lcd: support displaying 24bpp BMPs on >= 24bpp LCDs

2014-08-11T16:07:09+00:00

most todays LCDs support 32bpp e.g. the framebuffer memory is 32bpp
organized.

To support 24bpp BMPs we need to take only 3 byte from the bpp and set
one byte from the FB to 0.

lcd: cleanup unused functions

2014-08-10T13:25:19+00:00

This patch removes following two functions:
- lcd_getbgcolor(...)
  not used somewhere outside lcd.c, internally we use now the global
  variable lcd_color_bg (was return value of function before)
- lcd_getfgcolor(...)
  not used in any place of u-boot

stdio: Pass device pointer to stdio methods

2014-07-23T13:07:23+00:00

At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.

For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.

Instead, add a stdio_dev pointer to each of the stdio member functions.

Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.

Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

sandbox: Add LCD driver

2014-03-18T02:05:49+00:00

Add a simple LCD driver which uses SDL to display the image. We update the
image regularly, while still providing for reasonable performance.

Adjust the common lcd code to support sandbox.

For command-line runs we do not want the LCD to be displayed, so add a
--show_lcd option to enable it.

common: lcd.c: fix data abort exception when try to access bmp header

2014-02-03T06:36:14+00:00

Changes:
- le16_to_cpu() to get_unaligned_le16()
- le32_to_cpu() to get_unaligned_le32()
when access fields in struct bmp header.

This changes avoids data abort exception caused by unaligned data access.

lcd: allow overriding lcd_get_size()

2013-11-12T08:35:17+00:00

Remove the redundant lcd_line_length initialisation which
sneaked in when an earlier version of the patch of commit
6d330719 has been rebased.

Some lcd drivers need to setup lcd_line_length not from the
panel_info parameters but by different means. Make the
lcd_get_size() weak to allow setting lcd_line_length in
a driver specific way.

video: Encapsulate font in video_font_data.h

2013-08-12T20:28:41+00:00

This patch moves all the font configuration values into video_font_data.h
so they are all in the right place with the font. The video_font.h now only
includes video_font_data.h and will allow us to select and include different
font once more fonts are added.
