Alistair Francis a6902ef0e3 riscv/sifive_u: Add L2-LIM cache memory ... On reset only a single L2 cache way is enabled, the others are exposed as memory that can be used by early boot firmware. This L2 region is generally disabled using the WayEnable register at a later stage in the boot process. To allow firmware to target QEMU and the HiFive Unleashed let's add the L2 LIM (LooselyIntegrated Memory). Ideally we would want to adjust the size of this chunk of memory as the L2 Cache Controller WayEnable register is incremented. Unfortunately I don't see a nice way to handle reducing or blocking out the L2 LIM while still allowing it be re returned to all enabled from a reset.
