Paul Mackerras 390cbb56a7 [POWERPC] Fix detection of loader-supplied initrd on OF platforms ... Commit 79c8541924 introduced code to move the initrd if it was in a place where it would get overwritten by the kernel image. Unfortunately this exposed the fact that the code that checks whether the values passed in r3 and r4 are intended to indicate the start address and size of an initrd image was not as thorough as the kernel's checks. The symptom is that on OF-based platforms, the bootwrapper can cause an exception which causes the system to drop back into OF. Previously it didn't matter so much if the code incorrectly thought that there was an initrd, since the values for start and size were just passed through to the kernel. Now the bootwrapper needs to apply the same checks as the kernel since it is now using the initrd data itself (in the process of copying it if necessary). This adds the code to do that.
