In the default configuration, these images are written to regular MTD partitions, which means they are available as regular MTD devices in Linux. You can list all MTD devides with
A typical output would be:
There you'll see that the kernel is on mtd5 and the device tree on mtd6. More detailled information about these devices can be found in /sys/class/mtd/mtd<n> where <n> is 5 or 6 in this case. And you can read and write data via /dev/mtd<n>.
Remark:
The Kernel and FDT partitions are marked as read-only in U-Boot so that they are not overwritten unintentionally. So if you want to write data to them in Linux, you have to remove the read-only flag in U-Boot first.
