OpenBSD uses the addr word to retrieve the address of several framebuffer variables during initialisation. Provide an implementation of addr which allows OpenBSD to initialise the framebuffer correctly on SPARC32 and SPARC64.

I don't believe that the project has an official TODO list (other than what people's time/interest allows), but the first thing to do is to have a read of the basics on https://www.openfirmware.org/ and decide which architecture you would like to study. Normally this is influenced by people who want to boot a particular OS under QEMU which is currently the main user for OpenBIOS for SPARC and PPC32.
The next step is to find or build yourself a suitable cross-compiler if working on x86 for which there are plenty of guides on the internet such as https://wiki.osdev.org/GCC_Cross-Compiler and then see if you can checkout the OpenBIOS code from github and build it successfully.
ATB,
Mark.
