2015-04-18common/lcd_console: introduce display/framebuffer rotationHannes Petermaier
Sometimes, for example if the display is mounted in portrait mode or even if it is mounted landscape but rotated by 180 degrees, we need to rotate our content of the display respectively the framebuffer, so that user can read the messages which are printed out. For this we introduce the feature called "CONFIG_LCD_ROTATION", this may be defined in the board-configuration if needed. After this the lcd_console will be initialized with a given rotation from "vl_rot" out of "vidinfo_t" which is provided by the board specific code. If CONFIG_LCD_ROTATION is not defined, the console will be initialized with 0 degrees rotation.

2015-04-18common/lcd_console: move single static variables into common (static) structureHannes Petermaier
For coming implementation of lcd_console rotation, we will need some more variables for holding information about framebuffer size, rotation, ... For better readability we catch all them into a common structure.

2015-04-18common/lcd_console: ask only one-time for bg/fg-color per callHannes Petermaier
Don't call the lcd_getfgcolor and lcd_getbgcolor within the "draw-loop", this only wastes time. Signed-off-by: Hannes Petermaier <hannes.petermaier@br-automation.com> Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at> Acked-by: Nikita Kiryanov <nikita@compulab.co.il>
2015-04-18common/lcd_console: cleanup lcd_drawchars/lcd_putc_xyHannes Petermaier
the capability of drawing some *str with count from lcd_drawchars is unnary. It is always called from lcd_putc_xy with one character of and count = 1. So we simply rename lcd_drawchars into lcd_putc_xy and remove the loops inside.

2015-03-06common/lcd: Add command for writing to lcd-displayHannes Petermaier
Sometimes we do not want redirect u-boot's console to screen but anyway we want write out some status information out of a u-boot script to the display. So we cannot use the normal "echo ....", instead we write explicitly using "lcdputs ..." for writing to the actual cursor position on LCD. Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at>
2015-03-06common/lcd: Add command for setting cursor within lcd-consoleHannes Petermaier
Sometimes we do not want redirect u-boot's console to screen but anyway we want write out some status information out of a u-boot script to the display. To define the specific position of the string to be written, we have to set the cursor with "setcurs" before writing. Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at>

2015-01-10lcd: refactor lcd console stuff into its own fileNikita Kiryanov
common/lcd.c is a mix of code portions that do different but related things. To improve modularity, the various code portions should be split into their own modules. Separate lcd console code into its own file.
