-# Standard 224-color Linux logo
to change it you’ll need to recompile the kernel
edit > after some search, linux convert ppm to a c file with two different array at compile time,
resulting uImage file contain uboot header, zImage kernel and some gziped data,
using dd to separate parts work fine and binwalk show us a lot, but fix & recompose uImage seem at first look an impossible mission =)
there is a logo.nologo boot parameter but i not found any override boot logo parameter, only viable solution to change splash screen only seem full recompilation.
