* SMF: Memory Distribution Logic ImprovementsIlya Smirnov2019-03-011-27/+13
| | | | | | | | | | | | | | | | | | An improvement to the memory distribution logic was suggested in which the variable that keeps track of doubling the amount of memory per pass could be removed. This commit removes the variable and introduces a couple of other small changes.

* SMF: NVRAM Reading and Mem Distribution end-to-end ChangesIlya Smirnov2019-01-101-3/+3
| | | | | | | | | | | | | | | | | This commit introduces the changes to read out the SMF secure memory amount value from NVRAM and to distribute the secure memory amount based on the value read. strtou64 was copied from runtime code to convert the value read from NVRAM (as a string) to uint64_t.

* SMF: Distribute Secure Memory Among ProcsIlya Smirnov2018-11-271-0/+343
Logic for distributing the requested amount of SMF memory between the procs with memory on the system. The algorithm attempts to allocate the memory in power-of-two increments of 256MB (such is the HW limitation) under each proc until the requested amount is satisfied or until we run out of procs with memory.
