This series adds RTC device to QEMU RISC-V virt machine. We have
selected Goldfish RTC device model for this. It's a pretty simple
synthetic device with few MMIO registers and no dependency external
clock. The driver for Goldfish RTC is already available in Linux so
we just need to enable it in Kconfig for RISCV and also update Linux
defconfigs.
We have tested this series with Linux-5.3 plus defconfig changes
available in 'goldfish_rtc_v1' branch of:
https://github.com/avpatel/linux.git
Changes since v1:
- Removed redundant object properties from Goldfish RTC emulation
- Added vmstate for Goldfish RTC
