The file I need to read is a firmware image for a network device that cannot be attached until the firmware is loaded. I would like to use something like splash_bmp to load a config file that specifys a vendor ID/cookie, an image type, offset, and filename. The driver would parse this config file and would load the appropriate firmware image for each card it detects. Due to licensing issues, firmware licensed for use with a particular vendor card may not be used with cards from a different vendor, though there is no technical reason why the same image can be used (that I know of so far.) Obviously, I could pre-load all the firmware images available but this seems wasteful. In addition, I would like the ability to upgrade the firmware on a card without bringing down the system. While I might make a device node to pipe the firmware image to the card once the system is up, giving the driver the ability to request and load the firmware image on demand would be nicer. -- | Matthew N.
