2020-05-15firmware: xilinx: Fix an error handling path in 'zynqmp_firmware_probe()'Christophe JAILLET1-2/+2
If 'mfd_add_devices()' fails, we must undo 'zynqmp_pm_api_debugfs_init()' otherwise some debugfs directory and files will be left. Just move the call to 'zynqmp_pm_api_debugfs_init()' a few lines below to fix the issue.

These functions were added to drivers/fpga/zynqmp-fpga.c but not exported so the module build breaks. Export them so that they can be used in modules properly.

2020-04-28firmware: xilinx: Add sysfs and API to set boot health statusRajan Vaja1-0/+39
Add sysfs interface to set boot health status from user space. Add API used by this interface to communicate with firmware. If PMUFW is compiled with CHECK_HEALTHY_BOOT, it will check the healthy bit on FPD WDT expiration. If healthy bit is set by a user application running in Linux, PMUFW will do APU only restart. If healthy bit is not set during FPD WDT expiration, PMUFW will do system restart.

2020-04-28firmware: xilinx: Add sysfs to set shutdown scopeRajan Vaja1-1/+97
The Linux shutdown functionality implemented via PSCI system_off does not include an option to set a scope, i.e. which parts of the system to shut down. This patch creates sysfs that allows to set the shutdown scope for the next shutdown request. When the next shutdown is performed, the platform specific portion of PSCI-system_off can use the chosen shutdown scope.

2019-03-18firmware: xilinx: fix debugfs write handlerJann Horn1-11/+4
- Userspace wants to write a string with `len` bytes, not counting the terminating NULL, so we should allocate `len+1` bytes. It looks like the current code relied on having a nullbyte directly behind `kern_buff`, which happens to work reliably as long as `len` isn't one of the kmalloc size classes. - strncpy_from_user() is completely wrong here; userspace is giving us a (not necessarily null-terminated) buffer and its length. strncpy_from_user() is for cases in which we don't know the length. - Don't let broken userspace allocate arbitrarily big kmalloc allocations. Just use memdup_user_nul(), which is designed precisely for things like this.
