[PATCH v1 2/6] riscv/sifive_u: Add QSPI memory region

2019-09-19 Thread Alistair Francis
There doesn't seem to be details on what QSPI the HiFive Unleashed uses. To allow boot firmware developers to use QEMU to target the Unleashed let's add a chunk of memory to represent the QSPI. This can be targeted using QEMU's -device loader command line option. Signed-off-by: Alistair Francis
