Bootloader Programming

The following sections describe bootloader programming.

DRAM Training Restriction

When creating DRAM DVFS tables using BPMP-FW-DTB, the BPMP-FW only supports hardware-based periodic DRAM training and frequencies higher than 1600Mhz. The BPMP-FW signals to HSM and halts boot if a software-based periodic training is needed for a DRAM DVFS table entry.
