1180feef20 powerpc/boot: Only free if realloc() succeeds
[ Upstream commit f2d5bccaca3e8c09c9b9c8485375f7bdbb2631d2 ]

simple_realloc() frees the original buffer (ptr) even if the
reallocation failed.

Fix it to behave like standard realloc() and only free the original
buffer if the reallocation succeeded.

cd146e3169 powerpc/boot: Handle allocation failure in simple_realloc()
[ Upstream commit 69b0194ccec033c208b071e019032c1919c2822d ]

simple_malloc() will return NULL when there is not enough memory left.
Check pointer 'new' before using it to copy the old data.

4ca478e606 [POWERPC] bootwrapper: Use `unsigned long' for malloc sizes
Use `unsigned long' for malloc sizes, to match common practice and types used
by most callers and callees.
Also use `unsigned long' for integers representing pointers in simple_alloc.
