[PATCH 0/5] arm: socfpga: agilex5: cleanup SDRAM initialization

[Michael Tretter]

The Agilex5 SDRAM initialization contains some obscure and unclear
workarounds, which are supposedly necessary for a successful SDRAM
initialization.

I observed a race condition between the IOSSM firmware, which is
responsible for the SDRAM initialization, and barebox. I assume this
race is responsible for the observed initialization failures.

Add an explicit workaround including documentation for the race
condition and remove the other workarounds.
