Alexander, thank you for making a contribution.

Being able to reference a ROM filesystem via a FIS entry seems like a good idea
since this is a typical usage scenario and the feature would improve usability.
However, one could also argue that this is application-level glue and does not
belong in the ROM filesystem package.

Any comments from other maintainers?

If there is some consensus that the feature is desirable, the lookup should be
made conditional on a new CYGFUN_FS_ROM_FLASH_BLOCK_DEVICE_LOOKUP option which
"requires CYGPKG_IO_FLASH_BLOCK_DEVICE" to avoid forcing a dependency on
CYGPKG_IO_FLASH.

I agree with John. Yes it should be optional, and due to the requirement should
 default to off.

Alexander, could you wrap your changes in:

  #if defined(CYGFUN_FS_ROM_FLASH_BLOCK_DEVICE_LOOKUP)
  #endif

add the following CDL option to romfs.cdl:

  cdl_option CYGFUN_FS_ROM_FLASH_BLOCK_DEVICE_LOOKUP {
    display "Lookup flash block device names"
    flavor bool
    requires CYGPKG_IO_FLASH
    requires CYGPKG_IO_FLASH_BLOCK_DEVICE
    default_value 0
    description "Enables the location of a ROM filesystem to
      be specified using a flash block device name such as
      \"/dev/flash/fis/romfs\" in the call to mount()."
  }

and resubmit your patch please?

Updated patch with John's proposal

John, thanks for CDL code. I incorporated it in the patch and wrapped my code
with #ifdef's.
