Logo is displayed by Linux kernel:

Kernel configuration
You can manage the video support through the following kernel configuration options:

MXS LCD framebuffer support (CONFIG_FB_MXS)
Support for frame buffer devices (CONFIG_FB)
Low-level LCD controls (LCD_CLASS_DEVICE)
Platform LCD controls (LCD_PLATFORM)
Show the logo centered in the screen (FB_LOGO_CENTERED)
Custom logo 224-color (displays logo_custom_clut224.ppm) (LOGO_CUSTOM_CLUT224)
MXC PxP V4L2 driver (CONFIG_VIDEO_MXC_PXP_V4L2)

The Logo can be found in the bitbake build directory under "tmp/work-shared/ccimx6sbc/kernel-source/drivers/video/logo/logo_custom_clut224.ppm"

Replace the image there with your own pic. I used netpbm to convert a png to ppm:

$ sudo apt-get install netpbm
$ pngtopnm logo.png | ppmquant 224 | pnmnoraw > logo_linux_clut224.ppm


I also had to remove the compiled logo_linux_clut224.c and .o files from '/tmp/work/ccimx6sbc-dey-linux-gnueabi/linux-dey/4.9-r0/build/drivers/video/logo/' to force a recompile.

Reconfigure and recompile the kernel then bake the OS again.
$ bitbake -C configure virtual/kernel
$ bitbake -C compile virtual/kernel
$ bitbake -c cleanall {image}
$ bitbake {image}
