From: Stefan Lippers-Hollmann Date: Fri, 18 May 2018 01:49:27 +0000 (+0200) Subject: ipq806x: increase kernel partition size for the Netgear Nighthawk X4 D7800 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0882a4cf258cb227b4889a11cf55658129df9e7a;p=openwrt%2Fstaging%2Fdedeckeh.git ipq806x: increase kernel partition size for the Netgear Nighthawk X4 D7800 Starting with kernel 4.14 and gcc 7, the kernel doesn't fit into the 2 MB reserved for the kernel partition by the OEM firmware anymore. This patch increases the kernel partition from 2 MB to 4 MB, at the expense of the rootfs, for all supported kernels. WARNING: This breaks sysupgrade! Flashing a firmware containing this changed partitioning from an older image with 2 MB reserved for the kernel partion requires the tftp recovery procedure, thereby losing all settings. This change follows the functional example of the Netgear r7800, but has not been runtime tested on a Netgear Nighthawk X4 D7800.
