From 1669b3d1a0b56178ec8123c48fbf6dabe46b23a4 Mon Sep 17 00:00:00 2001 From: Ovidiu Panait Date: Sun, 13 Feb 2022 10:09:20 +0200 Subject: [PATCH] microblaze: exception: migrate MICROBLAZE_V5 to Kconfig Also, rename it to XILINX_MICROBLAZE0_DELAY_SLOT_EXCEP, since it only covers delay slot exception support.
