Even though this was brought up in upstream discussion [1] it missed my patches: users should prefer <oemStrings/> over fwcfg. The reason is that fwcfg is considered somewhat internal to QEMU and it has limited number of slots and neither of these applies to <oemStrings/>.
While I'm at it, I'm fixing the example too (because it contains incorrect element name) and clarifying sysfs/ exposure.

It's nice that you say that, but people who would like to use fw_cfg for passing in a huge blob, which is saved in a file, will read this, go to <oemStrings/> and see that there is no way to pass a file as an input. Should that be dealt with somehow? Or would that be discouraged as well?
Unfortunately, QEMU doesn't allow reading OEM strings from a file (at least quick glance over hw/smbios/smbios.c doesn't show any signs it's allowed). Michal
