CONFIG_SIM_FBBPP - Pixel depth in bits
NOTES:
- If CONFIG_SIM_X11FB is selected then CONFIG_SIM_FBBPP must
match the resolution of the display.
- If CONFIG_SIM_X11FB is selected then the following are
needed
CONFIG_SIM_FBBPP (must match the resolution of the display).
CONFIG_FB_CMAP=y
My system has 24-bit color, but packed into 32-bit words so
the correct seeting of CONFIG_SIM_FBBPP is 32.
- For whatever value of CONFIG_SIM_FBBPP is selected, then
the corresponing CONFIG_NXGLIB_DISABLE_*BPP setting must
the corresponidng CONFIG_NXGLIB_DISABLE_*BPP setting must
not be disabled.
- The default in defconfig is to use a generic memory buffer
for the framebuffer. defconfig-x11 is an example with X11
