TL-WR1043NDv2 and mips74kc

Hi all,

I have TL-WR1043NDv2, I've installed the 19.07.1 on it using the default image:

Install image link 19.07.1-ath79

When I check the boot info it shows that the system supports mips74kc:

[ 0.000000] CPU0 revision is: 00019750 (MIPS 74Kc)
[ 0.000000] MIPS: machine is TP-Link TL-WR1043ND v2
[ 0.000000] SoC: Qualcomm Atheros QCA9558 ver 1 rev 0

But the default package feed URL points to mips24kc section:

src/gz openwrt_core
src/gz openwrt_kmods
src/gz openwrt_base
src/gz openwrt_luci
src/gz openwrt_packages
src/gz openwrt_routing
src/gz openwrt_telephony

From the above I'd say that the default image for this type of router is made using the mips24kc package architecture. Is this statement correct?

Is it possible to get (or create myself) a build made for mips74kc package architecture? Where to get it or how to make it? Would the build run in the router without problems? Would it bring any performance increase?

Thank you.
