My board will be configured via DTS file, that contains an MTD
partition table [1]. How can it be automatically exported to
global.inux.bootargs.mtdparts?

Why would you want to do that? You are not going to start an ancient
kernel with ATAG support, are you?

So far I'm using ancient LTS 3.18.x kernel with this DTS [1] and
packaging it via FIT.

I've installed dtc and dumped my loaded DTB in Linux:
nand@0,0 {
reg = <0x0 0x0 0x4>;
gpmc,we-off-ns = <0x28>;
gpmc,oe-on-ns = <0x0>;
gpmc,device-nand = "true";
gpmc,cycle2cycle-delay-ns = <0x0>;
gpmc,wr-access-ns = <0x28>;
gpmc,wr-data-mux-bus-ns = <0x0>;
gpmc,adv-rd-off-ns = <0x22>;
gpmc,oe-off-ns = <0x36>;
gpmc,clk-activation-ns = <0x0>;
gpmc,wait-on-write = "true";
elm_id = <0x42>;
ti,nand-ecc-opt = "bch8";
gpmc,adv-on-ns = <0x6>;
gpmc,adv-wr-off-ns = <0x2c>;
ti,nand-xfer-type = "prefetch-polled";
gpmc,wait-monitoring-ns = <0x0>;
nand-bus-width = <0x8>;
gpmc,device-width = <0x1>;
gpmc,cs-rd-off-ns = <0x2c>;
gpmc,rd-cycle-ns = <0x52>;
#address-cells = <0x1>;
gpmc,bus-turnaround-ns = <0x0>;
gpmc,cs-on-ns = <0x0>;
gpmc,we-on-ns = <0x0>;
#size-cells = <0x1>;
gpmc,wait-on-read = "true";
gpmc,wr-cycle-ns = <0x52>;
gpmc,access-ns = <0x40>;
gpmc,sync-clk-ps = <0x0>;
gpmc,cs-wr-off-ns = <0x2c>;
partitions {
compatible = "fixed-partitions";
#addres-cells = <0x1>;
#size-cells = <0x1>;
partition@260000 {
reg = <0x260000 0xfda0000>;
label = "UBI";
};
partition@0 {
reg = <0x0 0x20000>;
label = "SPL";
};
partition@20000 {
reg = <0x20000 0x20000>;
label = "SPL.backup1";
};
partition@40000 {
reg = <0x40000 0x20000>;
label = "SPL.backup2";
};
partition@60000 {
reg = <0x60000 0x20000>;
label = "SPL.backup3";
};
partition@80000 {
reg = <0x80000 0x1e0000>;
label = "u-boot";
};
};
};
Somehow UBI partition is now the first partition and thus other
partitions were not parsed. Cat /proc/mtd says nothing and I have only
/dev/mtd0.

The partition ordering is strange, but not your problem. You only have
mtd0 because the old Kernel doesn't recognize any partition table at
all, note the additional partitions{} subnode which is only recognized
by newer kernels. You have to set global.of_partition_binding="legacy".

I see now. It is working with the legacy option.
Thanks.
