I realized we forgot the documentation, so I'm going to squash this change in to patch 3: --- a/docs/system/arm/virt.rst +++ b/docs/system/arm/virt.rst @@ -43,6 +43,8 @@ The virt board supports: - Secure-World-only devices if the CPU has TrustZone: - A second PL011 UART + - A second PL061 GPIO controller, with GPIO lines for triggering + a system reset or system poweroff - A secure flash memory - 16MB of secure RAM -- PMM
v9: - cosmetic changes (move if from patch2 to patch3, rename function name and define). v8: - use gpio 0 and 1, align dtb with kernel gpio-restart, gpio-poweroff, change define names, trigger on upper front. (Peter Maydell). v7: - same as v6, but resplit patches: patch 2 no function changes and refactor gpio setup for virt platfrom and patch 3 adds secure gpio. v6: - 64k align gpio memory region (Andrew Jones) - adjusted memory region to map this address in the corresponding atf patch v5: - removed vms flag, added fdt (Andrew Jones) - added patch3 to combine secure and non secure pl061. It has to be more easy to review if this changes are in the separate patch. v4: rework patches accodring to Peter Maydells comments: - split patches on gpio-pwr driver and arm-virt integration. - start secure gpio only from virt-6.0. - rework qemu interface for gpio-pwr to use 2 named gpio. - put secure gpio to secure name space. v3: added missed include qemu/log.h for qemu_log(.. v2: replace printf with qemu_log (Philippe Mathieu-Daudé) This patch works together with ATF patch: https://github.com/muvarov/arm-trusted-firmware/commit/886965bddb0624bdf85103efb2b39fd4eb73d89b Maxim Uvarov (3): hw: gpio: implement gpio-pwr driver for qemu reset/poweroff arm-virt: refactor gpios creation arm-virt: add secure pl061 for reset/power down hw/arm/Kconfig | 1 + hw/arm/virt.c | 111 ++++++++++++++++++++++++++++++++++-------- hw/gpio/Kconfig | 3 ++ hw/gpio/gpio_pwr.c | 70 ++++++++++++++++++++++++++ hw/gpio/meson.build | 1 + include/hw/arm/virt.h | 2 + 6 files changed, 167 insertions(+), 21 deletions(-) create mode 100644 hw/gpio/gpio_pwr.c -- 2.17.1
