video: Drop unnecessary #ifdef around vid_console_color()

2020-07-09T04:33:24+00:00

All of the functions in this file only apply if DM_VIDEO is enabled. Drop
the #ifdef as it just clutters things up. Add the needed forward
declaration.

dm: video: support more escape sequences

2018-09-28T16:25:39+00:00

The EFI subsystems needs to know the size of the terminal. If the
environment variable

	stdout = serial,vidconsole

this size cannot be read from the video console. So the EFI subsystem
sends escape sequences to read the size. With this patch we get support
for the following escape sequences:

ESC "7"		Save cursor position
ESC "8"		Restore cursor position

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

dm: video: Add basic ANSI escape sequence support

2017-09-29T15:53:21+00:00

Really just the subset that is needed by efi_console.  Perhaps more will
be added later, for example color support would be useful to implement
efi_cout_set_attribute().

video: Provide a backspace method

2016-01-30T09:55:37+00:00

With proportional fonts the vidconsole uclass cannot itself erase the
previous character. Provide an optional method so that the driver can
handle this operation.
