memblock_reserve gets physical address rather than a pfn.

If I read arch/hexagon/include/asm/mem-layout.h correctly, the PHYS_OFFSET
*is* the physical address of the RAM and ARCH_PFN_OFFSET is the first pfn:

#define PHYS_PFN_OFFSET	(PHYS_OFFSET >> PAGE_SHIFT)
#define ARCH_PFN_OFFSET	PHYS_PFN_OFFSET

Did I miss something?
