lcd: restore ability to display 8 bpp BMPs on 16 bpp LCDs

2013-01-14T19:16:45+00:00

Commit fb6a9aab7ae78c (LCD: display 32bpp decompressed bitmap image)
broke the check that allowed U-Boot to display 8 bpp BMPs on a 16
bpp LCD screen, effectively turning this feature off.

Restore this feature by changing the check back to the same meaning
it originally had.
To avoid future confusion, the check has also been rephrased to make
its meaning clear.

lcd: Add CONFIG_CONSOLE_SCROLL_LINES option to speed console

2012-11-19T15:15:40+00:00

When the cursor position gets to the end of the LCD console we normally
scroll by one line. This adds an option to increase that value.

Console scrolling is often slow, and if a large amount of output is
being sent, increasing this option to 10 or so will speed things up
considerably.

lcd: Add CONFIG_LCD_ALIGNMENT to select frame buffer alignment

2012-11-19T15:15:38+00:00

The normal alignment is PAGE_SIZE, but if this is defined, we can support
other alignments.

The motivation for this change is to make the display section-aligned on
ARM so that we can easily turn off data caching for the frame buffer region
without resorting to level 2 page tables.

lcd: Fix BMP decode bug that skips the wrong padded row

2012-11-06T23:57:22+00:00

This change fixed 2 things:
 - Rename padded_line to padded_width since it is (width + padded_row) not line.
 - When finished a line, should skip the padded_row that is
   (padded_width - width) instead of (width - padded_width).

lcd: Provide an API to access LCD parameters

2012-11-06T23:57:16+00:00

Create a basic API to provide access to lcd parameters such as screen
size, and to position the cursor on the screen.

This matches up with the video API for the same purpose. Unfortunately
they are not yet combined.

common/lcd: add protection from null bmp pointer

2012-09-21T21:41:56+00:00

If the bmp pointer is null then U-Boot will get stuck when trying
to load the image.
What's worse, it will get stuck before the U-Boot shell becomes
available to the user, thus making it difficult to correct the
situation.

To protect from the above scenario, check if the pointer is valid.
