Bootmenu requires an input device with arrows and enter key.
A common smartphone luckily has power, volume up/down buttons,
which may be used for controlling bootmenu.
To use driver, add 'button-kbd' to stdin.

This driver adds support for the keyboard on Apple Silicon laptops.
The controller for this keyboard sits on an SPI bus and uses an
Apple-specific HID over SPI protocol. The packets sent by this
controller for key presses and key releases are fairly simple and
are decoded directly by the code in this driver and converted into
standard Linux keycodes. The same controller handles the touchpad
found on these laptops.  Packets for touchpad events are simply
ignored.

Sphinx expects Return: and not @return to indicate a return value.

This driver uses the CONFIG namespace to set the chips internal CONFIG
namespace related bits.  However, CONFIG is reserved for the top-level
Kconfig based configuration system.  Use CFG as the namespace here
instead to avoid pollution.

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Chromebooks and the sandbox use a crosswire keyboard with function keys
FN1 - FN10. These keys are needed when running UEFI applications like GRUB
or the UEFI SCT.

Add support for these keys when translating from key codes to
ECMA-48 (or withdrawn ANSI 3.64) escape sequences.

All escape sequences start with 0x1b. So we should not repeat this
byte in the kbd_to_ansi364 table.

For testing use:

sandbox_defconfig + CONFIG_EFI_SELFTEST=y

$ ./u-boot -D -l

=> setenv efi_selftest extended text input
=> bootefi selftest
