* mvebu: disable cpu idle on WRT1900ACv1Felix Fietkau2018-03-191-0/+10
A regression seriously affecting the Linksys WRT1900ACv1 (Mamba) was introduced some time between the OpenWrt/LEDE v4.4 and v4.9 kernels. The root cause has not yet been identified, despite many attempts for more than a year. Disabling the SoC specific CPU idle support should mitigate this issue. The symptoms on an affected system are unwanted reboots at a variable frequency. In many cases almost immediately after boot, causing a bootloop. This effectively disables support for Mamba on OpenWrt with kernels > v4.4. Signed-off-by: Felix Fietkau <nbd@nbd.name>
