Currently, there is no way for users to check the readings from thermal
sensors from U-boot console, only some boards print it during boot.
So, lets add a simple "temperature" command that allows listing thermal
uclass devices and getting their value.
Note that the thermal devices are intenionally probed if list is used as
almost always they will not get probed otherwise and there is no way for
users to manually call probe on a certain device from console.
Assumption is made that temperature is returned in degrees C and not
milidegrees like in Linux as this is what most drivers seem to return.

This commit add the "eficonfig" command.
The "eficonfig" command implements the menu-driven UEFI boot option
maintenance feature. This commit implements the addition of
new boot option. User can select the block device volume having
efi_simple_file_system_protocol and select the file corresponding
to the Boot#### variable. User can also enter the description and
optional_data of the BOOT#### variable in utf8.
This commit adds "include/efi_config.h", it contains the common
definition to be used from other menus such as UEFI Secure Boot
key management.

This patch adds the cyclic command, which currently only supports the
'list' subcommand, to list all currently registered cyclic functions.
Here an example:
=> cyclic list
function: cyclic_demo, cpu-time: 7010 us, frequency: 99.80 times/s
function: cyclic_demo2, cpu-time: 1 us, frequency: 1.13 times/s
As you can see, the cpu-time is accounted, so that cyclic functions
that take too long might be discovered. Additionally the frequency is
logged.
The 'cyclic demo' commands registers the cyclic_demo() function to
be executed all 'cycletime_ms' milliseconds. The only thing this
function does is delaying by 'delay_us' microseconds.

This command is being introduced with the goal of allowing user-friendly
"generic use case" U-Boot builds to pause until user input under some
situations.
The main use case would be when a boot failure happens, to pause until
the user has had time to acknowledge the current state.
Tested using:
make && ./u-boot -v -T -c 'ut lib lib_test_hush_pause'

Tested on a Rockchip PX30 (Odroid Go Advance), you must have loaded
the devicetree first and prepared it for editing. On my device the

setenv dtb_loadaddr "0x01f00000"
load mmc 0:1 ${dtb_loadaddr} rk3326-odroid-go2.dtb
fdt addr ${dtb_loadaddr}
fdt resize

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

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

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

This patch adds a new pstore command allowing to display or save ramoops
logs (oops, panic, console, ftrace and user) generated by a previous
kernel crash.
PStore parameters can be set in U-Boot configuration file, or at run-time
using "pstore set" command. Records size should be the same as the ones
used by kernel, and should be a power of 2.
This command allows:
- to display uncompressed logs
- to save compressed or uncompressed logs, compressed logs are saved as a
compressed stream, it may need some work to be able to decompress it,
e.g. adding a fake header:
"printf "\x1f\x8b\x08\x00\x00\x00\x00\x00\x00\x00" |
cat - dmesg-ramoops-0.enc.z | gzip -dc"
- ECC part is not used to check memory corruption
- only 1st FTrace log is displayed or saved

Android Boot Image. It can be used for example to implement boot flow
where dtb is taken from boot.img (as v2 incorporated dtb inside of
boot.img). Using this command, one can obtain needed dtb blob from
boot.img in scripting manner, and then apply needed dtbo's (from "dtbo"
partition) on top of that, providing then the resulting image to bootm
command in order to boot the Android.
Also right now this command has the sub-command to get an address and
size of recovery dtbo from recovery image (for non-A/B devices only,
see [1,2] for details).
It can be tested like this:
=> mmc dev 1
=> part start mmc 1 boot_a boot_start
=> part size mmc 1 boot_a boot_size
=> mmc read $loadaddr $boot_start $boot_size
=> abootimg get ver
=> abootimg dump dtb
