Peter A. Bigot 1090dbc6b4 subsys/cfb: improve font structure packing
The specified order of fields wastes space when the cfb_font_caps enum
isn't packed.  Reorder to avoid this behavior.

Also remove the unnecessary array size on the extern symbol declaration,
lest the compiler misinterpret the properties as being zero-length
arrays rather than pointers.  (The idiom is already technically
using undefined behavior since we're relying on the linker rather than
the language to produce an array from the individual declarations.)

Peter A. Bigot a66a036a8f subsys/cfb: correct font definition macro for linker script
This macro provides the required alignment directives to ensure that the
font definitions are placed properly for iteration as members of an
array object.

Charles E. Youse 4c63e29aec arch/x86: drivers/display: add framebuffer driver w/ multiboot support
A basic display driver is added for a generic 32-bpp framebuffer.
Glue logic is added to the x86 arch to request the intitialization
of a linear framebuffer by the Multiboot loader (GRUB) and connect
it to this generic driver.

Johann Fischer f531e0d62e subsys: add monochrome character framebuffer
Add monochrome character framebuffer for monochrome
graphic dot matrix displays and electrophoretic displays.

These displays are mostly monochrome and can only display
black and some other color, for example white. Typically,
a byte controls 8 pixels, arranged vertically or horizontally
depending on the controller or settings.
The API is not suitable to display graphics, the purpose is
to display text or symbols. It is possible to use several fonts.
A font can also consist of graphic symbols only and thus,
for example, enable the realization of a menu.

Kumar Gala cc334c7273 Convert remaining code to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  This handles the remaining includes and kernel, plus
touching up various points that we skipped because of include
dependancies.  We also convert the PRI printf formatters in the arch
code over to normal formatters.

Kumar Gala 789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Johan Hedberg d7a189d2ec drivers: display: mb_display: Unify image and string APIs
Both the string and image rendering may want to take advantage of
scrolling and sequential display capabilities. Consolidate the APIs so
that there's a single one for images (mb_display_image) and a single
one for strings (mb_display_print). Both take a duration parameter for
the per-frame duration as well as a mode parameter which specifies
sequential vs scrolling behavior as well as an optional looping flag.

Add a new mb_display_print() API which takes printf-style parameters
and outputs scrolling text instead of one character at a time. The
existing mb_display_str() API is renamed to mb_display_string() for

Johan Hedberg 380d24de1d drivers: Add support for BBC micro:bit LED display
Adds a simple driver to access the 5x5 LED display found on BBC
micro:bit boards. The display is so limited that no effort is done to
try to integrate with the existing console (which would likely make
the display unusable). Instead, dedicated mb_display_* APIs are added
that are specific to this display.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.
