This one is more controversial:
- Does anyone need fbdev for boot-testing?
- This disables two drivers that cannot be modular (FB_WM8505 and
FB_SIMPLE), and the PLAT_VERSATILE_CLCD helper support.My guess is that FB_WM8505 would be useful, as the chip is primarily used in tablets that don't come with an easily accessible UART. OTOH, those machines are very rare, and we may decided that we just include them for build testing as well as the odd developers that do have a UART. Arnd
