Please add information about the MAC addresses to the commit message, as suggested in the previous e-mail, something like

0x4        *:00  wlan2g/wan/label 
0x8004 *:01  wlan5g 
0xe000 *:02  lan 
0xe006 *:03  not used in stock FW

For mt7621, state_default is already defined in mt7621.dtsi. So, you may use it directly:

 +&state_default {
 +	gpio {
 +		ralink,group = "i2c", "uart3", "jtag", "wdt";
 +		ralink,function = "gpio";
 +	};
 +};

I've built a patch to allow kilobytes here:
https://git.openwrt.org/?p=openwrt/staging/adrian.git;a=shortlog;h=refs/heads/staging

I'm currently built-testing it, maybe you can test with
JCG_MAXSIZE := 16064k
too.

Best
