The virtual offset memory model used for i386-pcbios and x86_64-pcbios can be generalised to also cover riscv32-sbi and riscv64-sbi. In both architectures, the 32-bit builds will use a circular map of the 32-bit address space, and the 64-bit builds will use an identity map for the relevant portion of the physical address space, with iPXE itself placed in the negative (kernel) address space. Generalise and document the virt_offset mechanism, and set it as the default for both PCBIOS and SBI platforms. Signed-off-by: Michael Brown <mcb30@ipxe.org>
