Without socfpga_sdram_apply_static_cfg(), the system hangs when Linux calls altvipfb2_start_hw() of the Intel Video and Image Processing(VIP) Frame Buffer II driver (drivers/video/fbdev/altvipfb2.c)

There is no such driver in mainline U-Boot or Linux.

, but only after a power cycle (cold boot). The issue does not show up after a soft reset (warm boot) and with v2018.11.

See the commit message of the patch this is reverting, I believe there is a deeper issue with the static config register. Can you investigate?
