Hi Simon,

Changes since v1:
- Tokenize the DT node entry and use the appropriate value instead of the entire string
- Removed Peters tested/reviewed-by tags due to the above

Can this be put behind a Kconfig? It adds quite a bit of code which punishes those boards which do the right thing.
Sure but OTOH the code increase should be really minimal. But I don't mind I can add a Kconfig
dt_str = ofnode_read_string(ofnode_root(), nprop->dt_str);Could this use ofnode_read_string_index() ?
Maybe, I'll have a look and change it if that works
Unless I am missing something this doesn't work. This is designed to return a string index from a DT property that's defined as foo_property = "value1", "value2" isn't it?
The code above is trying to read an existing property (e.g compatible) and get the string after the comma delimiter. Perhaps I should add this in drivers/core/ofnode.c instead?

Any chance of a test for this code?
Sure, but any suggestions on where to add the test? SMBIOS tables are populated on OS booting, do we have a test somewhere that boots an OS?
They are written on startup, right? They should certainly be in place before U-Boot enters the command line.
Not always. I am not sure if x86 does that, but on the rest of the architectures, they are only initialized when the efi smbios code runs. Wasn't this something you were trying to change?
Any other ideas?
Probably a test in test/lib/ would work. We actually have smbios-parser.c which might help?
That doesn't seem too helpful either. But I can add a test in test/dm/ofnode.c if we move the parsing function to ofnode.c. The generic SMBIOS tests can be added when the SMBIOS code is refactored.
