Then please let me know how this can be accomplished. The CPCI750 uses the same U-Boot image both for the video-enabled CPCI-host version and for the video-disabled CPCI-adapter version. The video driver is not called from within the CPCI750 board files. It's called from drivers/video/cfb_console.c.
And who calls the code in drivers/video/cfb_console.c ? I think this is the drv_video_init() call in common/devices.c, right?
Yes.
If this should be the highest level in the call chain, then any conditional calling should be done here.
OK, I can move the conditional calling to this level.
But - don't we already have a board_video_init() which could return proper status to abort initialization?
This is only implemented for some video drivers (SM501, SED13806, MB826xx) to return the base address for the graphics chip. The PCI drivers like the ct6900 don't use this interface. Here we have other means to get the base address.
I'll move the conditional calling to the highest level and resubmit.
Thanks.
