From f303aaf21b968ab959edcc354892f9eca8907e0b Mon Sep 17 00:00:00 2001 From: Patrice Chotard Date: Tue, 18 Jul 2017 17:37:27 +0200 Subject: ram: stm32: add second SDRAM bank management FMC is able to manage 2 SDRAM banks, but the current driver implementation is only able to manage the first SDRAM bank. Even if only bank2 is used, some bank1 registers must be configured.
