platform_data/mlxreg: Add new field for secured access

vadimp-nvidia · jwrdegoede · commit 9d93d7877c91 · 2021-10-19T10:41:56.000+02:00
Extend structure 'mlxreg_core_data' with the field "secured". The purpose of this field is to restrict access to some attributes, if kernel is configured with security options, like: LOCK_DOWN_KERNEL_FORCE_CONFIDENTIALITY. Access to some attributes, which for example, allow burning of some hardware components, like FPGA, CPLD, SPI, etcetera can break the system. In case user does not want to allow such access, it can disable it by setting security options.
