706 Although most flash chips have an erase size too large to be useful

709 devices performing that function.

711 At the moment, it is also required for the Journalling Flash File
712 System(s) to obtain a handle on the MTD device when it's mounted
713 (although JFFS and JFFS2 don't actually use any of the functionality
714 of the mtdblock device).
715
716 Later, it may be extended to perform read/erase/modify/write cycles
717 on flash chips to emulate a smaller block size. Needless to say,
718 this is very unsafe, but could be useful for file systems which are

919 help
920 If your product has the RST signal line for the DS1302 RTC on the
921 Generic Port then say Y here, otherwise leave it as N in which
922 case the RST signal line is assumed to be connected to Port PB
923 (just like the SCL and SDA lines).

928 default "2"
929 help
930 This is the bit number for the RST signal line of the DS1302 RTC on
931 the selected port. If you have selected the generic port then it
932 should be bit 27, otherwise your best bet is bit 5.

937 default "1"
938 help
939 This is the bit number for the SCL signal line of the DS1302 RTC on
940 Port PB. This is probably best left at 3.

947 This is the bit number for the SDA signal line of the DS1302 RTC on
948 Port PB. This is probably best left at 2.

952 depends on ETRAX_DS1302
953 default "0"
954 help
955 This controls the initial value of the trickle charge register.
956 0 = disabled (use this if you are unsure or have a non rechargable battery)
957 Otherwise the following values can be OR:ed together to control the
958 charge current:
959 1 = 2kohm, 2 = 4kohm, 3 = 4kohm
960 4 = 1 diode, 8 = 2 diodes
961 Allowed values are (increasing current): 0, 11, 10, 9, 7, 6, 5
