Link and Links again

Eric,

include the up stream bus. The up stream bus is the device.bus field.
So for 'normal' PCI bridges, with one up stream and one down stream
buses, its device.links = 1. Am I correct ?

Hello, 
I've got my linuxbios run to the point it tries to load the image from
an IDE drive. I use FILO as the payload.

1. What do I have to add in the Config.lb file to make it use filo? I
know CONFIG_FS_STREAM should be set to true. What else?

2. I remembered linuxbios supports ROM image size larger than 64K now.
But when got compiler errors when specifies it as 128K. Do I miss
anything?

Actually, don't set CONFIG_FS_STREAM if you're using Filo as a payload. 
Use the CONFIG_IDE_STREAM instead.

Here is my filo-using config

# Sample config file for the Arima HDAMA

target hdama.filo
mainboard arima/hdama
option DEFAULT_CONSOLE_LOGLEVEL=5
option MAXIMUM_CONSOLE_LOGLEVEL=5

romimage "normal"
    option USE_FALLBACK_IMAGE=0
    option ROM_IMAGE_SIZE=0x10000
    option LINUXBIOS_EXTRA_VERSION=".0Normal"
    payload /opt/filo/normal/filo.elf
end

romimage "fallback" 
    option USE_FALLBACK_IMAGE=1
    option ROM_IMAGE_SIZE=0x10000
    option LINUXBIOS_EXTRA_VERSION=".0Fallback"
    payload /opt/filo/fallback/filo.elf
end

buildrom ./linuxbios.rom ROM_SIZE "normal" "fallback"

Thanks for the file. But would it work if I specify the ROM_IMAGE_SIZE
larger than 0x10000?

ROM_IMAGE_SIZE

[Gin]

Not sure why this is happening. When I specify the ROM_IMAGE_SIZE to be
larger than 64k. The file linuxbios.strip is larger than linuxbios,
which is the file before the objcopy. This doesn't happen to the
rom_image_size that is 64k.
Here is the file size info.

good question.

I just found this out: there is a bug in the new build that has crept in.

If I build linuxbios from this file, and flash a 512KB flash, it won't 
boot.

If I do this:
cat linuxbios.rom linuxbios.rom > 1M
flash_rom 1M

to a 1M part, to boots fine.

I'm tracking it down.

Correct it only includes the device itself.
device.link.dev == device

Correct.

Yes.
