Subject: sunxi: disable LPAE to allow kernel to run on A13
X-Git-Tag: v17.01.5~75
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fstaging%2Fchunkeey.git;a=commitdiff_plain;h=92ea65b36aa783f28accd01fa4850f3640d2c6b6

sunxi: disable LPAE to allow kernel to run on A13

Fixes issue FS#1355.
LPAE extensions are enabled, but the A13 does not support them.
The result is the boot process stopping at "Starting kernel ..."

Fixes: 468735c3a2f7 ("target: sunxi: enable kvm support")
