> BTW I swapped these 2 functions and Krane booted correctly.

the EMI setting(EMI registers) only need do once, is not relationship with the DRAM frequency.
so only need do all EMI setting once.
Attention, the bootup sequence of is very importance for DRAM, otherwise system maybe not-stable. All changes need be confirmed with the DRAM designer team, some changes maybe need do hardware simulation(those maybe take several weeks).
