Trusted Applications use popular approach to determine required size
of buffer: client provides a memory reference with the NULL pointer to
a buffer. This is so called "Null memory reference". TA updates the

Qemu supports only 4 emulated IDE disks, when given more (or with higher
indexes), it will fail to start. Since the disks can still be accessible
using PV interface, just ignore emulated path and log a warning, instead
of rejecting the configuration altogether.
