+ Reserve memory from the top, tracked by gd->arch.resv_ram. This
+ reserved RAM can be used by special driver that resides in memory
+ after U-Boot exits. It's up to implementation to allocate and allow
+ access to this reserved memory. For example, the reserved RAM can
+ be at the high end of physical memory. The reserve RAM may be
+ excluded from memory bank(s) passed to OS, or marked as reserved.
