Okay, I've bisected this. TLDR: Linux and u-boot seem to have nothing to do with it, opensource TF-A doesn't work, binary BL31 starting with v1.09 do not work. BL31 v1.08 and earlier work fine.
v1.09 added support for 1 GHz hrtimer in addition to the normal 24 MHz rate. Mainline U-Boot may only support use of 24 MHz hrtimer, unsure what impact the hrtimer rate has. Mixing blobs with/without 1 GHz support is known to cause issues. At one point the latest rkbin tree may have contained incompatible rk3576 blobs (mixed 1 ghz vs 24 mhz rate). Did you try with newer blobs, i.e. ddr init v1.09, bl31 v1.19 blobs [1] and mainline U-Boot [2] ?

just fyi: to confirm: replacing only bl31 to 1.08 makes all good with perf gov. clocks staying on 2200/2300 clock estimations are predictable, constant and estimating constantly 2400 ux is „like” on 3588 Alexey: many thx for finding root cause component!
