[PATCH] ARM: dts: stm32f429: Boost perfs by remapping SDRAM Bank 1 to 0x0

2015-12-02 Thread Maxime Coquelin
STM32F429 allows to remap FMC SDRAM Bank 1 from 0xc000 to 0x0, by writing 0x4 to SYSCFG_MEMRMP register. As mentionned in the reference manual (see chapter 9.3.1), the performance gain is really interresting: "In remap mode at address 0x , the CPU can access the external memory via
