ad80a8d087 cmd: disk: Remove fit_print_contents API
fit_print_contents prints similar fit information as printed in bootm stages.
Removing this API reduces redundancy & provides improvement in boottime.

83a287a613 bootmenu: Allow to quit it via ESC/CTRL+C
When ESC/CTRL+C is pressed interrupt bootmenu and jump into U-Boot console.
As the last entry in bootmenu is always U-Boot console just choose the last
entry when ESC or CTRL+C is pressed.

ESC key is detected when either no other character appears after '\e'
within 10ms or when non-'[' appears after '\e'.

It is useful when bootmenu is part of boot process and you want to
interrupt boot process by scripts which control U-Boot (serial) console.

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;
  name=[ext],size=-,id=0x05;
  name=user,size=-,id=0x83;

5f59518a7b efi_loader: setting boot device
Up to now the bootefi command used the last file loaded to determine the
boot partition. This has led to errors when the fdt had been loaded from

9528229f22 setexpr: Correct dropping of final unmatched string
At present the 'nlen' variable increases with each loop. If the previous
loop had back references, then subsequent loops without back references
use the wrong value of nlen. The value is larger, meaning that the string
terminator from nbuf is copied along to the main buffer, thus terminating
the string prematurely.

This leads to the final result being truncated, e.g. missing the last
(unmatched) part of the string. So "match match tail" become
"replaced replaced" instead of "replaced replaced tail".

Fix this by resetting nlen to the correct value each time around the lop.

At present this function assumes that a size of 4 refers to a ulong. This
is true on 32-bit machines but not commonly on 64-bit machines.

This means that the 'l' specify does not work correctly with setexpr.

Add an explicit case for 32-bit values so that 64-bit machines can still
use the 'l' specifier. On 32-bit machines, 64-bit is still not supported.

This corrects the operation of the default size (which is 4 for setexpr),
so update the tests accordingly.

The original code for reading from memory was included in 47ab5ad145

a Fixes: tag since that code was not written with 64-bit machines in mind.

also adds support for using log level names instead of just the integer
equivalent.

62ef81891d test: log: Convert log_test from python to C
When rebasing this series I had to renumber all my log tests because
someone made another log test in the meantime. This involved updaing a
number in several places (C and python), and it wasn't checked by the
compiler. So I though "how hard could it be to just rewrite in C?" And
though it wasn't hard, it *was* tedious. Tests are numbered the same as
before to allow for easier review.

A note that if a test fails, everything after it will probably also fail.
This is because that test won't clean up its filters.  There's no easy way
to do the cleanup, except perhaps removing all filters in a wrapper
function.

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
