From be9a9fc5e6dbc2775a490b79906b91e584b0b091 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 1 Aug 2015 20:39:46 +0200 Subject: [PATCH] ddr: altera: sdram: Clean up sdram_mmr_init_full() part 1 Zap all the ad-hoc readbacks from the registers and other useless and broken debug output. This is really not useful and is only confusing.
