QMSS(Queue Manager Sub System) uses PDSPs to implement various
QM related functions like packet accumulation, QoS or event
management.

Patch adds firmware blob for the QMSS accumulator
functionality.

I know we are not adding firmware to kernel and the idea is to get them
loaded via rootfs. But this firmware is for an infrastructure component
which is needed for Keystone. The respective drivers got into the queue
and the firmware was dropped from the series to follow the firmware tree.
relevant discussion is here.
	http://www.spinics.net/lists/arm-kernel/msg364985.html

I would like to get this merged for 3.18 if firmware folks don't
have objection to it.

What does "infrastructure component" mean?

What is "Keystone"?

Did you submit this to the linux-firmware tree?

Did the driver that needs this get merged into Linus's tree yet?

thanks,

Common SOC components which are used by various subsystems like Networking,
SRIO, Crypto engines etc.

Keystone is ARM based SOC architectures with bunch of SOC peripherals.

./scripts/get_maintainer.pl didn't give me other list. Which list am
suppose to submit it to get it to linux-firmware.

Its queued now for 3.18.
