Currently there are 3 different variants of read_id implementation:
1. opcode only. Found in GD5FxGQ4xF.
2. opcode + 1 addr byte. Found in GD5GxGQ4xA/E
3. opcode + 1 dummy byte. Found in other currently supported chips.
Original implementation was for variant 1 and let detect function
of chips with variant 2 and 3 to ignore the first byte. This isn't
robust:
1. For chips of variant 2, if SPI master doesn't keep MOSI low
during read, chip will get a random id offset, and the entire id
buffer will shift by that offset, causing detect failure.
2. For chips of variant 1, if it happens to get a devid that equals
to manufacture id of variant 2 or 3 chips, it'll get incorrectly
detected.
This patch reworks detect procedure to address problems above. New
logic do detection for all variants separatedly, in 1-2-3 order.
Since all current detect methods do exactly the same id matching
procedure, unify them into core.c and remove detect method from
manufacture_ops.

To quote the author:
So far expo only supports menus. These are quite flexible for various
kinds of settings, but cannot deal with free-form input, such as a
serial number or a machine name.
This series adds support for a textline object, which is a single line
of text. It has a maximum length and its value is stored within the expo
structure.
U-Boot already has a command-line editor which provides most of the
features needed by expo. But the code runs in its own loop and only
returns when the line is finished. This is not suitable for expo, which
must handle a keypress at a time, returning to its caller after each
one.
In order to use the CLI code, some significant refactoring is included
here. This mostly involves moving the internal loop of the CLI to a
separate function and recording its state in a struct, just as was done
for single keypresses some time back. A minor addition is support for
Ctrl-W to delete a word, since strangely this is currently only present
in the simple version.
The video-console system provides most of the features needed by
testline, but a few things are missing. This series provides:
- primitive cursor support so the user can see where he is typing
- saving and restoring of the text-entry context, so that expo can allow
the user to continue where he left off, including deleting previously
entered characters correctly (for Truetype)
- obtaining the nominal width of a string of n characters, so that a
suitable width can be chosen for the textline object
Note that no support is provided for clearing the cursor. This was
addressed in a previous series[1] which could perhaps be rebased. For
this implementation, the cursor is therefore not enabled for the normal
command line, only for expo.
Reading and writing textline objects is supported for FDT and
environment, but not for CMOS RAM, since it would likely use too much
RAM to store a string.
In terms of code size, the overall size increase is 180 bytes for
Thumb02 boards, 160 of whcih is the addition of Ctrl-W to delete a word.

At present cedit only supports menu keys. For textline objects we need
to insert normal ASCII characters.
We also need to handle backspace, which is ASCII 9.
In fact, expo does not make use of all the menu keys, so partition
them accordingly and update the logic to support normal ASCII
characters, too.

Add rudimentary support for displaying a cursor on a vidconsole. This
helps the user to see where text is being entered.
The implementation so far is very simple: the cursor is just a vertical
bar of fixed width and cannot be erased. To erase the cursor, the text
must be redrawn over it.
This is good enough for expo but will need enhancement to be useful for
the command-line console. For example, it could save and restore the
area behind the cursor.
For now, enable this only for expo, to reduce code size.

At present this is called only when a newline is detected, since this

Signed-off-by: Simon Glass <sjg@chromium.org>
Text entry operates within a context which includes quite a bit of
information. For example, with Truetype fonts, each character in the
text string has a position stored, so that it is possible to
backspace to that character. This information is built up as strings
are drawn on the display.
For the command line, there is just a single context. It is created
when command-line entry starts and it is destroyed (or at least not
needed anymore) when the user presses <enter> to enter the command.
By contrast, expo needs to be able to switch in and out of a text-entry
context, since it is also displaying other objects in the scene.
Add a way to save and restore the entry context for a vidconsole. This
is only needed for the truetype vidconsole, so add a method for that,
storing the information in an abuf struct.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present there is a method for measuring text, but if the actual text
string is not known, it cannot be used.
For text editor we want to set the size of the entry box to cover the
expected text size. Add the concept of a 'norminal' size with a method
to calculate that for the vidconsole.
If the method is not implemented, fall back to using the font size,
which is sufficient for fixed-width fonts.
