+Memory layout
+-------------
+
+A64, H5 and H6 SoCs
+~~~~~~~~~~~~~~~~~~~
+
+BL31 lives in SRAM A2, which is documented to be accessible from secure
+world only. Since this SRAM region is very limited (48 KB), we take
+several measures to reduce memory consumption. One of them is to confine
+BL31 to only 28 bits of virtual address space, which reduces the number
+of required page tables (each occupying 4KB of memory).
+The mapping we use on those SoCs is as follows:
+
+::
+
+ 0 64K 16M 1GB 1G+160M physical address
+ +-+------+-+---+------+--...---+-------+----+------+----------
+ |B| |S|///| |//...///| |////| |
+ |R| SRAM |C|///| dev |//...///| (sec) |////| BL33 | DRAM ...
+ |O| |P|///| MMIO |//...///| DRAM |////| |
+ |M| | |///| |//...///| (32M) |////| |
+ +-+------+-+---+------+--...---+-------+----+------+----------
+ | | | | | | / / / /
+ | | | | | | / / / /
+ | | | | | | / / / /
+ | | | | | | / // /
+ | | | | | | / / /
+ +-+------+-+---+------+--+-------+------+
+ |B| |S|///| |//| | |
+ |R| SRAM |C|///| dev |//| sec | BL33 |
+ |O| |P|///| MMIO |//| DRAM | |
+ |M| | |///| |//| | |
+ +-+------+-+---+------+--+-------+------+
+ 0 64K 16M 160M 192M 256M virtual address
+
+
+H616 SoC
+~~~~~~~~
+
+The H616 lacks the secure SRAM region present on the other SoCs, also
+lacks the "ARISC" management processor (SCP) we use. BL31 thus needs to
+run from DRAM, which prevents our compressed virtual memory map described
+above. Since running in DRAM also lifts the restriction of the limited
+SRAM size, we use the normal 1:1 mapping with 32 bits worth of virtual
+address space. So the virtual addresses used in BL31 match the physical
+addresses as presented above.
