2020-08-24mrc_cache: Add mrc_cache fetch functions to support non-x86 platformsShelley Chen
Create two new functions to fetch mrc_cache data (replacing mrc_cache_get_current): - mrc_cache_load_current: fetches the mrc_cache data and drops it into the given buffer. This is useful for ARM platforms where the mmap operation is very expensive. - mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a given buffer. This is useful for platforms where the mmap operation is a no-op (like x86 platforms). As the name mentions, we are not freeing the memory that we allocated with the mmap, so it is the caller's responsibility to do so. Additionally, we are replacing mrc_cache_latest with mrc_cache_get_latest_slot_info, which does not check the validity of the data when retrieving the current mrc_cache slot. This allows the caller some flexibility in deciding where they want the mrc_cache data stored (either in an mmaped region or at a given address).

Add comments found when testing ECC scrubbing code. This is a cosmetic change.

2020-08-11nb/intel/sandybridge/raminit: Fix ECC scrubPatrick Rudolph
The scrubbing method was never correct nor tested. Fix that by observations made on mrc.bin. Tested on HP Z220 with ECC memory and Xeon E3 CPU: The whole memory is now scrubbed.

2020-08-11nb/intel/sandybridge/raminit: Add ECC debug codePatrick Rudolph
* Add ECC test code when DEBUG_RAM_SETUP is enabled * Move ECC scrubbing after set_scrambling_seed() to be able to observe what has been cleared in the test routine. If clearing happens before set_scrambling_seed the data is XORed with a different PRN. Data read from memory will look random instead of all zeros. * ECC scrubbing must happen after dram_dimm_set_mapping() The ECC logic is set to "normal mode" in dram_dimm_set_mapping(). In normal mode the ECC bits are calculated and stored on write transactions. * Move method out of try_init_dram_ddr3(). This satisfies point 2 and point 3 of the list above.
