Add atos self test to perform atos for different sids. To enable, set CONFIG_ARM_SMMU_SELFTEST and arm_smmu.selftest=1 and set the sids and masks in arm_smmu.selftestsids in the below format smmu_name,no_of_sids,sid:mask. for eg: arm_smmu.selftestsids=kgsl,0x1,0x7:0x400,apps,0x2, 0x1:0x0,0x51f:0x0 Change-Id: I74134ed712e06a17b1570256e2ee3820df2f4457 Signed-off-by: Charan Teja Reddy <charante@codeaurora.org> Signed-off-by: Prakash Gupta <guptap@codeaurora.org> Signed-off-by: Vijayanand Jitta <vjitta@codeaurora.org>
