2016-11-21device/dram/ddr3: Fix calculation CRC16 of SPDKyösti Mälkki
Fix regression with commit: 7dc4b84 device/dram/ddr3: Calculate CRC16 of SPD unique identifier Misplaced parenthesis causes CRC check failure, potentially rendering some platform unbootable.

2016-11-20device/dram/ddr3: Calculate CRC16 of SPD unique identifierKyösti Mälkki
Specification allows for the unique identifier bytes 117..125 to be excluded of CRC calculation. For such SPD, the CRC would not identify replacement between two identical DIMM parts, while memory training needs to be redone.

2016-02-20nb/intel/sandybridge/raminit: Add XMP supportPatrick Rudolph
Some vendors store lower frequency profiles in the regular SPD, if the SPD contains a XMP profile. To make use of the board's and DIMM's maximum supported DRAM frequency, try to parse the XMP profile and use it instead. Validate the XMP profile to make sure that the installed DIMM count per channel is supported and the requested voltage is supported. To reduce complexity only XMP Profile 1 is read. Allows my DRAM to run at 800Mhz instead of 666Mhz as encoded in the default SPD.

It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2013-06-04DDR3: Add utilities for creating MRS commandsAlexandru Gagniuc
MRS commands are used to tell the DRAM chip what timing and what termination and drive strength to use, along with other parameters. The MRS commands are defined by the DDR3 specification [1]. This makes MRS commands hardware-independent. MRS command creation is duplicated in various shapes and forms in any chipset that does DDR3. This is an effort to create a generic MRS API that can be used with any chipset. This is used in the VX900 branch.
