video: bcm2835: fix build issues

2013-03-29T13:29:39+00:00

After merging LCD patches for v2013.04 the bcm2835 video
driver building is broken due to removal of many global
variables. Fix the driver.

Fix bitmap offsets for non 8-bit LCDs

2013-03-21T09:50:42+00:00

Currently bitmap logos don't interpret the X coordinate
correctly if the bpp is anything other than 8.

Hide the console macros since some reference global data which is
no longer present.

common/lcd.c: remove global lcd_base

2013-03-21T09:16:53+00:00

lcd_base is available as gd->fb_base as well, there is no need
to keep a seperate copy.

For completeness the ack of Bo Shen is for the atmel part.

common/lcd.c: cleanup use of global variables

2013-03-21T09:11:17+00:00

console_col, console_row, lcd_line_length, lcd_console_address had
to be declared in board / driver specific code, but were not actually
used there on many boards. Get rid of the global variables.

common/lcd.c: cleanup use of global variables

2013-03-21T08:05:08+00:00

lcd_color_fg and lcd_color_bg had to be declared in board specific
code, but were not actually used there; in addition, we have getter /
setter functions for these, which were not used either.

Get rid of the global variables, and use the getter function where
needed (so far no setter calls are needed).

lcd: calculate line_length after lcd_ctrl_init()

2013-03-20T14:29:39+00:00

When an LCD driver is actually driving a regular external display, e.g.
an HDMI monitor, the display resolution might not be known until the
display controller has initialized, i.e. during lcd_ctrl_init(). However,
lcd.c calculates lcd_line_length before calling this function, thus
relying on a hard-coded resolution in struct panel_info.

Instead, defer this calculation until after lcd_ctrl_init() has had the
chance to dynamically determine the resolution. This needs to happen
before lcd_clear(), since the value is used there.

grep indicates that no code outside lcd.c uses this lcd_line_length; in
particular, no lcd_ctrl_init() implementations read it.

lcd: implement a callback for splashimage

2013-03-11T15:06:09+00:00

On some architectures certain values of splashimage will lead to
a data abort exception.

Document the problem, and implement a callback for splashimage to
reject such values.
