At some point in time Samsung's Open Source Release Center had the package for the GT-S5367 (Galaxy Young TV) smartphone available in their website.
The zipfile was called GT-S5367_GB_Opensource.zip
Which I managed to grab at the time.
It's no longer up there, so here it is the original version.
Mostly unmodified at initial commit, except for sane permissions and line endings fixes.
Code compiles and boots using the bcm21553_totoro_05_tv_defconfig configuration plus two
extra Makefile variables need to be specified in the commandline (alongside the usual ARCH and CROSS_COMPILE):
LTN_BUILD_LOCALE="LTN" and SEC_PROJECT="TOTORO".
