The debug_ll_outhexw macro has no dependency on UART model
so we can remove it from UART-dependent header files (debug_ll_ns16550.h
and mach-ath79/.../debug_ll.h).
On the other hand the only debug_ll_outhexw user is MIPS nmon monitor
so we can move the debug_ll_outhexw macro to pbl_nmon.h.

The defconfig files are long untouched and a
make xy_defconfig; make savedefconfig usually generates quite
a different looking file. Refresh them to make it easier to generate
patches against the configs using
make xy_defconfig; make menuconfig; make savedefconfig
This has been done with the following script.
for a in arch/*; do
arch=$(basename $a)
for c in $a/configs/*; do
config=$(basename $c)
export ARCH=$arch
make $config && make savedefconfig && mv defconfig $c
done
done

Of_unflatten_dtb returns a ERR_PTR value so checking it against NULL is

At the moment barebox tplink-mr3020.dts file has almost
the same content as linux ar9331_tl_mr3020.dts file
so we can reuse linux dts-file and drop duplicated lines
from barebox dts-file.

bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.

U-Boot_mod is a popular bootloader for Atheros AR93xx chips,
please see https://github.com/pepe2k/u-boot_mod for details.
It's reasonable to import some lowlevel AR9331 initialization
code from U-Boot_mod.
AR9331 (Hornet) 1.1 currently needs an additional
reset at 1st boot. This patch imports necessary code
from u-boot_mod/u-boot/cpu/mips/start_bootstrap.S.

TP-Link MR3020 has 4 MiB flash boot ROM.
Usually boot ROM is mapped to 0xbfc00000.
However, as AR9331 allows to remap boot ROM to 0xbf000000
it's better to assume that boot ROM starts at 0xbf000000.
