hw/arm/allwinner-a10: Add the 'A' SRAM and the SRAM controller
From the "A10 User Manual V1.20" p.29: "3.2. Memory Mapping" and:
7. System Control
7.1. Overview
A10 embeds a high-speed SRAM which has been split into five segments.
See detailed memory mapping in following table:
Area Address Size (Bytes)
A1 0x00000000-0x00003FFF 16K
A2 0x00004000-0x00007FFF 16K
A3 0x00008000-0x0000B3FF 13K
A4 0x0000B400-0x0000BFFF 3K
Since for emulation purpose we don't need the segmentations, we simply define
the 'A' area as a single 48KB SRAM.
We don't implement the following others areas:
- 'B': 'Secure RAM' (64K),
- 'C': Debug/ISP SRAM
- 'D': USB SRAM
