How to split core & peri images? (QSPI boot)

I am using Arria10 SOC Dev kit.(QSPI boot) And I am porting Kernel using new method as below.

But new image building methods doesn’t explain the Early IO release.

So I tried to download fpga image using JTAG and it was taken almost 3 hours.
It’s terrible. Why are you make works difficult???

Do you have any ideas?

Older version kernel compile method also meaningless.
Because there is no meta-altera folder on Altera Opensource · GitHub It is disappeared. But compile script uses that missing folder.

It’s terrible. I will recommend my customer to use the SD card boot method.
