Marek Vasut a382725060 serial: Remove CONFIG_SERIAL_MULTI from serial drivers
Remove the support for not-CONFIG_SERIAL_MULTI part from serial
port drivers and some board files. Since CONFIG_SERIAL_MULTI is
now enabled by default, that part is a dead code. Remove it.

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

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

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)

			  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.
Supported features:

- NVRAM setenv/getenv (used by Linux Kernel for configuration variables)
- BCM570x TFTP file transfer support
- LCD Display Support
- DOC Support - (underway)
