efi_loader: escape key handling

2020-12-29T01:09:04Z

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. Signed-off-by: Heinrich Schuchardt

common: rename getc() to getchar()

2020-10-22T13:54:53Z

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().

efi_loader: comments EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL

Provide missing comments for the functions implementing the EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL. Signed-off-by: Heinrich Schuchardt

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

2020-02-06T02:33:46Z

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

2020-01-07T17:08:20Z

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. Signed-off-by: Heinrich Schuchardt

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

2019-12-02T23:23:13Z

This function belongs in time.h so move it over and add a comment. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

efi_loader: cursor positioning

2019-09-05T21:18:51Z

When backspacing in column 0 do no set the column index to ULONG_MAX. Ensure that the row number is not set to ULONG_MAX even if the row count is advertised as 0. Ignore control characters other the 0x08, 0x0a, 0x0d when updating the column. Signed-off-by: Heinrich Schuchardt
