What this usually means is that they a) use software published under the GPL, or b) use derivatives of software published under the GPL, or c) link against software published under the GPL, without, as the GPL requires, making freely available the source code of said software.
To what extent this applies to Jinke, i.e. which GPL'd software they use or link against, I don't know, although their using a variant of Linux certainly means that they at least must offer the source code of the version of Linux used, in order to satisfy the GPL. Which, AFAIK, they don't (unless it's part of the SDK?)
