From f97aafdfafb13d146cdcac31dca49d30b8b58edd Mon Sep 17 00:00:00 2001 From: Andrey Yurovsky Date: Fri, 1 Nov 2013 14:29:17 -0700 Subject: [PATCH] stm32l flash: add another device ID Add device ID 0x437, a dual-bank part with 512KB total. This one used the Medium+/HD flash size register to read the flash size in Kb rather than the 0/1 code in the Medium+ parts.
