www.firmware.org doesn't resolve for me. I found these equivalent URLs by taking the redirects from the previous (openfirmware.org) URLs, as seen before commit f517256a6867 ("Documentation/devicetree: Update PCI Device Tree bindings") updated them. Signed-off-by: Brian Norris <briannorris@xxxxxxxxxxxx> --- This is my best attempt at a resolution. I'm not sure what firmware.org is or if its owner is even legit. It does seem like openfirmware.info is a proper successor to openfirmware.org, and it's registered to a coreboot dev.
