How are you planning on handling chip-specific errata? Do you forsee do_errata() containing code for every erratum of every chip?

Really? There is only 1 case, you want:
switch(SVR_SOC_VER(svr)) {

}Yes - don't you think it's much easier to write and to read?
Also it shows clearly that you are missing a default: case...
BTW: your indentation is wrong, and please sort the list...
