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.
Approval
