9e9aa0b473 spl: fit: Only look up FIT configuration node once
The configuration node a sub node under "/configurations", which
describes the components to load from "/images". We only need to
locate this node once.

However, for each component, spl_fit_get_image_name() would parse the
FIT image, looking for the correct node. Such work duplication is not
necessary. Instead, once the node is found, cache it, and re-use it.

e4928270a4 spl: fit: Remove useless loop in spl_fit_get_image_name()
When a desired configuration is not found, conf_node will have a
negative value. Thus the for loop will start at the root "/" node of
the image, print the "/description" property, and stop.

It appears the intent of the loop was to print the names of the
subnodes under "/configurations". We would need the offset to the
"/configurations" node, which is abstracted by fit_find_config_node().

This change agrees that abstracting the node offset is the correct
design, and we shouldn't be parsing the configurations manually. Thus
the loop in spl_fit_get_image_name() is useless. Remove it.

3dc2079733 spl: fit: Pass FIT context via a structure pointer
Several loose arguments describe the FIT image. They are thus related,
and it makes sense to pass them together, in a structure. Examples
include the FIT blob pointer, offset to FDT nodes, and the offset to
external data.

Use a spl_fit_info structure to group these parameters.

917fa369f6 spl: fit: Factor out FIT parsing and use a context struct
The logical steps in spl_load_simple_fit() are difficult to follow.
I think the long comments, ifdefs, and ungodly number of variables
seriously affect the readability. In particular, it violates section 6
of the coding style, paragraphs (3), and (4).

The purpose of this patch is to improve the situation by
  - Factoring out initialization and parsing to separate functions
  - Reduce the number of variables by using a context structure
This change introduces no functional changes.

efc4ad0bc7 spl: fit: Drop 'length' argument to board_spl_fit_post_load()
The size is derived from the FIT image itself. Any alignment
requirements are machine-specific and known by the board code. Thus
the total length can be derived from the FIT image and knowledge of
the platform. The 'length' argument is redundant. Remove it.

eb5fd9e46c usb: kbd: destroy device after console is stopped
In case of IOMUX enabled it assumes that console devices in the list
are available to get them stopped properly via ->stop() callback.
However, the USB keyboard driver violates this assumption and tries
to play tricks so the device get destroyed while being listed as
an active console.

Swap the order of device deregistration and IOMUX update along with
converting to use iomux_replace_device() jelper to avoid the use-after-free.

In fit_config_verify_sig(), when no 'signature*' subnode exists in

Therefore, no error flags are set, and 'err_,sg' is not populated

Populate err_msg to indicate that no 'signature' is found, before
entering the loop. The first call to fit_image_verify_sig() will

1e993710e8 console: remove #ifdef CONFIG_CONSOLE_RECORD
Add helper functions to access to gd->console_out and gd->console_in
with membuff API and replace the #ifdef CONFIG_CONSOLE_RECORD test
by if (IS_ENABLED(CONFIG_CONSOLE_RECORD)) to respect the U-Boot
coding rule.
