riscv: Add QEMU virt board support This adds QEMU RISC-V 'virt' board target support, with the hope of helping people easily test U-Boot on RISC-V. The QEMU virt machine models a generic RISC-V virtual machine with support for the VirtIO standard networking and block storage devices. It has CLINT, PLIC, 16550A UART devices in addition to VirtIO and it also uses device-tree to pass configuration information to guest software. It implements RISC-V privileged architecture spec v1.10. Both 32-bit and 64-bit builds are supported. Support is pretty much preliminary, only booting to U-Boot shell with the UART driver on a single core. Booting Linux is not supported yet.

global: Move remaining CONFIG_SYS_SDRAM_* to CFG_SYS_SDRAM_* The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace.

riscv: timer: Update the sifive clint timer driver to support aclint This RISC-V ACLINT specification [1] defines a set of memory mapped devices which provide inter-processor interrupts (IPI) and timer functionalities for each HART on a multi-HART RISC-V platform. The RISC-V ACLINT specification is defined to be backward compatible with the SiFive CLINT specification, however the device tree binding is a new one. This change updates the sifive clint timer driver to support ACLINT mtimer device, using a per-driver data field to hold the mtimer offset to the base address encoded in the mtimer node.
