From b0bc8b70ff74501fd7a6e42013a4a7ea05cf6ade Mon Sep 17 00:00:00 2001 From: Wolfgang Wegner Date: Fri, 23 Apr 2010 11:08:05 +0200 Subject: [PATCH] add Xilinx_abort_fn to Xilinx_Spartan3_Slave_Serial_fns Currently the hardware was left in an undefined state in case Spartan3 serial load failed. This patch adds Xilinx_abort_fn to give the board a possibility to clean up in this case.
