Hi,
I found some issues with SPL where silicons were not properly detected.
This series is fixing this and also fixing some minor related issues.
Thanks,
Michal

xilinx_pm_request() can failed that's why also check return value.

U-Boot SPL on ZynqMP is using CONFIG_SPL_USE_TINY_PRINTF which doesn't
return any return value and all the time returns 0. That's why
even correct snprintf was returning in SPL chip ID as "unknown".
Change checking condition and allow snprintf to return 0 which is according
manual patch successful return.
"If an output error is encountered, a negative value is returned."
