video: Support a cursor more generally
At present U-Boot does not support displaying a cursor on the console,
except with expo.
It is quite useful to have a cursor, particularly when using the
command-line editor.
This series adds tracking of the cursor position for both truetype and
normal consoles. The cursor is shown when U-Boot is idle and is removed
before writing characters to the display. A save-buffer ensures that the
old display contents are provided.
Some related improvements in this series include:
- expo lineedit support with normal console
- arrow keys now render correctly when editing commands with truetype
- truetype console now also supports bitmap fonts
The cursor is not currently supported for rotated consoles.
A README for claude is provided, although so far I have not had too much
success with it.
A fix for an intermittent build is added as well, along with silencing
some build messages noticed from Rust ulib.
