-NOTE: All Raspberry Pi computers report `BCM2835`, even those with BCM2836, BCM2837, BCM2711, and BCM2712 processors. You should not use this string to detect the processor. Decode the revision code using the information below, or `cat /sys/firmware/devicetree/base/model`.

Decode the revision code using the information below, or `cat /sys/firmware/devicetree/base/model`. Depending on which kernel you're running, your `cpuinfo` might also have a "Model" line, and might not have a "Hardware" line.
