+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  |////|      |

+   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.
