Hi Prafulla,

I was simply trying to mirror what the vendor U-Boot was passing to the
vendor kernel flashed on the device. My theory was that by comparing the
boot logs of the vendor U-Boot and vendor kernel, with the boot logs of
custom U-Boot and vendor kernel, I could make sure that my custom U-Boot
was doing the right thing. Including this ATAG allowed my to obtain
identical kernel boot logs.

That said, I'm happy to leave this portion out if it is not acceptable.
Especially if mainline kernel doesn't recognise that ATAG anyway.

Regards,

Rogan
