Clocks 0 to 31 are on CKENA, and not CKENB. The clock register names were inadequately inverted. As a consequence, all clock operations were happening on CKENB, because almost all but 2 clocks are on CKENA. As the clocks were activated by the bootloader in the former tests, it escaped the testing that the wrong clock gate was manipulated. The error was revealed by changing the pxa3xx-nand driver to a module, where upon unloading, the wrong clock was disabled in CKENB.
