From: Ellie Reeves <ellierevves@gmail.com>

This is the storage the machine boots from by default. The partitioning
is taken from the U-Boot that is shipped with the board. There is some
more space on the flash that isn't used.

From: Victor Gu <xigu@marvell.com>

The PSCI area should be reserved in Linux for PSCI operations such as
suspend/resume.

Reserve 2MiB of memory which matches the area used by ATF (BL1, BL2,
BL3x, see [1] in ATF source code). This covers all PSCI code and data
area and is 2MiB aligned, which is required by Linux for huge pages
handling.
