We need to access reg stp_rep9, but not stp_rep[(9 - 1) / 2]. If using "__raw_writel(0, DI_STP_REP(disp, 9))", this will exceeds the size of stp_rep array.

2015-11-20video: Drop unused console functionsSimon Glass
CONFIG_CONSOLE_CURSOR, CONFIG_SYS_CONSOLE_BLINK_COUNT and CONFIG_CONSOLE_TIME are not used by any board. The implementation is not great and stands in the way of a refactor of i8042. Drop these for now. They can be re-introduced quite easily later, perhaps with driver-model real-time-clock (RTC) support. When reintroducing, it might be useful to make a few changes: - Blink time would be more useful than blink count - The confusing #ifdefs should be avoided - The time functions should support driver model - It would be best keyed off console_tstc() or some similar idle loop rather than a particular input driver (i8042 in this case) Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-11-12video: mxsfb: introduce lcdif_power_downPeng Fan
Introudce a new function lcdif_power_down. 1. Waits for a VSYNC interrupt to guarantee the reset is done at the VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?) and helps the LCDIF work normally at the kernel stage. 2. Add power down function to stop lcdif. The reason to introduce lcdif_power_down is that we want lcdif to be in initial state when doing uboot reset or before kernel boot to make system stable, otherwise system may hang.

2015-08-26video: cfb_console: Allow VGA device to work without i8042 keyboardBin Meng
So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device will try to initialize a keyboard device (for x86, it is i8042). But if i8042 controller initialization fails (eg: there is no keyboard connected to the PS/2 port), drv_video_init() just simply returns. This kills the opportunity of using a usb keyboard later with the vga console, as the vga initialization part is actually ok, only keyboard part fails. Change the code logic to allow this.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.

It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.
