mmc: Update environment variable with active partition 2021-06-22T04:02:46+00:00 Reuben Dowle reubendowle0@gmail.com 2021-05-13T22:15:43+00:00 5c2beda545dde4d27c0e893e97c74740ff27ff2f This patch allows uboot scripts make choices about where to boot from based on the active mmc boot partition. This allows having two copies of kernel, filesystems etc, and choosing which to boot from based off of the active bootloader partition.

cmd: add support for a new "extension" command 2021-05-13T17:09:05+00:00 Kory Maincent kory.maincent@bootlin.com 2021-05-04T17:31:22+00:00 2f84e9cf06d31aa703ff31301bf811b3fcfc16cf 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> 
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
