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.

video: consolidate splash screen alignment code

2013-07-08T18:21:24+00:00

Code for checking "splashpos" environment variable is
duplicated in drivers, move it to the common function.
Call this function also in the bmp display command to
consider "splashpos" settings.

lcd: remove unaligned access in lcd_dt_simplefb_configure_node()

2013-07-01T18:11:33+00:00

Some ARM compilers may emit code that makes unaligned accesses when
faced with constructs such as:

const char format[] = "r5g6b5";

Make this data static since it doesn't chagne; the compiler will simply
place it into the .rodata section directly, and avoid any unaligned run-
time initialization.

lcd: add functions to set up simplefb device tree

2013-06-05T20:40:03+00:00

simple-framebuffer is a new device tree binding that describes a pre-
configured frame-buffer memory region and its format. The Linux kernel
contains a driver that supports this binding. Implement functions to
create a DT node (or fill in an existing node) with parameters that
describe the framebuffer format that U-Boot is using.

This will be immediately used by the Raspberry Pi board in U-Boot, and
likely will be used by the Samsung ARM ChromeBook support soon too. It
could well be used by many other boards (e.g. Tegra boards with built-in
LCD panels, which aren't yet supported by the Linux kernel).
