Subject: [PATCH 6/7] bootconfig: Replace u16 and u32 with uint16_t and uint32_t
Date: Fri, 17 Sep 2021 19:03:08 +0900	[thread overview]
Message-ID: <163187298835.2366983.9838262576854319669.stgit@devnote2> (raw)
In-Reply-To: <163187294400.2366983.7393164788107844569.stgit@devnote2>

Replace u16 and u32 with uint16_t and uint32_t so
that the tools/bootconfig only needs <stdint.h>.

Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org>
