2017-09-15imx8qm/imx8qxp: enable standby suspendAnson Huang
As suspend with last CPU power down needs SCFW support, and it is NOT ready now, in order to enable kernel suspend function earlier for modules to start debugging suspend resume function, this patch adds standby suspend for now. Will add last CPU power down suspend function when SCFW is ready. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
2017-09-06i.mx8qm/i.mx8qxp: psci: add power off supportAnson Huang
Add system_off pcsi callback to avoid below kernel message when doing power off: [11613.953711] reboot: Power down [11613.958318] systemd-shutdow: 8 output lines suppressed due to ratelimiting [11613.965285] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00 [11613.965285] [11613.974441] CPU: 0 PID: 1 Comm: systemd-shutdow Not tainted 4.9.11-03354-g0e1 [11613.982369] Hardware name: Freescale i.MX8QXP LPDDR4 ARM2 (DT) [11613.988216] Call trace: [11613.990681] [<ffff0000080882bc>] dump_backtrace+0x0/0x1a8 [11613.996092] [<ffff000008088478>] show_stack+0x14/0x1c [11614.001154] [<ffff0000083aaf98>] dump_stack+0x8c/0xac [11614.006213] [<ffff000008162aac>] panic+0x124/0x28c [11614.011016] [<ffff0000080c0b20>] complete_and_exit+0x0/0x20 [11614.016600] [<ffff0000080dc6d8>] SyS_reboot+0x168/0x244 [11614.021829] [<ffff000008082ef0>] el0_svc_naked+0x24/0x28 [11614.027153] Kernel Offset: disabled [11614.030646] Memory Limit: none [11614.040755] ---[ end Kernel panic - not syncing: Attempted to kill init! exi0 [11614.040755] As there is no system power off SCFW API available now, so just simply do wfi and never return when system_off is called.

2017-08-25i.mx8qm/i.mx8qxp: add SIP cpu-freq supportAnson Huang
Linux kernel will issue cpu-freq scale via SIP, ATF calls SCFW API to finish the CPU frequency scale. Move SIP service code from i.mx8mq to common place for all i.mx SoCs. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
2017-07-21imx8qm/qxp: Reserve memory region for ATFYe Li
Reserve the memory region that is only can access by ATF. ATF is running in this memory region, while masters in other partitions can't access it. Signed-off-by: Ye Li <ye.li@nxp.com>
2017-07-19imx8qm/qxp: Modify the memory regions allocation to NS partitionYe Li
Change to search the ATF owned memory regions and assign them to non-secure OS partition. Not allocate new memory region for each one. Signed-off-by: Ye Li <ye.li@nxp.com>
2017-07-12imx8qm/imx8qxp: no need to disable console in plat runtime setupAnson Huang
As we already have control for debug console in platform_def.h, so no need to un-initialize console in plat runtime setup, just overwrite the common implementation with blank function. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

2017-07-12iMX8QM/QXP: Allocate memory regions to NS partitionYe Li
Not only the resources, but also the memory regions need to assign to non-secure partition. Otherwise, when the boot partition is secured, the OS non-secure partition can't access any memory. This patch currently assign all memory to NS partition, since it is not isolated, the current secure partition also can access them. In future, may need to change the regions for reserving some memory in secure partition for ATF and BL32. Signed-off-by: Ye Li <ye.li@nxp.com>
