Linux/AM3351: Splash screen in U-boot

thanks Biser,
1. i am trying to add this patch in u-boot-2017.01.
   but i din't have "arch/arm/cpu/armv7/am33xx/clock_am33xx.c"

so  i added &cmper->lcdclkctrl, &cmper->lcdcclkstctrl
to u32 *const clk_modules_explicit_en[] in arch/arm/mach-omap2/am33xx/clock_am33xx.c 

2.i am getting below error:

common/lcd_console.c: In function 'console_newline':
common/lcd_console.c:106:19: error: 'CONFIG_CONSOLE_SCROLL_LINES' undeclared (first use in this function)
const int rows = CONFIG_CONSOLE_SCROLL_LINES;
^~~~~~~~~~~~~~~~~~~~~~~~~~~

added #define CONFIG_CONSOLE_SCROLL_LINES 10 in am335x_evm.h

3.error:

./scripts/check-config.sh u-boot.cfg \
./scripts/config_whitelist.txt . 1>&2
Error: You must add new CONFIG options using Kconfig
The following new ad-hoc CONFIG options were detected:
CONFIG_SPLASH

Please add these via Kconfig instead. Find a suitable Kconfig
file and add a 'config' or 'menuconfig' option.

added CONFIG_SPLASH /scripts/config_whitelist.txt

4. i am using TMDXEVM3358-SK-LCD board and 480x272 16 bpp splash image. but image is displaying like below.
