[U-Boot] [BUG] efi_loader: SIMPLE_TEXT_INPUT_EX plus wire up objects properly

[Heinrich Schuchardt]

Hello Alex,

in your efi-next tree you have merged
efi_loader: SIMPLE_TEXT_INPUT_EX plus wire up objects properly
https://github.com/agraf/u-boot/commit/3486573794a0809d987fd690b1bf6c9093124ce9

The EFI_SIMPLE_TEXT_INPUT_PROTOCOL can be tested with:

setenv efi_selftest text input
bootefi selftest

Before the patch entering CTRL+C resulted in:

Executing 'text input'
Waiting for your input
To terminate type 'x'


Unicode char 3 (unknown), scan code 0 (Null)

With this patch CTRC+C is not interpreted as 0x03 anymore.

So, please, remove the patch from the repository, rework it and subject
it to review.

I will try to write a Python test for EFI_SIMPLE_TEXT_INPUT_PROTOCOL so
that we do not miss the problem again.

We need testing for the EFISIMPLE_TEXT_INPUT_EX_PROTOCOL too.

Best regards

Heinrich
