2010-05-10mtd: Blackfin NFC: localize MMR bit masksMike Frysinger
Convert all magic numbers into appropriate defines, and move the defines out of the global namespace and into this one driver. No other driver needs to care about the MMR layout anyways.

2009-06-05mtd: blackfin NFC: fix hang when using NAND on BF527-EZKITsCliff Cai
The DMAs have different bit sizes on BF52x and BF54x. From the PHRM: "The 16-bit DMA Access Bus (DAB) connects the DMA controller to the on-chip peripherals, PPI, SPI, Ethernet MAC, the SPORTs, NFC, HOSTDP and the UARTs." 32-bit DMA won't work for BF52x.

2008-04-22[MTD] [NAND] fix platform driver hotplug/coldplugKay Sievers
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MTD NAND platform drivers, to re-enable auto loading. NOTE: at91_nand for some reason disallows modular builds. I'm assuming that's just an oversight that will be fixed.
