2021-05-13cmd: add support for a new "extension" commandKory Maincent
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>

2021-01-15cmd: Add MBR partition layout control utilityMarek Szyprowski
Add a 'mbr' command to let users create or verify MBR partition layout based on the provided text description. The partition layout is alternatively read from the 'mbr_parts' environment variable. This can be used in scripts to help system image flashing tools to ensure proper partition layout. The syntax of the text description of the partition list is similar to the one used by the 'gpt' command. Supported parameters are: name (currently ignored), start (partition start offset in bytes), size (in bytes or '-' to expand it to the whole free area), bootable (boolean flag) and id (MBR partition type). If one wants to create more than 4 partitions, an 'Extended' primary partition (with 0x05 ID) has to be explicitely provided as a one of the first 4 entries. Here is an example how to create a 6 partitions (3 on the 'extended volume'), some of the predefined sizes: > setenv mbr_parts 'name=boot,start=4M,size=128M,bootable,id=0x0e; name=rootfs,size=3072M,id=0x83; name=system-data,size=512M,id=0x83; name=[ext],size=-,id=0x05; name=user,size=-,id=0x83; name=modules,size=100M,id=0x83; name=ramdisk,size=8M,id=0x83' > mbr write mmc 0 Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>

2020-10-28cmd: Add a mux commandPratyush Yadav
This command lets the user list, select, and deselect mux controllers introduced with the mux framework on the fly. It has 3 subcommands: list, select, and deselect. List: Lists all the mux present on the system. The muxes are listed for each chip. The chip is identified by its device name. Each chip can have a number of mux controllers. Each is listed in sequence and is assigned a sequential ID based on its position in the mux chip. It lists details like ID, whether the mux is currently selected or not, the current state, the idle state, and the number of states. A sample output would look something like: => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no unknown as-is 0x4 1 no 0x2 0x2 0x10 2 no 0x73 0x73 0x100 another-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x2 0x2 0x4 Select: Selects a given mux and puts it in the specified state. This subcommand takes 3 arguments: mux chip, mux ID, state to set the mux in. The arguments mux chip and mux ID are used to identify which mux needs to be selected, and then it is selected to the given state. The mux needs to be deselected before it can be selected again in another state. The state should be a hexadecimal number. For example: => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x1 0x1 0x4 => mux select a-mux-controller 0 0x3 => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 yes 0x3 0x1 0x4 1 no 0x1 0x1 0x4 Deselect: Deselects a given mux and puts it in its idle state. This subcommand takes 2 arguments: the mux chip and mux ID to identify which mux needs to be deselected. So in the above example, we can deselect mux 0 using: => mux deselect a-mux-controller 0 => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x1 0x1 0x4 Signed-off-by: Pratyush Yadav <p.yadav@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2019-07-11cmd: Add 'bcb' command to read/modify/write BCB fieldsEugeniu Rosca
'Bootloader Control Block' (BCB) is a well established term/acronym in the Android namespace which refers to a location in a dedicated raw (i.e. FS-unaware) flash (e.g. eMMC) partition, usually called "misc", which is used as media for exchanging messages between Android userspace (particularly recovery [1]) and an Android-capable bootloader. On higher level, this allows implementing a subset of Android Bootloader Requirements [2], amongst which is the Android-specific bootloader flow [3]. Regardless how the latter is implemented in U-Boot ([3] being the most memorable example), reading/writing/dumping the BCB fields in the development process from inside the U-Boot is a convenient feature.

Add a command to control the watchdog devices. This is useful if the watchdog is rather long running (eg. seconds) and it should be controlled by scripts. It is also handy during debugging. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: Stefan Roese <sr@denx.de>
2019-02-25cmd: add efidebug commandAKASHI Takahiro
Currently, there is no easy way to add or modify UEFI variables. In particular, bootmgr supports BootOrder/BootXXXX variables, it is quite hard to define them as u-boot variables because they are represented in a complicated and encoded format. The new command, efidebug, helps address these issues and give us more friendly interfaces: * efidebug boot add: add BootXXXX variable * efidebug boot rm: remove BootXXXX variable * efidebug boot dump: display all BootXXXX variables * efidebug boot next: set BootNext variable * efidebug boot order: set/display a boot order (BootOrder) Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
