Would it make sense to have drivers added to libchip for commonly used
Where can we find a real driver for a real device ? I feel we need real
drivers as examples in RTEMS.
I do not like the "application" needing to handle this. I think BSPs
should provide drivers and not applications. The device is specific to a
board and it is the role of the BSP to handle this sort of thing. If I
use a BSP that has suitable flash devices I would expect the BSP to
contain the support. It may be the application that enables and
configures the support given a correctly working and mapped set of
drivers from the BSP.
I regretted not providing a real driver interface to the flash memory in
the flashdisk block device. Having a real device interface means it can
be opened and managed without the file system, for example erasing or
testing the devices.

Found it. Thanks.
Do any of the files that contain the reference to the LICENSE file get
