+
+Hardware alignment trap
+CONFIG_ALIGNMENT_TRAP
+ ARM processors can not fetch/store information which is not naturally
+ aligned on the bus, ie, a 4 byte fetch must start at an address divisable
+ by 4. On 32-bit ARM processors, these instructions can be emulated in
+ software with a severe performance impact. This is necessary for correct
+ operation of some network protocols. With an IP-only configuration
+ it is safe to say N, otherwise say Y.

+21285 serial port support
+CONFIG_SERIAL_21285
+ If you have a machine based on a 21285 (Footbridge) StrongARM/PCI
+ bridge you can enable its onboard serial port by enabling this
+ option. The device has major ID 4, minor 64.
+
+Console on 21285 serial port
+CONFIG_SERIAL_21285_CONSOLE
+ If you have enabled the serial port on the 21285 footbridge you can
+ make it the console by answering 'Y' to this option.
+
+Footbridge Mode
+CONFIG_HOST_FOOTBRIDGE
+ The 21285 Footbridge chip can operate in either `host mode' or
+ `add-in' mode. Say Y if your 21285 is in host mode, and therefore
+ is the configuration master, otherwise say N.

+MFM harddisk support
+CONFIG_BLK_DEV_MFM
+ Support the MFM hard drives on the Acorn Archimedes both
+ on-board the A4x0 motherboards and via the Acorn MFM podules.
+ Drives upto 64MB are supported. If you haven't got one of these
+ machines or drives just say 'N'.
+
+Old Archimedes floppy (1772) support
+CONFIG_BLK_DEV_FD1772
+ Support the floppy drive on the Acorn Archimedes (A300, A4x0, A540,
+ R140 and R260) series of computers; it supports only 720K floppies
+ at the moment. If you don't have one of these machines just answer
+ 'N'.
+
+Autodetect hard drive geometry
+CONFIG_BLK_DEV_MFM_AUTODETECT
+ If you answer 'Y' the MFM code will attempt to automatically detect
+ the cylinders/heads/sectors count on your hard drive. WARNING: This
+ sometimes doesn't work and it also does some dodgy stuff which
+ potentially might damage your drive.
