2018-05-07arm: v7: Kconfig: Rename CPU_V7 as CPU_V7ALokesh Vutla
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

2018-05-07arm: stm32mp1: add PSCI supportPatrick Delaunay
Add PSCI v1.0 support for Linux and manage PSCI state for each CPU (affinity 0 level) with all mandatory functions: - PSCI_VERSION - CPU_SUSPEND - CPU_OFF - CPU_ON - AFFINITY_INFO - SYSTEM_OFF - SYSTEM_RESET - PSCI_FEATURES and 1 optional to avoid Linux warning - MIGRATE_INFO_TYPE Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: CITOOLS <smet-aci-reviews@lists.codex.cro.st.com>
2018-04-28arm: move SYS_ARCH_TIMER to KConfigAndre Przywara
SYS_ARCH_TIMER guards the usage of the ARM Generic Timer (aka arch timer) in U-Boot. At the moment it is mandatory for ARMv8 and used by a few ARMv7 boards. Add a proper Kconfig symbol to express this dependency properly, allowing certain board configuration to later disable arch timer in case there are any problems with it.

2018-04-06stm32mp: handle SYSRESETPatrick Delaunay

2018-04-06stm32mp1: select boot device and partitionPatrick Delaunay
Bootrom loads SPL from SDCARD or eMMC according BootPin selection. Then SPL loads U-Boot on the same mmc device with the following predefined GPT partitioning: on SDCARD: gpt partitioning 1: SPL 2: SPL#2 3: U-Boot 4: bootable partition on eMMC: The 2 boot partitions are used for SPL (2 copy) boot1: SPL boot2: SPL#2 The user partition use gpt partitioning 1: U-Boot 2: bootable partition This patch select the correct SPL partition (3 for SDCARD on mmc0 and 1 for eMMC on mmc1) according the BootRom information saved in TAMP register and based on configuration flasg: - CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION => for BOOT_DEVICE_MMC1 or mmc 0 in U-Boot - CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_MMC2 (new) => for BOOT_DEVICE_MMC2 or mmc 1 in U-Boot And the correct boot_targets is selected according the environment variables boot_device and boot_instance, with preboot command, to search the bootable partition with kernel on this device (generic distro support).
