2020-09-16	soc/amd/picasso: Convert DDR4 MHz to MT/s correctly	Rob Barnes
	Memory speed is given as an integer in MHz. In some cases it has an implicit fractional speed, so simply multiplying by 2 is not sufficient. Use method from dram/ddr4.c instead.

2020-09-03	soc/amd/picasso: Set max_speed_mts and configured_speed_mts	Rob Barnes
	ddr_frequency is deprecated. Set max_speed_mts and configured_speed_mts instead. This will result in SMBIOS type 17 displaying more accurate speed information. BUG=b:167218112 TEST=Boot ezkinil and observe dmidecode -t17 dmidecode -t17 # dmidecode 3.2 Getting SMBIOS data from sysfs. SMBIOS 3.0 present.

2020-08-24	soc/amd/picasso: Store ddr_frequency in MT/s	Rob Barnes
	This field eventually gets interpreted as MT/s by SMBIOS instead of MHz. Translate from Mhz to MT/s by multiplying by 2.

	Extract DRAM info from AMD_FSP_DMI_HOB and store it as mem_info in cbmem with id CBMEM_ID_MEMINFO. Subsquently extract mem_info objects from cbmem to build SMBIOS type 17 tables.
