* ARM: mach-shmobile: Don't init CNTVOFF/counter if PSCI is availableOleksandr Tyshchenko2019-05-311-0/+17
| | | | | | | | | | | | | | | | | | | | If PSCI is available then most likely we are running on PSCI-enabled U-Boot which, we assume, has already taken care of resetting CNTVOFF and updating counter module before switching to non-secure mode and we don't need to. As the psci_smp_available() helper always returns false if CONFIG_SMP is disabled, it can't be used safely as an indicator of PSCI usage. For that reason, we check for the mandatory PSCI operation to be available. Please note, an extra check to prevent secure_cntvoff_init() from being called for secondary CPUs in headsmp-apmu.S is not needed, as SMP code for APMU based system is not executed if PSCI is in use.

* ARM: shmobile: rcar-gen2: Make sure CNTVOFF is initialized on CA7/15Geert Uytterhoeven2017-09-181-18/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Cortex-A7, the arch timer CNTVOFF register is uninitialized. Ideally it should be initialized by the boot loader, but it isn't. For the boot CPU, CNTVOFF is initialized by Linux since commit 9ce3fa6816c2fb59 ("ARM: shmobile: rcar-gen2: Add CA7 arch_timer initialization for r8a7794"). For secondary CPU cores, no such initialization is done. Hence when enabling SMP on r8a7794, the kernel log is spammed with: WARNING: Underflow in clocksource 'arch_sys_counter' observed, time update ignored. Please report this, consider using a different clocksource, if possible. Your kernel is probably still fine. As Marc Zyngier pointed out that Cortex-A15 and Cortex-A7 are similar with respect to CNTVOFF, we have been very lucky this just worked on R-Car Gen2 SoCs with Cortex-A15 cores. To fix this: - Move the existing inline asm code to initialize CNTVOFF to an assembler source file (adding comments and replacing hardcoded constants by definitions in the process), so it can be reused, - Perform the initialization of CNTVOFF on the boot CPU (Cortex-A15 or Cortex-A7) on all R-Car Gen2 and RZ/G1 parts, - Wrap the standard secondary_startup() routine inside a routine which initializes CNTVOFF. Based on patches by Hisashi Nakamura in the BSP.

| | | | | | | | | | | | | | | | | | | When using the new CPG/MSSR bindings, there is no longer a "renesas,rcar-gen2-cpg-clocks" node, and the code to obtain the external clock crystal frequency falls back to a default of 20 MHz. While this is correct for all upstream R-Car Gen2 and RZ/G1 boards, this is not necessarily the case for out-of-tree third party boards. Add support for finding the external clock crystal oscillator on RZ/G1M, and on R-Car H2, M2-W, and M2-N using the new CPG/MSSR bindings, through the corresponding "renesas,r8a77xx-cpg-mssr" nodes. Note that this is not needed on R-Car V2H and E2, and on RZ/G1E, as on those SoCs the arch_timer and generic counter clock is derived from the ZS clock instead.

The IRQ numbers of the GIC are now virtual, and no longer match the hardcoded hardware IRQ numbers in the legacy platform board code. To fix this issue specific to non-multiplatform r8a7790 and Lager: 1) Instantiate the GIC from platform board code and also 2) Skip over the DT arch timer as well as 3) Force delay setup based on DT CPU frequency With these 3 fixes in place interrupts on Lager are now unbroken.
