+U-Boot extension board usage (CONFIG_EXTENSION)
+===============================================
+
+Synopsis
+--------
+
+::
+
+    extension scan
+    extension list
+    extension apply <extension number|all>
+
+Description
+-----------
+
+The "extension" command proposes a generic U-Boot mechanism to detect
+extension boards connected to the HW platform, and apply the appropriate
+Device Tree overlays depending on the detected extension boards.
+
+The "extension" command comes with three sub-commands:
+
+ - "extension scan" makes the generic code call the board-specific
+   extension_board_scan() function to retrieve the list of detected
+   extension boards.
+
+ - "extension list" allows to list the detected extension boards.
+
+ - "extension apply <number>|all" allows to apply the Device Tree
+   overlay(s) corresponding to one, or all, extension boards
+
+The latter requires two environment variables to exist:
+
+ - extension_overlay_addr: the RAM address where to load the Device
+   Tree overlays
+
+ - extension_overlay_cmd: the U-Boot command to load one overlay.
+   Indeed, the location and mechanism to load DT overlays is very setup
+   specific.
+
+In order to enable this mechanism, board-specific code must implement
+the extension_board_scan() function that fills in a linked list of
+"struct extension", each describing one extension board. In addition,
+the board-specific code must select the SUPPORT_EXTENSION_SCAN Kconfig
+boolean.
+
+Usage example
+-------------
+
+1. Make sure your devicetree is loaded and set as the working fdt tree.
+
+::
+
+    => run loadfdt
+    => fdt addr $fdtaddr
+
+2. Prepare the environment variables
+
+::
+
+    => setenv extension_overlay_addr 0x88080000
+    => setenv extension_overlay_cmd 'load mmc 0:1 ${extension_overlay_addr} /boot/${extension_overlay_name}'
+
+3. Detect the plugged extension board
+
+::
+
+    => extension scan
+
+4. List the plugged extension board information and the devicetree
+   overlay name
+
+::
+
+    => extension list
+
+5. Apply the appropriate devicetree overlay
+
+For apply the selected overlay:
+
+::
+
+    => extension apply 0
+
+For apply all the overlays:
+
+::
+
+    => extension apply all
+
+Simple extension_board_scan function example
+--------------------------------------------
+
+.. code-block:: c
+
+    int extension_board_scan(struct list_head *extension_list)
+    {
+        struct extension *extension;
+
+        extension = calloc(1, sizeof(struct extension));
+        snprintf(extension->overlay, sizeof(extension->overlay), "overlay.dtbo");
+        snprintf(extension->name, sizeof(extension->name), "extension board");
+        snprintf(extension->owner, sizeof(extension->owner), "sandbox");
+        snprintf(extension->version, sizeof(extension->version), "1.1");
+        snprintf(extension->other, sizeof(extension->other), "Extension board information");
+        list_add_tail(&extension->list, extension_list);
+
+        return 1;
+    }

Gilbert Gilb's	adec30ace4	fix(c9xx): don't flush dcache when invalidating The data cache invalidation function for c9xx CPUs uses `dcache.cipa` instruction. According to T-Head extension specification[1] section 3.1.5, this instruction also performs a cache clean along with the invalidation. On top of being incorrect, this leads to a serious issue on the designware ethernet driver, where stalled cache may get flushed each time we handle a new received packet[2]. As a result, received packet are randomly corrupted with old cached data. This can easily be reproduced by sending an ARP request to the device during a TFTP transfer. The last TFTP block is treated as the ARP reply we just sent, which makes U-Boot hang on the block. Always use `dcache.ipa` instruction to invalidate dcache. Replace existing usages of `dcache.ipa` with our implementation. Note that this fix is slightly intrusive as it changes the cache invalidation behavior in all drivers. However, I have not noticed any side-effect during my tests.

Kory Maincent	c86cc5402a	cmd: add support for a new "extension" command This patch adds a new "extension" command, which aims at detecting extension boards connected to the hardware platform, and apply the Device Tree overlays that describe the hardware present on those extension boards. In order to enable this mechanism, board-specific code must implement the extension_board_scan() function that fills in a linked list of "struct extension", each describing one extension board. In addition, the board-specific code must select the SUPPORT_EXTENSION_SCAN Kconfig boolean. Based on this: - "extension scan" makes the generic code call the board-specific extension_board_scan() function to retrieve the list of detected extension boards. - "extension list" allows to list the detected extension boards. - "extension apply <number>\|all" allows to apply the Device Tree overlay(s) corresponding to one, or all, extension boards The latter requires two environment variables to exist and set one variable to run: - extension_overlay_addr: the RAM address where to load the Device Tree overlays - extension_overlay_cmd: the U-Boot command to load one overlay. Indeed, the location and mechanism to load DT overlays is very setup specific. - extension_overlay_name: set by the command: the name of the DT which will be load during the execution. When calling the command described in the extension_overlay_cmd variable, the variable extension_overlay_name will be defined. So a typical extension_overlay_cmd will look like this: extension_overlay_cmd=load mmc 0:1 $extension_overlay_addr /boot/$extension_overlay_name Here is an example on how to use it: => run loadfdt => fdt addr $fdtaddr => setenv extension_overlay_addr 0x1000 => setenv extension_overlay_cmd 'load mmc 0:1 ${extension_overlay_addr} /boot/${extension_overlay_name}' => extension scan Found 1 extension board(s). => extension apply 0 519 bytes read in 3 ms (168.9 KiB/s) Signed-off-by: Kory Maincent <kory.maincent@bootlin.com> Reviewed-by: Maxime Ripard <maxime@cerno.tech>	2023-10-20 13:38:37 +08:00
