26839e5dde cmd: SCP03: enable and provision command
Enable and provision the SCP03 keys on a TEE controlled secured elemt
from the U-Boot shell.

Executing this command will generate and program new SCP03 encryption
keys on the secure element NVM.

Depending on the TEE implementation, the keys would then be stored in
some persistent storage or better derived from some platform secret
(so they can't be lost).

750c543ca7 cmd: Add MBR partition layout control utility
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;

05115abe8d cmd: Add a mux command
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

9744d1a547 cmd: Add command to display or save Linux PStore dumps
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

94f6d0d1bd cmd: abootimg: Add abootimg command
This command can be used to extract fields and image payloads from
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

Perform the rename in several steps:
 1. Rename *.c file and Kconfig symbol. This should allow

 2. 's/dtimg/adtimg/g' in the internal namespace of 'adtimg.c'

Add support for capturing ethernet packets and storing
them in memory in PCAP(2.4) format, later to be analyzed by
any PCAP viewer software (IE. Wireshark)

This feature greatly assist debugging network issues such
as detecting dropped packets, packet corruption etc.

17030c7c4c cmd: Add 'ab_select' command
For A/B system update support the Android boot process requires to send
'androidboot.slot_suffix' parameter as a command line argument. This
patch implementes 'ab_select' command which allows us to obtain current
slot by processing the A/B metadata.

The patch was extracted from commit [1] with one modification: the
separator for specifying the name of metadata partition was changed
from ';' to '#', because ';' is used for commands separation.

a897269c93 cmd: Remove mmc_spi command
The mmc_spi command was added to manually setup MMC over SPI bus
using command. This was required by the legacy non-DM MMC_SPI driver.

With DM based MMC_SPI driver in-place, we can now use all general
storge commands and mmc command for MMC over SPI bus hence we remove
the mmc_spi command all it's references.

db7b7a05b2 cmd: Add 'bcb' command to read/modify/write BCB fields
'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.
Hence, make it available to the users.

Some usage examples of the new command recorded on R-Car H3ULCB-KF
('>>>' is an overlay on top of the original console output):

=> bcb
bcb - Load/set/clear/test/dump/store Android BCB fields

Usage:
bcb load  <dev> <part>       - load  BCB from mmc <dev>:<part>
bcb set   <field> <val>      - set   BCB <field> to <val>
bcb clear [<field>]          - clear BCB <field> or all fields
bcb test  <field> <op> <val> - test  BCB <field> against <val>
bcb dump  <field>            - dump  BCB <field>
bcb store                    - store BCB back to mmc

Legend:
<dev>   - MMC device index containing the BCB partition
<part>  - MMC partition index or name containing the BCB
<field> - one of {command,status,recovery,stage,reserved}
<op>    - the binary operator used in 'bcb test':
          '=' returns true if <val> matches the string stored in <field>
          '~' returns true if <val> matches a subset of <field>'s string
<val>   - string/text provided as input to bcb {set,test}
          NOTE: any ':' character in <val> will be replaced by line feed
          during 'bcb set' and used as separator by upper layers

=> bcb dump command
Error: Please, load BCB first!
 >>> Users must specify mmc device and partition before any other call

=> bcb load 1 misc

59df7e7e77 cmd: add efidebug command
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)
