riscv: qemu: add SPL configuration

2019-08-26T08:07:42+00:00

Add two new configurations (qemu-riscv{32,64}_spl_defconfig) with SPL
enabled for RISC-V QEMU. QEMU does not require SPL to run U-Boot. The
configurations are meant to help the development of SPL on RISC-V.

The configurations enable RAM as the only SPL boot device. Images must
be loaded at address 0x80200000. In the default boot flow, U-Boot SPL
starts in machine mode, loads the OpenSBI FW_DYNAMIC firmware and U-Boot
proper from the supplied FIT image, and starts OpenSBI. U-Boot proper is
then started in supervisor mode by OpenSBI.

qemu-riscv: enable VIRTIO_PCI

2019-07-18T15:31:28+00:00

libvirt v.5.3.0 with QEMU 4.0.0 or above uses PCI automatically and
thus devices (network, storage, etc) are connected via PCI.

virtio based devices.

riscv: qemu: Use correct SYS_TEXT_BASE for S-mode on 32bit system

2019-05-09T08:46:24+00:00

For 32bit system, the OpenSBI (or BBL) will jump to 0x80400000 address
in S-mode whereas for 64bit system it will jump to 0x80200000 address
in S-mode.

Currently, the S-mode U-Boot sets SYS_TEXT_BASE to 0x80200000 for both
32bit and 64bit system. This breaks S-mode U-Boot for 32bit system.

This patch sets different SYS_TEXT_BASE for 32bit and 64bit system so
that S-mode U-Boot works fine for both.

riscv: Rename cpu/qemu to cpu/generic

2019-02-27T01:12:33+00:00

The QEMU CPU support under arch/riscv is pretty much generic
and works fine for SiFive Unleashed as well. In fact, there
will be quite a few RISC-V SOCs for which QEMU CPU support
will work fine.

This patch renames cpu/qemu to cpu/generic to indicate the
above fact. If there are SOC specific errata workarounds
required in cpu/generic then those can be done at runtime
in cpu/generic based on CPU vendor specific DT compatible
string.
