mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-5.8.3-kirkwood-tld-1 -d /boot/dts-5.8.3/kirkwood-nsa310.dtb  ./uImage-5.8.3
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs-5.8.3-kirkwood-tld-1 -d ./initrd.img-5.8.3-kirkwood-tld-1 ./uInitrd-5.8.3

And configure U-Boot to boot form new image:

fw_setenv load_ide_58 'ide reset; ext2load ide 0:3 0x800000 /uImage-5.8.3; ext2load ide 0:3 0x1100000 /uInitrd-5.8.3;'
fw_setenv bootcmd_ide_58 'run load_ide_58; bootm 0x800000 0x1100000;'
fw_setenv bootcmd 'run load_ide_58; bootm 0x800000 0x1100000;'
