2018-07-05hw/riscv/sifive_u: Connect the Cadence GEM Ethernet deviceAlistair Francis
Connect the Cadence GEM ethernet device. This also requires us to expose the plic interrupt lines. Signed-off-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Michael Clark <mjc@sifive.com>

2018-07-05hw/riscv/sifive_u: Set the interrupt controller number of interruptsAlistair Francis
Set the interrupt-controller ndev to the correct number taken from the HiFive Unleashed board. Signed-off-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Michael Clark <mjc@sifive.com>
2018-07-05hw/riscv/sifive_u: Set the soc device tree node as a simple-busAlistair Francis
To allow Linux to ennumerate devices on the /soc/ node set it as a "simple-bus". Signed-off-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Michael Clark <mjc@sifive.com>
2018-07-05hw/riscv/sifive_plic: Use gpios instead of irqsAlistair Francis
Instead of creating the interrupt in lines with qemu_allocate_irq() use qdev_init_gpio_in() as this gives us the ability to use the qdev*gpio*() helpers later on.

2018-07-05hw/riscv/sifive_u: Create a SiFive U SoC objectAlistair Francis
Create a SiFive Unleashed U54 SoC and use that in the sifive_u machine. We leave the SoC, RAM, device tree and reset/fdt loading as part of the machine. All the other device creation has been moved to the SoC. Signed-off-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Michael Clark <mjc@sifive.com>
2018-05-06RISC-V: Mark ROM read-only after copying in codeMichael Clark
The sifive_u machine already marks its ROM readonly however it has the wrong base address for its mask ROM. This patch fixes the sifive_u mask ROM base address. This commit makes all other boards consistently use mask_rom as the variable name for their ROMs. Boards that use device tree now check that that the device tree fits in the assigned ROM space using the new qemu_fdt_totalsize(void *fdt) interface, adding a bounds check and error message. This can detect truncation.

2018-05-06RISC-V: Remove unused class definitionsMichael Clark
Removes a whole lot of unnecessary boilerplate code. Machines don't need to be objects. The expansion of the SOC object model for the RISC-V machines will happen in the future as SiFive plans to add their FE310 and FU540 SOCs to QEMU. However, it seems that this present boilerplate is complete unnecessary.

2018-05-06RISC-V: Remove identity_translate from load_elfMichael Clark
When load_elf is called with NULL as an argument to the address translate callback, it does an identity translation. This commit removes the redundant identity_translate callback.
