Hi!
I am trying to understand the state of the socfpga preloader in mainline u-boot.
From what I see, this is broken and perhaps has never worked.
That's correct AFAICT.
When I build the code in u-boot-socfpga I get a healthy working u-boot-spl.bin of approx 45kbytes.
When I build the mainline u-boot code I get a broken u-boot-spl.bin of approx 3kbytes.
It seems the mainline u-boot is missing stuff, including the all-critical sdram initialisation without which the SPL is useless.
Are you able to build working u-boot proper from recent sources?
I know u-boot SPL misses critical parts, but I was told that u-boot proper should have everything. Only... I was not able to get it to work. [I'm attempting to load recent u-boot from patched/old u-boot; I know this is not exactly recommended, but due to spl/proper split, it should work AFAIK... and does for old versions.]
Any ideas?
Thanks, Pavel
