U-Boot for MOUSSE/MPC8240 (KAHLUA)
----------------------------------
James Dougherty (jfd@broadcom.com), 09/10/01
The Broadcom/Vooha Mousse board is a 3U Compact PCI system board
which uses the MPC8240, a 64MB SDRAM SIMM, and has onboard
DEC 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.

use the command:
setenv <attribute> <value>
type "saveenv" to write to NVRAM.
II. To boot from a hard drive:
setenv root /dev/hda1
III. IP options which configure the network:
ipaddr=<IP ADDRESS OF MACHINE>
netmask=<NETMASK>
hostname=mousse
ethaddr=00:00:10:20:30:44

IV. IP Options which configure NFS Root/Boot Support
root=/dev/nfs
serverip=<NFS SERVER IP ADDRESS>
nfsroot=<NFS SERVER IP ADDRESS>:/boot/root-fs
V. U-Boot Image Support
The U-Boot boot loader assumes that after you build
your kernel (vmlinux), you will create a U-Boot image
using the following commands or script:
#!/bin/csh
/bin/touch vmlinux.img
/bin/rm vmlinux.img
set path=($TOOLBASE/bin $path)
set path=($U_BOOT/tools $path)
powerpc-linux-objcopy -S -O binary vmlinux vmlinux.bin
gzip -vf vmlinux.bin
mkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 -n vmlinux.bin.gz -d vmlinux.bin.gz vmlinux.img
ls -l vmlinux.img
VI. ONBOARD FLASH Support
FLASH 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 PLCC
bootrom. The PLCC needs to be programmed with a ROM burner using
AMD 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 to
progam. When jumper J100 is connected to pins 2-3, you boot from
PLCC FLASH.
To bringup a system, simply flash a flash an AMD29F040 PLCC
bootrom, and put this in the PLCC socket. Move jumper J100 to
pins 2-3 and boot from the PLCC.
Now, while the system is running, move Jumper J100 to
pins 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.bin
protect off FFF00000 FFF7FFFF
erase FFF00000 FFF7FFFF
cp.b 100000 FFF00000 \${filesize}\
Here is an example:
=>tftp 100000 u-boot.bin
eth_halt
eth0: DC21143 Ethernet adapter(bus=0, device=13, func=0)
DEC Ethernet iobase=0x80000000

=>
B. FLASH RAMDISK REGION
FLASH support is provided for an Onboard 512K RAMDISK region.
TThe following commands will FLASH a bootrom (u-boot.bin) image
into the onboard FLASH region (AMD29LV160DB 2MB FLASH):
tftp 100000 u-boot.bin
protect off FFF80000 FFFFFFFF
erase FFF80000 FFFFFFFF
cp.b 100000 FFF80000 \${filesize}\
C. FLASH KERNEL REGION (960KB)
FLASH support is provided for the 960KB onboard FLASH1 segment.
This allows flashing of kernel images which U-Boot can load
and run (standalone) from the onboard FLASH chip. It also assumes
The following commands will FLASH a kernel image to 0xffe10000
tftp 100000 vmlinux.img
protect off FFE10000 FFEFFFFF
erase FFE10000 FFEFFFFF
cp.b 100000 FFE10000 \${filesize}\

When finished, use the command:
bootm ffe10000
to start the kernel.
Finally, to make this the default boot command, use
the following commands:
setenv bootcmd bootm ffe10000
savenv
to make it automatically boot the kernel from FLASH.
To go back to development mode (NFS boot)
setenv bootcmd tftp 100000 vmlinux.img\;bootm
