[PATCH] startup: Load default environment earlier

2018-02-05 Thread Sascha Hauer 
Some files compiled into the default environment may be needed earlier in
the boot process, so move loading of the default environment to fs_initcall.
Only the default environment is loaded earlier, but not the overwriting with
the persistent environment files, so when the files are used that early, only
the compiled in version is available; it's not overwritable at that
time.

Yes/no/further discussion needed? :)

The old way does not seem to work for RPi 3, as the UART pins are
mapped differently and the NOOBS bootcode does not seem to read a

-  1. Prepare a card with a FAT filesystem. Download a tiny NOOBS LITE

- zip archive and unpack it into FAT partition.
- See http://www.raspberrypi.org/help/noobs-setup/ for details.
+  1. Prepare an SD or microSD card with a FAT filesystem of at least 30 MB in 
size.
+
+  2. Download the `Raspberry Pi firmware`_ (120 MB), unzip it, and copy the
+ contents of the ``boot/`` folder to your card.
  
-  2. Compile ``barebox.bin`` image (use ``rpi_defconfig``).

- Copy it to the SD/microSD card and name it ``recovery.img``.
+  3. Use ``make rpi_defconfig; make`` to build barebox. This will create the 
following images:
  
-  3. Connect to board's UART (115200 8N1);

(Raspberry Pi 1)
+ - ``images/barebox-raspberry-pi-2.img`` for the BCM2836/CORTEX-A7 
(Raspberry Pi 2)
+ - ``images/barebox-raspberry-pi-3.img`` for the BCM2837/CORTEX-A53 
(Raspberry Pi 3, Raspberry Pi Zero)
+
+ Copy the respective image for your model to your SD card and name it
+ ``barebox.img``.
+
+  4. Create a text file ``config.txt`` on the SD card with the following 
content::
+
+ kernel=barebox.img
+ enable_uart=1
+ dtoverlay=pi3-miniuart-bt
+
+ (For more information, refer to the `documentation for config.txt`_.)
+
+  5. Connect to board's UART (115200 8N1);
   Use PIN6 (GND), PIN8 (UART_TX), PIN10 (UART_RX) pins.
  
-  4. Turn board's power on.

+  6. Turn board's power on.

No, barebox currently only supports the AM335x from the industrial IT
SoC series (found for example on the beaglebone). There is no code for
the AM4* and AM5* SoCs.
