The Broadcom SBA RAID is a stream-based device which provides
RAID5/6 offload.

It requires a SoC specific ring manager (such as Broadcom FlexRM
ring manager) to provide ring-based programming interface. Due to
this, the Broadcom SBA RAID driver (mailbox client) implements
DMA device having one DMA channel using a set of mailbox channels
provided by Broadcom SoC specific ring manager driver (mailbox
controller).

The Broadcom SBA RAID hardware requires PQ disk position instead
of PQ disk coefficient. To address this, we have added raid_gflog
table which will help driver to convert PQ disk coefficient to PQ
disk position.

This patchset is based on Linux-4.11-rc1 and depends on patchset
"[PATCH v5 0/2] Broadcom FlexRM ring manager support"

Okay I applied and was about to push when I noticed this :(

So what is the status of this..?

PATCH2 is Acked but PATCH1 is under-review. Currently, its
v6 of that patchset.

The only dependency on that patchset is the changes in
brcm-message.h which are required by this BCM-SBA-RAID
driver.

@Jassi,
Can you please have a look at PATCH v6?

And I would need an immutable branch/tag once merged. I am going to keep
this series pending till then.

The Broadcom FlexRM patchset is pickedup by Jassi and
can be found in mailbox-for-next branch of
git://git.linaro.org/landing-teams/working/fujitsu/integration

Both patchset (Broadcom FlexRM patchset and this one) are
also available in sba-raid-v7 branch of
https://github.com/Broadcom/arm64-linux.git

Regards,
Anup
