[Travis]

What does it mean by Scatter mode and Gather mode in GPDMA?

Scatter - Relevant to destination transfers within a block. The destination address is
incremented or decremented by a programmed amount when a scatter boundary is
reached. The number of AHB transfers between successive scatter boundaries is
under software control.



Gather - Relevant to source transfers within a block. The source address is
incremented or decremented by a programmed amount when a gather boundary is
reached. The number of AHB transfers between successive gather boundaries is
under software control.
