arch/powerpc/boot/ops.h has:
| /* Platform specific operations */
| struct platform_ops {
| void (*fixups)(void);
| void (*image_hdr)(const void *);
| void * (*malloc)(u32 size);
| void (*free)(void *ptr);
| void * (*realloc)(void *ptr, unsigned long size);
| void (*exit)(void);
| };
Is there a specific reason why the size parameters of malloc() and realloc()
differ in type?
Gr{oetje,eeting}s,

Not as far as I'm aware, I believe it's just a wart. The zImage is
always compiler 32-bit, so they're actually the same thing. I'm
actually hoping to get rid of malloc() and realloc() at some point.

There are good arguments to prefer either u32 or unsigned
long, so maybe the current situation is a compromise ;-P
