2021-04-20Add SiP service to configure Arm Ethos-N NPUMikael Olsson
By default the Arm Ethos-N NPU will boot up in secure mode. In this mode the non-secure world cannot access the registers needed to use the NPU. To still allow the non-secure world to use the NPU, a SiP service has been added that can delegate non-secure access to the registers needed to use it. Only the HW_CONFIG for the Arm Juno platform has been updated to include the device tree for the NPU and the platform currently only loads the HW_CONFIG in AArch64 builds.

2020-09-29drivers: arm: gicv3: Allow detecting number of coresAndre Przywara
A GICv3 interrupt controller will be instantiated for a certain number of cores. This will result in the respective number of GICR frames. The last frame will have the "Last" bit set in its GICR_TYPER register. For platforms with a topology unknown at build time (the Arm FPGAs, for instance), we need to learn the number of used cores at runtime, to size the GICR region in the devicetree accordingly. Add a generic function that iterates over all GICR frames until it encounters one with the "Last" bit set. It returns the number of cores the GICv3 has been configured for.

2020-06-22TF-A GIC driver: Add barrier before eoiSandeep Tripathy
It is desired to have the peripheral writes completed to clear the interrupt condition and de-assert the interrupt request to GIC before EOI write. Failing which spurious interrupt will occurred. A barrier is needed to ensure peripheral register write transfers are complete before EOI is done. GICv2 memory mapped DEVICE nGnR(n)E writes are ordered from core point of view. However these writes may pass over different interconnects, bridges, buffers leaving some rare chances for the actual write to complete out of order. GICv3 ICC EOI system register writes have no ordering against nGnR(n)E memory writes as they are over different interfaces. Hence a dsb can ensure from core no writes are issued before the previous writes are *complete*.

2020-06-09GICv3: GIC-600: Detect GIC-600 at runtimeAndre Przywara
The only difference between GIC-500 and GIC-600 relevant to TF-A is the differing power management sequence. A certain GIC implementation is detectable at runtime, for instance by checking the IIDR register. Let's add that test before initiating the GIC-600 specific sequence, so the code can be used on both GIC-600 and GIC-500 chips alike, without deciding on a GIC chip at compile time. This means that the GIC-500 "driver" is now redundant. To allow minimal platform support, add a switch to disable GIC-600 support.

2020-01-03drivers: add a driver for snoop control unitVishnu Banavath
The SCU connects one to four Cortex-A5/Cortex-A9 processors to the memory system through the AXI interfaces. The SCU functions are to: - maintain data cache coherency between the Cortex-A5/Cortex-A9 processors - initiate L2 AXI memory accesses - arbitrate between Cortex-A5/Cortex-A9 processors requesting L2 accesses - manage ACP accesses. Snoop Control Unit will enable to snoop on other CPUs caches. This is very important when it comes to synchronizing data between CPUs. As an example, there is a high chance that data might be cache'd and other CPUs can't see the change. In such cases, if snoop control unit is enabled, data is synchoronized immediately between CPUs and the changes are visible to other CPUs. This driver provides functionality to enable SCU as well as enabling user to know the following - number of CPUs present - is a particular CPU operating in SMP mode or AMP mode - data cache size of a particular CPU - does SCU has ACP port - is L2CPRESENT Change-Id: I0d977970154fa60df57caf449200d471f02312a0 Signed-off-by: Vishnu Banavath <vishnu.banavath@arm.com>

2019-01-22ti: k3: common: Add support for runtime detection of GICR base addressAndrew F. Davis
Valid addresses for GICR base are always a set calculable distance from the GICD and is based on the number of cores a given instance of GICv3 IP can support. The formula for the number of address bits is given by the ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to one for GICR instances. Holes in the GIC address space are also guaranteed to safely return 0 on reads. This allows us to support runtime detection of the GICR base address by starting from GIC base address plus BIT(18) and walking until the GICR ID register (IIDR) is detected. We stop searching after BIT(20) to prevent searching out into space if something goes wrong. This can be extended out if we ever have a device with 16 or more cores. Signed-off-by: Andrew F. Davis <afd@ti.com>
2019-01-04Sanitise includes across codebaseAntonio Nino Diaz
Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.
