Clean up Makefile, and drop a lot of the config.mk files on the way. We now also automatically pick all boards that are listed in boards.cfg (and with all configurations), so we can drop the redundant entries from MAKEALL to avoid building these twice. Signed-off-by: Wolfgang Denk <wd@denx.de> |

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 CONFIG_SYS_IBAT0L (0x00000000 | BATL_PP_10 | BATL_MEMCOHERENCE) #define CONFIG_SYS_IBAT0U (0x00000000 | BATU_BL_256M | BATU_VS | BATU_VP) #define CONFIG_SYS_IBAT1L (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT) #define CONFIG_SYS_IBAT1U (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP) #define CONFIG_SYS_IBAT2L (0x80000000 | BATL_PP_10 | BATL_CACHEINHIBIT) #define CONFIG_SYS_IBAT2U (0x80000000 | BATU_BL_256M | BATU_VS | BATU_VP) #define CONFIG_SYS_IBAT3L (0xF0000000 | BATL_PP_10 | BATL_CACHEINHIBIT) #define CONFIG_SYS_IBAT3U (0xF0000000 | BATU_BL_256M | BATU_VS | BATU_VP) #define CONFIG_SYS_DBAT0L CONFIG_SYS_IBAT0L #define CONFIG_SYS_DBAT0U CONFIG_SYS_IBAT0U #define CONFIG_SYS_DBAT1L CONFIG_SYS_IBAT1L #define CONFIG_SYS_DBAT1U CONFIG_SYS_IBAT1U #define CONFIG_SYS_DBAT2L CONFIG_SYS_IBAT2L #define CONFIG_SYS_DBAT2U CONFIG_SYS_IBAT2U #define CONFIG_SYS_DBAT3L CONFIG_SYS_IBAT3L #define CONFIG_SYS_DBAT3U CONFIG_SYS_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.
