Hi, Liviu,

Thanks for the suggestion.

It seems like to me that the issue is the default address assumed by qemu,
which is 0x0.
(since Eclipse QEMU uses the same code, I believe they have the same
problem.)
But it's not always the case.
For example, zynqmp's ram base address is 0x80000000,
and I have to tweak that address in HEAPINFO handling code every time I
change to a new HW config.

Regards,
