I'm testing the ppc platform is based on mpc85xx. 256MB Flash memory
has been installed. Then I found this entries.
0xc9100000-0xd9101000 268439552 of_flash_probe+0x290/0x814 ioremap
physmap_of allocated 268MB over to the vmalloc. vmalloc space is tight.
Why does we need mpc platforms to flash memory allocation? I know
other architectures don't allocate to the vmalloc.
The design of the hardware? or Is there the way to use the flash
memory without vmalloc?
