Most important registers are those related to DRAM initialization and calibration, where SPL initiates process and waits until certain bit is set/cleared. This patch adds these registers, initializes reset values from user's guide and updates state of registers as SPL expects it.

Only master-mode functionality is implemented. The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is first part enabling the TWI/I2C bus operation. Since both Allwinner A10 and H3 use the same module, it is added for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.

That in turn means that tests of cpu_isar_feature(aa64_something, cpu) will return true. Until now we have had a design policy that you shouldn't check an aa64_ feature unless you know that the CPU has AArch64; but this is quite fragile as it's easy to forget and only causes a problem in the corner case where AArch64 was turned off. In particular, when we extend the ability to disable AArch64 from only KVM to also TCG there are many more aa64 feature check points which we would otherwise have to audit for whether they needed to be guarded with a check on ARM_FEATURE_AARCH64. Instead, make the CPU realize function zero out all the 64-bit ID registers if a TCG CPU doesn't have AArch64; this will make aa64_ feature tests generally return false. We only do this for TCG because only TCG really needs it, and for KVM it might be confusing to have QEMU's idea of the ID registers be different from KVM's.

The tolerance applies to a given cpreg kvm index, and can be of different types: a) mismatch in cpreg indexes - ToleranceNotOnBothEnds (cpreg index is allowed to be only present on one end) - ToleranceOnlySrcTestValue (cpreg index is allowed to be only present in source if its value @mask field matches @value) b) mismatch in cpreg values - ToleranceDiffInMask (value differences are allowed only within a mask) - ToleranceFieldLT (incoming field value must be less than a given value) - ToleranceFieldGT (incoming field value must be greater than a given value) A QLIST of such tolerances can be populated using a new helper: arm_register_cpreg_mig_tolerance() and arm_cpu_match_cpreg_mig_tolerance() allows to check whether a tolerance exists for a given kvm index and its criterion is matched. callers for those helpers will be introduced in subsequent patches. Only registration of migration tolerances related to cpreg index mismatch is currently allowed.

This has been fixed by commit + * 655659a74a36 ("target/arm: Correct encoding of Debug + * Communications Channel registers") by the introduction of correct + * separate cpreg definitions for AA64 and AA32 versions. However, + * the old cpreg definition couldn't be removed without breaking + * migration, so commit 4f2b82f604 reinstated the bogus encoding + * for migration data only. + * + * Now that we have migration tolerance infrastructure, we can use + * this to allow forward migration from the buggy QEMU versions, + * accepting and ignoring the bogus register if it is in the + * source data. QEMU 11.0 was the last version that sent the + * bogus encoding, so this workaround can be removed at the point + * where we no longer care about migration from that version + * (i.e. when we remove the "virt-11.0" machine type). + */ + arm_register_cpreg_mig_tolerance(cpu, dbgtr_el0_kvmidx, + 0, 0, ToleranceNotOnBothEnds); } else { define_arm_cp_regs(cpu, not_v7_cp_reginfo); } -- 2.43.0 From: Eric Auger <eric.auger@redhat.com> This reverts commit 4f2b82f60431 ("target/arm: Reinstate bogus AArch32 DBGDTRTX register for migration compat).
