Subject: [U-Boot] [PATCH 06/10] make ide_led() a weak alias
Date: Sun, 7 Oct 2012 17:56:10 +0200 [thread overview]
Message-ID: <1349625374-12391-7-git-send-email-morpheus.ibis@gmail.com> (raw)
In-Reply-To: <1349625374-12391-1-git-send-email-morpheus.ibis@gmail.com>
Make ide_led() a weak alias instead of global/local function/empty macro
based on CONFIG_IDE_LED value and/or board-specific CONFIGs, to get rid of
board-specific code in cmd_ide.c
Define dummy values to get rid of compoler errors in case where ide_led()
used to be an empty macro
