This year, Amlogic updated the ARM Trusted Firmware reserved memory mapping
for Meson GXL SoCs and products sold since May 2017 uses this alternate
reserved memory mapping.
But products had been sold using the previous mapping.

This issue has been explained in [1] and a dynamic solution is yet to be
found to avoid loosing another 3Mbytes of reservable memory.

In the meantime, this patch adds this alternate memory zone only for
the GXL and GXM SoCs since GXBB based new products stopped earlier.

Thanks. Without this patch, memtest dies early on at physical address
0x05100000 due to an SError. With the patch, things work well, so:

Acked-by: Will Deacon <will.deacon@arm.com>
Tested-by: Will Deacon <will.deacon@arm.com>

Please also CC stable, because random SErrors under load aren't much fun ;)

Cheers,

I missed the Fixes tag on this one, but it's now commit 4ee8e51b9edf upstream.

Please apply to stable v4.10+
