Add initial framebuffer debug tool
I've started with a basic debug tool that performs the FBIOGET_FSCREENINFO
and FBIOGET_VSCREENINFO
IOCTLs calls and print out all the values in the struct retrieved.
I've chose the name fbdebug
to follow the busybox naming for framebuffer tools (fbset
, fbsplash
,...)
Please review and test it, thanks.
