common/lcd_console: fix console/logo regression

2015-08-13T11:19:34+00:00

The following commit changed the order of the column vs. row parameter
to the lcd_init_console() function but missed actually changing it as
well the second time it is called from lcd_clear() which resulted in a
garbled text console which this patch fixes.

lcd: Support colour lookup table on 16bpp display in BMP images

2015-06-11T01:26:55+00:00

For 16-bit-per-pixel displays it is useful to support 8 bit-per-pixel
images to reduce image size. Add support for this when drawing BMP images.

Remove typedefs from bmp_layout.h

2015-06-11T01:26:54+00:00

We try to avoid typedefs and these ones are easy enough to remove. Before
changing this header in the next patch, remove the typedefs.

common: Make sure arch-specific map_sysmem() is defined

2015-04-18T17:11:09+00:00

In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.

Also split the non-arch specific functions out of common.h

common/lcd_console: introduce display/framebuffer rotation

2015-04-18T15:40:37+00:00

Sometimes, for example if the display is mounted in portrait mode or even if it
is mounted landscape but rotated by 180 degrees, we need to rotate our content
of the display respectively the framebuffer, so that user can read the messages
which are printed out.

For this we introduce the feature called "CONFIG_LCD_ROTATION", this may be
defined in the board-configuration if needed. After this the lcd_console will
be initialized with a given rotation from "vl_rot" out of "vidinfo_t" which is
provided by the board specific code.

If CONFIG_LCD_ROTATION is not defined, the console will be initialized with
0 degrees rotation.

lcd: split splash code into its own function

2015-02-10T12:31:58+00:00

lcd_logo() currently performs tasks well beyond just displaying the logo.
It has code which displays splash image, it has logic which determines
when the different display features are displayed, and it is coupled with
the lcd console because it holds the responsibility of returning the
lcd console base address.

Make lcd_logo() just about the logo by:
* Moving splash image display code into a dedicated function
* Moving the logic regarding when various features are displayed to
  lcd_clear() (which is arguably not the correct name for housing such
  code either, but it is currently the most fitting location code wise)
* Move the responsibility of setting the console base address to
  lcd_clear() too.

lcd: dt: extract simplefb support

2015-02-10T12:31:26+00:00

We now have api functions that can support compiling simplefb code as its own
module. Since this code is not part of the display functionality, extract it
to its own file.

Raspberry Pi is updated to accommodate the changes.

lcd: rename bitmap_plot to better represent its functionality

2015-02-10T12:30:49+00:00

The name "bitmap_plot" is misleading because it implies that this is a generic
function capable of dealing with any bitmap, but its implementation only works
with the logo data.

Rename the function to better reflect this.

lcd: various cleanups

This cleanup mostly focuses on removing unnecessary whitespace and comments
which are superfluous and/or do not conform to the coding style.
