[U-Boot] [PATCH 1/2] board/bsc9132qds: Add DSP side tlb and laws
BSC9132QDS is a Freescale Reference Design Board for BSC9132 SoC which is a integrated device that contains two powerpc e500v2 cores and two DSP starcores.
To support DSP starcore -Creating LAW and TLB for DSP-CCSR space. -Creating LAW for DSP-core subsystem M2 and M3 memory -Creating LAW for 1GB DDR which is connected exclusively to DSP-cores

Email-id is no longer valid as person has left the company. Git send-email was throwing error as it could not send message to that mail.

Without an e-mail address, I suspect we cannot consider that person's Signed-off-by to be valid, if only because it does not identify a single individual any more.

Yes that's rite! alternatively you can just mention his name in the commit message(with _NO_ signed-of).

Note however that we *do* need a signed-off-by line.

We would still have Priyanka's signed-off-by.

You can use --suppress-cc=sob to tell git send-email to not automatically CC people with sign-off lines.
Or, you could use an ordinary e-mail client to send it, as long as it doesn't mangle the patch (mutt works well for this).
