Why not putting this into the _defconfig?
(On my device, it's neither in defconfig nor in Kconfig, I only had it
on in the initial "bring it to live" period. Afterwards I turned it
off)

I suppose you are mixing up HAS_DEBUG_LL with DEBUG_LL.
DEBUG_LL depends on HAS_DEBUG_LL. If HAS_DEBUG_LL=y then DEBUG_LL can be enabled or DEBUG_LL can be disabled.
So you have no chance to use DEBUG_LL without HAS_DEBUG_LL=y!
If you want to enable HAS_DEBUG_LL you have to explicitly select it in a Kconfig file.
You can't use just _defconfig for HAS_DEBUG_LL enabling.

The MB 77.07 is a small (80x80 mm) single-board computer
developed in Russia by the RC Module.
It was developed as an educational board for К1879ХБ1Я SoC
capabilities demonstration.
See http://www.module.ru/en/catalog/micro/micro_pc/ for details.

+The board uses MBOOT as bootloader.

+Barebox mini-howto:
+
+1. Connect to the boards's UART (38400 8N1);
+
+2. Turn board's power on;
+
+3. Wait 'Hit any key (in 2 sec) to skip autoload...' prompt and press the space key;
+
+4. Compile zbarebox.bin image and upload it to the board via tftp
+@verbatim
+ MBOOT # tftpboot zbarebox.bin
+ greth: greth_halt
+ TFTP Using GRETH_10/100 device
+ TFTP params: server 192.168.0.1 our_ip 192.168.0.7
+ TFTP params: filename 'zbarebox.bin' load_address 0x40100000

+ TFTP done

+
+5. Run barebox
+@verbatim
