| |
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jaccon Bastiaansen <jaccon.bastiaansen@gmail.com>
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.
