Subject: [PATCHv8 13/30] x86: Adjust types used in port I/O helpers
Date: Wed, 6 Apr 2022 02:29:22 +0300 [thread overview]
Message-ID: <20220405232939.73860-14-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <20220405232939.73860-1-kirill.shutemov@linux.intel.com>
Change port I/O helpers to use u8/u16/u32 instead of unsigned
char/short/int for values. Use u16 instead of int for port number.
It aligns the helpers with implementation in boot stub in preparation
for consolidation.
