* efi_loader: NULL dereference in EFI consoleHeinrich Schuchardt2021-03-191-13/+38
| | | | | | | | | | 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. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
* efi_loader: console size of vidconsoleHeinrich Schuchardt2021-03-071-1/+1
| | | | | | | | | | 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. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
* efi_loader: typedef efi_string_t text output protocolHeinrich Schuchardt2021-01-131-3/+3
| | | | | | | | We do not want to use typedefs in U-Boot. Do not use efi_string_t in the EFI_TEXT_OUTPUT_PROTOCOL. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
* efi_loader: escape key handlingHeinrich Schuchardt2020-12-291-0/+12
| | | | | | | | | | 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 <xypron.glpk@gmx.de>
* common: rename getc() to getchar()Heinrich Schuchardt2020-10-221-10/+10
| | | | | | | | | | | | | | | | | | | 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' featuresSimon Glass2020-02-051-0/+1
| | | | | | | | | | | | 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 homeHeinrich Schuchardt2020-01-071-1/+15
| | | | | | | | | | | On a VT100 terminal <ESC>[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 <ESC>[H. For reference see the console_codes(4) man page. Add a function description. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

* efi_loader: Fix serial console size detectionMatthias Brugger2019-03-101-27/+35
| | | | | | | | | | | | | | | | | | | Function term_read_reply tries to read from the serial console until the end_char was read. This can hang forever if we are, for some reason, not able to read the full response (e.g. serial buffer too small, frame error).

| | | | | | | | | | | | | Not all terminals understand CSI [18t for querying the console size. We should adhere to escape sequences documented in the console_codes manpage and the ECMA-48 standard.
