When TCGBIOS is enabled on a machine without a physical TPM, SeaBIOS takes over half a minute to print to the display, and over another half minute before handing control over to a boot device. Disable this option by default to have it be an explicit choice.
Tested on a Dell Inspiron 660s (no TPM) configured with libgfxinit, and, separately, configured with a PCIe video card with onboard VGA BIOS.

I reported the same issue with the ASRock E350M1. Please test the patches on the mailing list, if they fix the issue for you.
Kind regards,
