Using an "lcd" hierarchy for LCD segment displays would imply a separate
hierarchy for LED segment displays with similar controllers. I think a more
generic name is desirable.
Historically, support for simple devices with no corresponding I/O
infrastructure package has tended to be bundled with the relevant HAL package.
However, I do appreciate the desire for portability across architectures.
A few possibilities for consideration:
1) Introduce a hal/devs/ hierarchy for HAL-level device definitions which may
be required across multiple architectures. Accessed directly as if part of a
platform HAL or variant HAL package.
2) Introduce a devs/misc/ hierarchy for miscellaneous simple eCos devices with
no corresponding I/O layer. Accessed via eCos device lookup.
3) Create an I/O infrastructure package for segment displays.
