efi_loader: initialize console size late

2022-06-19T13:53:09+00:00

If CONFIG_VIDEO_DM=n we query the display size from the serial console.
Especially when using a remote console the response can be so late that
it interferes with autoboot.

Only query the console size when running an EFI binary.

Add debug output showing the determined console size.

efi_loader: reset colors before clearing screen

2022-05-03T19:39:22+00:00

When resetting the text console the colors have to be set before clearing
the screen. Otherwise the background color may be wrong.

efi_loader: add handle for UART

2022-02-05T19:20:01+00:00

When loading an EFI binary via the UART we assign a UART device path to it.
But we lack a handle with that device path.

efi_loader: NULL dereference in EFI console

2021-03-19T19:47:25+00:00

Even if CONFIG_DM_VIDEO=y and stdout="vidconsole", a video device may not
be available. Check the return values of the relevant functions.

If no video output device is available, assume that the serial console is
in use.

efi_loader: console size of vidconsole

2021-03-07T16:37:12+00:00

If stdout is 'vidconsole', we correctly set the console size.
If stdout is 'vidconsole,serial', the video console is ignored.

We should always evaluate the size of vidconsole if it is the primary
console.

efi_loader: typedef efi_string_t text output protocol

2021-01-13T01:38:01+00:00

We do not want to use typedefs in U-Boot.

Do not use efi_string_t in the EFI_TEXT_OUTPUT_PROTOCOL.

efi_loader: escape key handling

2020-12-29T01:09:04+00:00

Up to now the escape key was not correctly detected in UEFI applications.
We had to hit it twice for a single escape to be recognized.

Use a 10 ms delay to detect if we are dealing with the escape key or an
escape sequence.

common: rename getc() to getchar()

2020-10-22T13:54:53+00:00

The sandbox is built with the SDL2 library with invokes the X11 library
which in turn calls getc(). But getc() in glibc is defined as

    int getc(FILE *)

This does not match our definition.

    int getc(void)

The sandbox crashes when called with parameter -l.

Rename our library symbol getc() to getchar().
