cfb_console: fix RLE bitmap drawing code

2011-04-28T19:30:46+00:00

There seems to be tools producing incorrect 'end of bitmap data'
markers '0100' in a RLE bitmap. Drawing such bitmaps can result
in overwriting memory above the frame buffer. E.g. on MPC5121e
based boards this memory can contain U-Boot environment.

We may not rely on the correct end of bitmap data marker 0001
only, but also have to check whether we are going to draw a
valid frame buffer scan line.

The patch provides a fix by maintaining a pixel counter
which is incremented by the amount of pixels we are going
to draw. If the counter exceeds frame buffer pixels limit
we stop the drawing with the error message.

video: cfb_console: fix definition and usage of CURSOR_xxx macros

2010-09-15T22:44:06+00:00

The CURSOR_ON, CURSOR_OFF, and CURSOR_SET macros are defined incorrectly.  If
cursor support is disabled, then these macros are defined to nothing, but
then they are used like this:

	if (console_col < CONSOLE_COLS)
		CURSOR_OFF
	console_row++;

which was compiled like this:

	if (console_col < CONSOLE_COLS)
		console_row++;

This is obviously not what was intended.

video: cfb_console: add weak default video_set_lut()

2010-06-14T10:28:28+00:00

Do not enforce drivers to provide empty video_set_lut()
if they do not implement indexed color (8 bpp) frame
buffer support. Add default function to the cfb_console
driver and remove empty video_set_lut() functions.

video: Fix console display when splashscreen is used

2010-03-13T15:42:25+00:00

If a splashscreen is used the console scrolling used the
scroll size as needed when a logo was displayed. This
patch sets the scroll size to the whole screen if
a splashscreen is shown.

move prototypes for gunzip() and zunzip() to common.h

2009-12-21T20:39:59+00:00

Prototype for gunzip/zunzip was only in lib_generic/gunzip.c and thus
repeated in every file using it. This patch moves the prototypes to
common.h and removes all prototypes distributed anywhere else.

video: mb862xx: add option VIDEO_FB_16BPP_WORD_SWAP for IPEK01

2009-10-31T11:17:40+00:00

In 16 bpp mode, the new IPEK01 board only requires swapping of D16 words
for D32 accesses due to the diffferent connecting to the GDC bus. This
patch introduces the configuration option VIDEO_FB_16BPP_WORD_SWAP,
which should be set for all board using the mb862xx in 16 bpp mode. For
the IPEK01, VIDEO_FB_16BPP_PIXEL_SWAP should not be set.
