Constant aw_fel::soc::AR100_ABUSING_SRAM_SWAP_BUFFERS

const AR100_ABUSING_SRAM_SWAP_BUFFERS: [SRAMSwapBuffers; 2]

AR100 SRAM swap buffers.

Use the SRAM section at 0x44000 as the backup storage. This is the memory, which is normally shared with the OpenRISC core (should we do an extra check to ensure that this core is powered off and can't interfere?).
