19 Ramoops uses a predefined memory area to store the dump. The start and size
20 and type of the memory area are set using three variables:
23 * ``mem_size`` for the size. The memory size will be rounded down to a
25 * ``mem_type`` to specify if the memory type (default is pgprot_writecombine).

32 memory are implementation defined, and won't work on many ARMs such as omaps.
33 Setting ``mem_type=2`` attempts to treat the memory region as normal memory,

63 as before). For quick debugging, you can also reserve parts of memory during
64 boot and then use the reserved memory for ramoops. For example, assuming a
65 machine with > 128 MB of memory, the following kernel command line will tell
66 the kernel to use only the first 128 MB of memory, and place ECC-protected
