Hi! Speaking as a small part-time contributor of some Netgear WN(D)R routers code, please reconsider if jumping over 4.19 straight to 5.4 is not a too big leap. I'm sure kernel devs here knows better than me how many OpenWrt drivers, quirks and enhancements can be ported without too much effort from 4.14 to 5.4 that will really benefit from newer 5.x code, but here are my 5 cents.
I was able to port ar934x-nand code from ar71xx 4.4 kernels to ath79 & device-tree 4.19 without going too deep into low-level NAND operations thanks to only minor changes in kernel code. 5.4 apparently deprecates some functions in that area providing 'legacy' knobs for who-knows-how-long. If this particular flash driver won't work with 5.4 at the time of 20.x, routers using it (like WNDR4300 and other AR9344-based) effectively will not have any stable OpenWrt release supporting it even though they were in master since the end of 2019. IMHO OpenWrt should have an one final, rock-stable release based on latest 4.x LTS kernel (4.19 that is) with ath79 replacing ar71xx whenever possible. Apologies for being so Atheros-centric :-) Cheers Michal _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
