Distinguishing hardware revisions

Inside the Bootloader

Every hardware revision has its own u-boot image type. Thus, the bootloader has the revision hard-coded. The hardware revision is passed on to the kernel via the ATAG mechanism (ATAG_REVISION)

Inside the Kernel

The kernel receives the ATAG_REVISION during bootup, and saves its contents in the "system_rev" global variable.

From Userspace

The kernel exports the system_rev variable in /proc/cpuinfo as "Revision :" line.
