Well, _making_ the image is easy. the mkimage tool will happily combine any files you pass to it into one multifile image (MFI).
I thought I've seen a command line option for "mkimage" saying something about scripts...
Sure. You can build a script image.
But your original question was how to "make an u-boot image that contains a kernel _and_ a script". That would be a MFI, and there is no script support for MFIs.
Than how should I understand the following lines from ppcboot/common/cmd_autoscript.c
You can run a script image. This is an image that contains ONLY the script.
Is this actually a multi step solution? First download the script, then download the binary data (e.g. kernel image) and then execute the script?
No. But you cannot combine a Linux kernel and a script in a single MFI (yet). Or actually you can, but you canot make any use of such an image ;-)
Normally the board boots from flash (in detail: pImage is stored on a JFFS2 partition, which serves as the root fs as well). But in the case that no (valid) pImage is found, I would like ppcboot (sorry, still using this) to automagically download a whole pFlashdisk image and burn that to the flash. So I thougth about using an MFI (containing the data and the update script) that gets downloaded...
Use the update script to download and install the kernel image, then.
