How to display a centered Linux boot logo with DEL5.6 or DEL5.7

Kernel config option for a centered boot logo is available since DEL5.8.
To add this feature to Digi Embedded Linux 5.6 (DEL5.6) or DEL5.7 please save patch below as "centeredlogo.patch"
and apply the patch. For DEL5.6:

# cd /usr/local/DigiEL-5.6/kernel/linux-2.6.31/
# patch -p0 < centeredlogo.patch


For DEL5.7:

# cd /usr/local/DigiEL-5.7/kernel/linux-2.6.35/
# patch -p0 < centeredlogo.patch


Open your project kernel config and search for "logo", select the "centered boot logo" option and build/install your project.

In order to use a custom boot logo (for DEL5.6 and DEL5.7), just add your custom logo to:
$(WORKSPACE)/$(PROJECT)/build/kernel/drivers/video/logo/logo_linux_clut224.ppm
In DEL5.8 there is a kernel option to do custom boot logo (see ESP instructions).
