2013-03-11ARM: OMAP4+: Cleanup the clocks layerSRICHARAN R
Currently there is quite a lot of code which is duplicated in the clocks code for OMAP 4 and 5 Socs. Avoiding this here by moving the clocks data to a SOC specific place and the sharing the common code. This helps in addition of a new Soc with minimal changes.

2013-03-11ARM: OMAP4+: Change the PRCM structure prototype common for all SocsSRICHARAN R
The current PRCM structure prototype directly matches the hardware register layout. So there is a need to change this for every new silicon revision which has register space changes. Avoiding this by making the prototye generic and populating the register addresses seperately for all Socs.

2013-03-11ARM: OMAP4+: emif: Detect SDRAM from SDRAM config registerLokesh Vutla
Now SDRAM initialization is done on the basis of omap revision. Instead this should be done on basis of SDRAM type read from EMIF_SDRAM_CONFIG register. This will be helpful to avoid unnessecary cpu checks for new boards Signed-off-by: R Sricharan <r.sricharan@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tom Rini <trini@ti.com>

Before submitting packets to cpdma, phy status is updated on every packet which leads to delay in packet send intern reduces the Ethernet performance. Checking mdio status for each packet will reduce timetaken to send a packet and there by increasing the Ethernet performance.

2013-03-08lcd: add option for board specific splash screen preparationNikita Kiryanov
Currently there is no logical place to put the code that prepares the splash image data. The splash image data should be ready in memory before bmp_display() is called, and after the environment is ready (since lcd.c looks for the splash image in an address specified by the environment variable "splashimage"). Our window of opportunity in board_init_r() is therefore: between env_relocate() and bmp_display(), and from the available options only the lcd related functions in drv_lcd_init() seem appropriate for such lcd oriented code. Add the option to prepare the splash image data in lcd_logo() right before it is sent to be displayed.

2013-03-08omap3: allow dynamic selection of gfx_formatNikita Kiryanov
Currently, omap3_dss_panel_config() sets gfx_format to a value that is hardcoded in the code. This forces anyone who wants to use a different gfx_format to make adjustments after calling omap3_dss_panel_config(). This could be avoided if the value of gfx_format were parameterized as input for omap3_dss_panel_config(). Make gfx_format a field in struct panel_config, and update existing structs to set this field to the value that was originally hard coded.
