When compling under 64bit platforms, there are lots of warnings, like:
drivers/block/ahci.c:114:18: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] u8 *port_mmio = (u8 *)probe_ent->port[port].port_mmio; ^ drivers/block/ahci.c: In function ?.hci_host_init?. drivers/block/ahci.c:218:49: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] probe_ent->port[i].port_mmio = ahci_port_base((u32) mmio, i);
......

v2: - refined some type casts
Out of curiosity, which toolchain are you using?
ARCH=arm64 CROSS_COMPILE=gcc-linaro-aarch64-linux-gnu-4.8-2013.12_linux/bin/aarch64-linux-gnu-
I believe that any cross compile for arm64 will cause those warnings.

Amicalement,
