ipq806x: increase kernel partition size for the Netgear r7800
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 patch is based on a corresponding change by Pavel Kubelun <be.dissent@gmail.com> and has been tested by Michael Yartys <michael.yartys@protonmail.com> Signed-off-by: Stefan Lippers-Hollmann <s.l-h@gmx.de>
