From: "Edgar E. Iglesias" <edgar.igles...@xilinx.com> Hi,
This is a second round of AArch64 EL2/3 patches working on the exception model. Among other things adding HVC/SMC, interrupt routing to EL2/3 and Virtual IRQs/FIQs. The VIRQ/VFIQ support only adds the external signal delivery method. Patch 3 is a bug fix. Patch 14 fails checkpatch, seems like a bug in checkpatch, CC:d Blue. This conflicts slightly with the PSCI emulation patches that Rob posted. A rebase should be trivial, hooking in the PSCI emulation calls in the HVC/SMC helpers. Cheers, Edgar v1 -> v2: * Avoid imm16 mask in syndrome generation * Use g_assert_not_reached() in arm_excp_unmasked() * Avoid some logic duplication in arm_excp_target_el and arm_excp_unmasked. * Put arm_excp_target_el in helper.c to start with. * Fix SMC disable (SMD or SCD) for ARMv7 only applies if EL2 exists * SCR_RES0_MASK -> SCR_MASK * HCR_RES0_MASK -> HCR_MASK * Fix SMC routing to EL2, only applies for NS EL1. * Fix CPreg defs for ESR_EL2/3 * Fix SMC helper, SMC routing to EL2 and SCR.SMD for AArch32.
