Subject: [PATCH 7/8] iommu/arm-smmu: enlarge STRTAB_L1_SZ_SHIFT to support larger sidsize
Date: Fri, 26 Jun 2015 16:33:03 +0800 [thread overview]
Message-ID: <1435307584-9812-8-git-send-email-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <1435307584-9812-1-git-send-email-thunder.leizhen-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
Because we will choose the minimum value between STRTAB_L1_SZ_SHIFT and
IDR1.SIDSIZE, so enlarge STRTAB_L1_SZ_SHIFT will not impact the platforms
whose IDR1.SIDSIZE is smaller than old STRTAB_L1_SZ_SHIFT value.
