with geom_flashmap(4) and teach it about MMC for slicing enhanced user data area partitions. The FDT slicer still is the default for CFI, NAND and SPI flash on FDT-enabled platforms. - In addition to a device_t, also pass the name of the GEOM provider in question to the slicers as a single device may provide more than provider. - Build a geom_flashmap.ko. - Use MODULE_VERSION() so other modules can depend on geom_flashmap(4). - Remove redundant/superfluous GEOM routines that either do nothing or provide/just call default GEOM (slice) functionality. - Trim/adjust includes Submitted by: jhibbits (RouterBoard bits) Reviewed by: jhibbits
