From 85bb4457ef47db81afef98f97de524199e139433 Mon Sep 17 00:00:00 2001 From: Santosh Yaraganavi <santoshsy@gmail.com> Date: Mon, 23 Apr 2012 18:52:11 +0530 Subject: [PATCH] [SCSI] ufs: Assign UTRLBAU = upper_32_ bits(UTRLD base address) UTP Transfer request list base registers UTRLBA and UTRLBAU must be assigned, lower-32 and upper-32 bits of UTRLD list physical base addresses respectively. Currently UTRLBAU is being assigned lower-32 bits of UTRLD physical base address. This will cause an issue with controllers that can support 64-bit addressing. This patch correctly assigns upper-32 bits of UTRLD physical base address to UTRLBAU.
