From 9b1eb2365e0039021036e0507b978804edab0d71 Mon Sep 17 00:00:00 2001 From: Nemui Trinomius Date: Mon, 4 Nov 2013 15:43:43 +0900 Subject: [PATCH] fm3: fix Fujitsu MB9Ax family support Some MB9Ax (especially few internal SRAM model) fails programming because of wrong SRAM basic-address on running algorithm. Default SRAM basic-address must be 0x20000000. This patch is fixing default SRAM basic-address and ramcode offset. Tested on a MB9BF618T and MB9AF112K.
