When booting an opposite byte sex kernel (e.g. an -LE kernel from BE RedBoot) the current MTD driver fails to handle the -partition table and therefore is unable to generate the correct partition -map for the flash. - -The patch recognises that the FIS directory (the partition table) is -byte-reversed by examining the partition table size, which is known to be -one erase block (this is an assumption made elsewhere in redboot.c).

Use the 'smsc47m1' driver for fan monitoring and control. ++ ++Voltages and temperatures are measured by an 8-bit ADC, the resolution ++of the temperatures is 1 bit per degree C. ++Voltages are scaled such that the nominal voltage corresponds to ++192 counts, i.e. 3/4 of the full range. Thus the available range for ++each voltage channel is 0V ... 255/192*(nominal voltage), the resolution ++is 1 bit per (nominal voltage)/192. ++Both voltage and temperature values are scaled by 1000, the sys files ++show voltages in mV and temperatures in units of 0.001 degC. ++ ++The +12V analog voltage input channel (in4_input) is multiplexed with ++bit 4 of the encoded CPU voltage. This means that you either get ++a +12V voltage measurement or a 5 bit CPU VID, but not both. ++The default setting is to use the pin as 12V input, and use only 4 bit VID. ++This driver assumes that the information in the configuration register ++is correct, i.e. that the BIOS has updated the configuration if ++the motherboard has this input wired to VID4. ++ ++The temperature and voltage readings are updated once every 1.5 seconds. ++Reading them more often repeats the same values. ++ ++ ++sysfs interface ++--------------- ++ ++in0_input - +2.5V voltage input ++in1_input - CPU voltage input (nominal 2.25V) ++in2_input - +3.3V voltage input ++in3_input - +5V voltage input ++in4_input - +12V voltage input (may be missing if used as VID4) ++in5_input - Vcc voltage input (nominal 3.3V) ++ This is the supply voltage of the sensor chip itself. ++in6_input - +1.5V voltage input ++in7_input - +1.8V voltage input ++ ++in[0-7]_min, ++in[0-7]_max - lower and upper alarm thresholds for in[0-7]_input reading ++ ++ All voltages are read and written in mV. ++ ++in[0-7]_alarm - alarm flags for voltage inputs ++ These files read '1' in case of alarm, '0' otherwise. ++ ++temp1_input - chip temperature measured by on-chip diode ++temp[2-3]_input - temperature measured by external diodes (one of these would ++ typically be wired to the diode inside the CPU) ++ ++temp[1-3]_min, ++temp[1-3]_max - lower and upper alarm thresholds for temperatures ++ ++temp[1-3]_offset - temperature offset registers ++ The chip adds the offsets stored in these registers to ++ the corresponding temperature readings. ++ Note that temp1 and temp2 offsets share the same register, ++ they cannot both be different from zero at the same time. ++ Writing a non-zero number to one of them will reset the other ++ offset to zero. ++ ++ All temperatures and offsets are read and written in ++ units of 0.001 degC. ++ ++temp[1-3]_alarm - alarm flags for temperature inputs, '1' in case of alarm, ++ '0' otherwise. ++temp[2-3]_input_fault - diode fault flags for temperature inputs 2 and 3. ++ A fault is detected if the two pins for the corresponding ++ sensor are open or shorted, or any of the two is shorted ++ to ground or Vcc.
