So, we can always use include/asm-generic/bitsperlong.h, which determines BITS_PER_LONG depending on CONFIG_64BIT. This is what Linux does (at least in the kernel-space), and barebox can follow it. Currently, barebox only supports 32-bit riscv, but this should work when it supports 64-bit by adding CONFIG_64BIT to arch/riscv/Kconfig.
