Subject: [U-Boot] [PATCH] ARM: socfpga: Remove socfpga_sdram_apply_static_cfg()

Hello,
after removing the function socfpga_sdram_apply_static_cfg() in 
misc_gen5 we can not use the FPGA2SDRAM bridge.

Without the apply static cfg the kernel crash every time,
if we try to write @ the fpga2sdram bridge. After an soft reset
everything is working.

If we add the socfpga_sdram_apply_static_cfg() in the
u-boot source code, everything is fine.
Now we can use the fpga2sdram bridge after power on.

Our setup:
- u-boot v2020.01
   - load and write fpga firmware
   - enable bridges
- boot linux

I have found some information at
