2021-04-09habanalabs: support legacy and new pll indexesOhad Sharabi1-2/+47
In order to use minimum of hard coded values common to LKD and F/W a dynamic method to work with PLLs is introduced in this patch. Formerly asic specific PLL numbering is now common for all asics. To be backward compatible a bit in dev status is defined, if the bit is not set LKD will keep working with old PLL numbering.

2020-09-22habanalabs: add indication of security-enabled F/WOded Gabbay1-7/+48
Future F/W versions will have enhanced security measures and the driver won't be able to do certain configurations that it always did and those configurations will be done by the firmware. We use the firmware's preboot version to determine whether security measures are enabled or not. Because we need this very early in our code, the read of the preboot version is moved to the earliest possible place, right after the device's PCI initialization.

ArmCP mandates that the device CPU is always an ARM processor, which might be wrong in the future. Most of this change is an internal renaming of variables, functions and defines but there are two entries in sysfs which have armcp in their names. Add identical cpucp entries but don't remove yet the armcp entries. Those will be deprecated next year. Add the documentation about it in sysfs documentation.
