Ok, thanks.
I used an xtfpga board that's not in the mainline, for the xtensa
architecture that's not in the mainline as well.
I've tried to build nokia_rx51 board (ARM) with enabled UBIFS and
indeed it got linked without errors. But then I've noticed that the
resulting u-boot image is dynamic executable and it has unresolved
external links to the same functions as listed above.
The difference between linking steps for ARM and xtensa is that
ARM image gets linked with -pie while xtensa u-boot is not and the
resulting u-boot image for xtensa is static.
I'm curious about how that's supposed to work.
