// The absolutely easiest way to disable FFS altogether is to set
// ffs_flash_manufact = 0x99 and ffs_flash_device = 0x9999. Because this is
// (as of today at least) an undefined device, FFS will NOT initialize and
// every FFS function call will fail (with no side-effects).

// FFS will automatically detect the flash device if both ffs_flash_manufact
// and ffs_flash_device are zero. Note that this works *only* if the flash
// device is mapped at address zero. Otherwise you *have* to supply
// manufacturer and device IDs.

// FFS can be configured to run in ram only. In this case the
// 'ffs_flash_manufact' must be set to MANUFACT_RAM and an address to a
// static user allocated ram buffer must be applied to the variable
// 'ffs_flash_address'. In a ram configuration the 'ffs_flash_device' is an
// arbitrary value that must be in sync with the 'device code' value chosen
// in dev.c.
