Subject: [U-Boot] [PATCH 02/11] ARM: at91: ma5d4: Switch DDR2 controller to sequencial address decoding
Date: Tue, 2 May 2017 20:27:41 +0200 [thread overview]
Message-ID: <20170502182750.8907-2-marex@denx.de> (raw)
In-Reply-To: <20170502182750.8907-1-marex@denx.de>
According to the datasheet, sequential mapping is used for DDR
SDRAM, while interleaved mapping is used for regular SDRAM.
Incorrect configuration of this bit does indeed cause sporadic
memory instability.
