There are many different formats in each header now, such as _ASM_XXX_H, __ASM_XXX_H, _ASM_RISCV_XXX_H, RISCV_XXX_H, etc., This patch tries to unify the format by using _ASM_RISCV_XXX_H, because the most header use it now. This patch also adds the conditional to the headers if they lost it. Signed-off-by: Zong Li <zong.li@sifive.com> Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>
