Subject: [U-Boot-Users] [PATCH] Add pre and post configuration callbacks for Spartan FPGAs
Date: Mon, 12 Nov 2007 18:18:58 +0100 [thread overview]
Message-ID: <11948879423127-git-send-email-matthias.fuchs@esd-electronics.com> (raw)
In-Reply-To: <1194887941159-git-send-email-matthias.fuchs@esd-electronics.com>
This patch adds a post configuration callback for Spartan2/3 FPGAs.
pre and post configuration callback are now optional and
not called when the function pointer is set to NULL.
