One other thing that needs to be considered. The nand driver has an ioctl
for getting chip parameters (see chip_param_io structure in
sys/dev/nand/nand_dev.h) and geom_flashmap only allows for
NAND_IO_GET_CHIP_PARAM to be passed to the provider. However, the CFI and
SPI devices do not implement this and they probably should not as-is.
Something more generic to flash devices that are handled by geom_flashmap
is probably in order.
