Subject: [PATCH] [SCSI] ufs: Assign UTRLBAU = upper_32_ bits(UTRLD base address)
Date: Mon, 23 Apr 2012 18:52:11 +0530 [thread overview]
Message-ID: <1335187331-2672-1-git-send-email-santoshsy@gmail.com> (raw)
From: Santosh Yaraganavi <santoshsy@gmail.com>
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.
