If anyone has any objections, please let me know. ------------------ From: Jaccon Bastiaansen commit 350ab15bb2ffe7103bc6bf6c634f3c5b286eaf2a upstream. The statically defined I/O memory regions for the i.MX21 on chip peripherals and the on board I/O peripherals of the i.MX21ADS board overlap. This results in a kernel crash during startup. This is fixed by reducing the memory range for the on board I/O peripherals to the actually required range.
