The only place we really need to know the minimum is within page-vary-target.c. Rename the target/arm TARGET_PAGE_BITS_MIN to TARGET_PAGE_BITS_LEGACY to emphasize what it really means. Move the assertions related to minimum page size as well. Reviewed-by: Pierrick Bouvier <pierrick.bouvier@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
