75xx Kernel

The TS kernel is built from the same Linux sources Cavium Networks has tested and used on their CPU evaluation boards. There are no Technologic Systems specific drivers or kernel support implemented. Instead, there has been userspace driver support implemented for the SPI NOR flash, MicroSD cards, XNAND drive, battery-backed real-time clock, XUART serial port channels, watchdog, and GPIO pins. This allows easy migration to newer kernels when either Cavium or the mainline Linux kernel community creates them. In the past, constant Linux-internal API redesign required rewriting and revisiting custom drivers with each new kernel revision, in effect locking customers in to whatever kernel version was released and tested during initial product release. Being free to update to newer kernels in the future allows easier support of the new USB devices as those drivers tend to only be developed for the newest kernel sources.

We provide 2.6.24 as the supported kernel.

We also have 2.6.36, though USB device does not work (host does). This is provided as is.
