CFG_IBAT1L (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
#define CFG_IBAT1U (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP)
#define CFG_IBAT2L (0x80000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
#define CFG_IBAT2U (0x80000000 | BATU_BL_256M | BATU_VS | BATU_VP)
#define CFG_IBAT3L (0xF0000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
#define CFG_IBAT3U (0xF0000000 | BATU_BL_256M | BATU_VS | BATU_VP)
#define CFG_DBAT0L CFG_IBAT0L
#define CFG_DBAT0U CFG_IBAT0U
#define CFG_DBAT1L CFG_IBAT1L
#define CFG_DBAT1U CFG_IBAT1U
#define CFG_DBAT2L CFG_IBAT2L
#define CFG_DBAT2U CFG_IBAT2U
#define CFG_DBAT3L CFG_IBAT3L
#define CFG_DBAT3U CFG_IBAT3U
Interrupt Mappings
======================
BMW uses MPC8245 discrete mode interrupts. With the following
hardwired mappings:
BCM5701 10/100/1000 Ethernet IRQ1
CompactPCI Interrupt A IRQ2
RTC/Watchdog Interrupt IRQ3
Internal NS16552 UART IRQ4
Jumper Settings
======================
BMW has a jumper (JP600) for selecting 66, 85, or 100Mhz memory bus.
A jumper (X) is a 0 bit.
Hence 66= 10110
85= 11000
100= 10000
Jumper Settings for various Speeds
=======================
J1 J2 J3 J4 J5
X X 66Mhz
=======================
J1 J2 J3 J4 J5
X X X 85Mhz
=======================
J1 J2 J3 J4 J5
X X X X 100Mhz
=======================
Obviously, 100Mhz memory bus is recommended for optimum performance.
U-Boot
===============
Broadcom BMW board is supported under config_BWM option.
Supported features:
- NVRAM setenv/getenv (used by Linux Kernel for configuration variables)
- BCM570x TFTP file transfer support
