What: /sys/bus/pci/devices/.../vpd

Description:
A file named vpd in a device directory will be a
binary file containing the Vital Product Data for the
stage. Just pass the values to this function, and the unsigned int
index returns the number of the frequency table entry which contains
the frequency the CPU shall be set to.
+
+The following macros can be used as iterators over cpufreq_frequency_table:
+
+cpufreq_for_each_entry(pos, table) - iterates over all entries of frequency
+table.
+
+cpufreq-for_each_valid_entry(pos, table) - iterates over all entries,
+excluding CPUFREQ_ENTRY_INVALID frequencies.
+Use arguments "pos" - a cpufreq_frequency_table * as a loop cursor and
+"table" - the cpufreq_frequency_table * you want to iterate over.
+
+For example:
+
+ struct cpufreq_frequency_table *pos, *driver_freq_table;
+
+ cpufreq_for_each_entry(pos, driver_freq_table) {
+ /* Do something with pos */
+ pos->frequency = ...
+ }
- clock-frequency : The frequency of the main counter, in Hz. Optional.
+- always-on : a boolean property. If present, the timer is powered through an
+ always-on power domain, therefore it never loses context.
+
Example:
timer {
* "sata-phy" for the SATA 6.0Gbps PHY
Optional properties:
+- dma-coherent : Present if dma operations are coherent
- status : Shall be "ok" if enabled or "disabled" if disabled.
Default is "ok".

+ Linux can use the full amount of RAM in the system by
+ default. However, the default MMUv2 setup only maps the
+ lowermost 128 MB of memory linearly to the areas starting
+ at 0xd0000000 (cached) and 0xd8000000 (uncached).
+ When there are more than 128 MB memory in the system not
+ all of it can be "permanently mapped" by the kernel.
+ The physical memory that's not permanently mapped is called
+ "high memory".
+
+ If you are compiling a kernel which will never run on a
+ machine with more than 128 MB total physical RAM, answer
+ N here.
+
+ If unsure, say Y.
