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().

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

efi_loader: clear screen should move cursor to home

2020-01-07T17:08:20+00:00

On a VT100 terminal [2J should be enough to both clear the whole
screen and set the cursor to position (1, 1). But the Linux console does
not behave like this. So send an extra [H. For reference see the
console_codes(4) man page.

Add a function description.

common: Move get_ticks() function out of common.h

2019-12-02T23:23:13+00:00

This function belongs in time.h so move it over and add a comment.
