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] ?
