I think one isn't needed, since the config file must already have CONFIG_LCD_DT_SIMPLEFB enabled, since the existing code is under that ifdef. Acked-by: Stephen Warren <swarren@wwwdotorg.org>

Hmm... I'm a little torn, but in the long term I think it's better to keep subsystem-specific fdt code in separate files, because otherwise fdtdec.c will eventually grow to enormous proportions. > >> --- >> board/raspberrypi/rpi/rpi.c | 1 + >> common/Makefile | 1 + >> common/lcd.c | 50 -------------------------------------- >> common/lcd_simplefb.c | 59 +++++++++++++++++++++++++++++++++++++++++++++ >> include/fdt_simplefb.h | 14 +++++++++++ >> include/lcd.h | 3 --- >> 6 files changed, 75 insertions(+), 53 deletions(-) >> create mode 100644 common/lcd_simplefb.c >> create mode 100644 include/fdt_simplefb.h

I think one isn't needed, since the config file must already have CONFIG_LCD_DT_SIMPLEFB enabled, since the existing code is under that ifdef. Yes that was a poor choice of words on my part. Should have been something like "...is updated to accommodate the changes". I'll fix it in a V2. > > Acked-by: Stephen Warren <swarren@wwwdotorg.org> >

We now have api functions that can support compiling simplefb code as its own module. Since this code is not part of the display functionality, extract it to its own file. Raspberry Pi config file is updated to compile the new file.
