[U-Boot] [U-boot] himport_r() function question

Hi, experts:

Set_default_env() function will call himport_r() function.

Himport_r() will create hash tables for env variables.

But on some very slow software emulator platform, himport_r() run very slowly!

So , my question is:

Would Himport_r() be omitted in set_default_env() ?

Best wishes,
