U-Boot for MOUSSE/MPC8240 (KAHLUA)----------------------------------James Dougherty (jfd@broadcom.com), 09/10/01The Broadcom/Vooha Mousse board is a 3U Compact PCI system boardwhich uses the MPC8240, a 64MB SDRAM SIMM, and has onboardDEC 21143, NS16550 UART, an SGS M48T59Y TOD, and 4MB FLASH.See also: http://www.vooha.com/* NVRAM setenv/printenv/savenv supported.* Date Command* Serial Console support* Network support* FLASH of kernel images is supported.* FLASH of U-Boot to onboard and PLCC boot region.* Kernel command line options from NVRAM is supported.* IP PNP options supported.U-Boot Loading...U-Boot 1.0.5 (Sep 10 2001 - 00:22:25)CPU:   MPC8240 Revision 1.1 at 198 MHz: 16 kB I-Cache 16 kB D-CacheBoard: MOUSSE MPC8240/KAHLUA - CHRP (MAP B)Built: Sep 10 2001 at 01:01:50MPLD:  Revision 127Local Bus:  33 MHzRTC:   M48T589 TOD/NVRAM (8176) bytes  Current date/time: 9/10/2001 0:18:52DRAM:  64 MBFLASH:  1.960 MBPCI:    scanning bus0 ...  bus dev fn venID devID class  rev MBAR0    MBAR1    IPIN ILINE  00  00  00 1057  0003  060000 11  00000008 00000000 01   00  00  0d  00 1011  0019  020000 41  80000001 80000000 01   01  00  0e  00 105a  4d38  018000 01  a0000001 a0001001 01   03In:    serialOut:   serialErr:   serialHit any key to stop autoboot:  0=>I.

U-Boot Image SupportThe U-Boot boot loader assumes that after you buildyour kernel (vmlinux), you will create a U-Boot imageusing the following commands or script:#!/bin/csh/bin/touch vmlinux.img/bin/rm vmlinux.imgset path=($TOOLBASE/bin $path)set path=($U_BOOT/tools $path)powerpc-linux-objcopy -S -O binary vmlinux vmlinux.bingzip -vf vmlinux.binmkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 -n vmlinux.bin.gz -d vmlinux.bin.gz vmlinux.imgls -l vmlinux.imgVI. ONBOARD FLASH SupportFLASH support is provided for the onboard FLASH chip Bootrom area.U-Boot is loaded into either the ROM boot region of the FLASH chip,after first being boot-strapped from a pre-progammed AMD29F040 PLCCbootrom. The PLCC needs to be programmed with a ROM burner usingAMD 29F040 ROM parts and the u-boot.bin or u-boot.hex (S-Record)images.The PLCC overlays this same region of flash as the onboard FLASH,the jumper J100 is a chip-select for which flash chip you want toprogam. When jumper J100 is connected to pins 2-3, you boot fromPLCC FLASH.To bringup a system, simply flash a flash an AMD29F040 PLCCbootrom, and put this in the PLCC socket. Move jumper J100 topins 2-3 and boot from the PLCC.Now, while the system is running, move Jumper J100 topins 1-2 and follow the procedure below to FLASH a bootrom(u-boot.bin) image into the onboard bootrom region (AMD29LV160DB):tftp 100000 u-boot.binprotect off FFF00000 FFF7FFFFerase FFF00000 FFF7FFFFcp.b 100000 FFF00000 \$(filesize)\Here is an example:=>tftp 100000 u-boot.bineth_halteth0: DC21143 Ethernet adapter(bus=0, device=13, func=0)DEC Ethernet iobase=0x80000000ARP broadcast 1Filename 'u-boot.bin'.Load address: 0x100000Loading: #########################doneBytes transferred = 123220 (1e154 hex)eth_halt=>protect off FFF00000 FFF7FFFFUn-Protected 8 sectors=>erase FFF00000 FFF7FFFFErase Flash from 0xfff00000 to 0xfff7ffffErase FLASH[PLCC_BOOT] -8 sectors:........ doneErased 8 sectors=>cp.b 100000 FFF00000 1e154Copy to Flash...
