config FB_B2R2

help
B2R2 engine does various bit-blitting operations,post-processor operations
and various compositions.

default n
help
Configures how B2R2 access the memory bus. Enabling this will increase
the performance of B2R2 at the cost of using the bus more heavily.
If this is set to 'n', the hardware defaults will be used.
