[U-Boot] Generic keyboard input handler

[Simon Glass]

Hi,

This is mostly directed at the input maintainer, who may be Wolfgang.

In discussions on the list regarding a new keyboard driver it has come
up that there is no generic way to translate key codes into ASCII
characters, nor to translate unshifted keys to shifted keys. The two
keyboard drivers I can see in U-Boot have their own code for doing
this.

Do we want such a layer in U-Boot, perhaps as an additional file in
drivers/input which does the translation and supports English and
German? It would be called by the two existing drivers and my newone.
I can't see something there already, but maybe it is hidden.

If so, I may look at it. If not, I will put some sort of translator in
the Tegra keyboard driver.

Regards,
Simon
