Subject: [PATCH 0/2] dmaengine: hdmac: Add scatter-gathered memset support

Hi Vinod,

Here is a patch serie that adds support in the Atmel HDMAC for memset
over a discontiguous memory area.

Just like for the memset, it's used on those SoCs to support
framebuffer related operations that cannot be performed either by the
display engine or the (non-existent) GPU.

Let me know what you think,
Maxime
