[U-Boot-Users] bootm and script images

[Matthias Fuchs]

Hi,

I am wondering if there is a special reason why bootm currently cannot 
handle script images. Does anything speak against bootm calling 
autoscript() for AU_SCRIPT marked images?

Yes. Bootm is intended to boot (Linux)  kernel  images,  that's  all.
There  are  other  commands to deal with other objects, like "go" for
standalone images, "autoscr" for scripts,

Please keep the design smalland simple. We don't need no  eierlegende
Woll-Milch-S?ue in U-Boot :-)

Best regards,

Wolfgang,

this is what I need to do: we have u-boot running on a PCI adapter card.
The whatever-image is directly loaded into the card's RAM over the PCI 
bus. Then we trigger booting the image by modifying a magic RAM cell.

Currently only Linux kernel images and combined kernel + initrd images 
are supported. Now we want to allow using u-boot scripts with the same 
mechanism.

So if you think that a "universal" boot command would blow things up to 
much, I will think of a mofication of our loadpci BSP command. I will 
decide inside this command if bootm or autoscr must be used.

Yes, I know.

Well, it would be just one more case in the bootm switch statement.
