From 82604bd738ce34f37a1e0c679930ae27fa10ffc0 Mon Sep 17 00:00:00 2001 From: Thomas Heijligen Date: Sat, 19 Feb 2022 22:31:32 +0100 Subject: hwaccess: add endianness converting deserialization functions Add functions like `uint32_t read_le32(const void *base, size_t offset);` Read a 32 bit unsigned from a base with an offset. Having prototypes and a macro generated implementation makes it easier to read, understand and spot errors in one of them.
