Subject: [PULL 17/26] hw/sd: Introduce sd_cmd_handler type
Date: Fri, 1 Sep 2023 11:42:05 +0200 [thread overview]
Message-ID: <20230901094214.296918-18-clg@kaod.org> (raw)
In-Reply-To: <20230901094214.296918-1-clg@kaod.org>
From: Philippe Mathieu-Daudé <f4bug@amsat.org>
Add 2 command handler arrays in SDProto, for CMD and ACMD.
Have sd_normal_command() / sd_app_command() use these arrays:
if an command handler is registered, call it, otherwise fall
back to current code base.
