My progress on real RISC-V hardware

After fixing Sifive UART driver I found that program stops at setting MMU page table. The same code is working fine on QEMU (I made setting SATP register earlier and added additional identity mappings so UART is accessible at physical address).

Testing is currently quite annoying. I need to shutdown development PC, unplug power cable from it, plug it to RISC-V and turn it on. When I want to change code, I need to plug power cable back to development PC. Power supply is ordered at 2021.07.01 at Amazon, but still not delivered. Amazon says that it should come until Friday (2021.07.09).
