/*
* linux/byteorder/generic.h
* Generic Byte-reordering support
*
* The "... p" macros, like le64_to_cpup, can be used with pointers
* to unaligned data, but there will be a performance penalty on
* some architectures. Use get_unaligned for unaligned data.
*
* Francois-Rene Rideau <fare@tunes.org> 19970707
* gathered all the good ideas from all asm-foo/byteorder.h into one file,
* cleaned them up.
* I hope it is compliant with non-GCC compilers.
* I decided to put __BYTEORDER_HAS_U64__ in byteorder.h,
* because I wasn't sure it would be ok to put it in types.h
* Upgraded it to 2.1.43
* Francois-Rene Rideau <fare@tunes.org> 19971012
* Upgraded it to 2.1.57
* to please Linus T., replaced huge #ifdef's between little/big endian
* by nestedly #include'd files.
* Francois-Rene Rideau <fare@tunes.org> 19971205
* Made it to 2.1.71; now a facelift:
* Put files under include/linux/byteorder/
* Split swab from generic support.
*
* TODO:
* = Regular kernel maintainers could also replace all these manual
* byteswap macros that remain, disseminated among drivers,
* after some grep or the sources...
* = Linus might want to rename all these macros and files to fit his taste,
* to fit his personal naming scheme.
* = it seems that a few drivers would also appreciate
* nybble swapping support...
* = every architecture could add their byteswap macro in asm/byteorder.h
* see how some architectures already do (i386, alpha, ppc, etc)
* = cpu_to_beXX and beXX_to_cpu might some day need to be well
* distinguished throughout the kernel. This is not the case currently,
* since little endian, big endian, and pdp endian machines needn't it.
* But this might be the case for, say, a port of Linux to 20/21 bit
* architectures (and F21 Linux addict around?).
*/
/*
* The following macros are to be defined by <asm/byteorder.h>:
*
* Conversion of long and short int between network and host format
* ntohl(__u32 x)
* ntohs(__u16 x)
* htonl(__u32 x)
* htons(__u16 x)
* It seems that some programs (which? where? or perhaps a standard? POSIX?)
* might like the above to be functions, not macros (why?).
* if that's true, then detect them, and take measures.
* Anyway, the measure is: define only ___ntohl as a macro instead,
* and in a separate file, have
* unsigned long inline ntohl(x){return ___ntohl(x);}
*
* The same for constant arguments
* __constant_ntohl(__u32 x)
* __constant_ntohs(__u16 x)
* __constant_htonl(__u32 x)
* __constant_htons(__u16 x)
*
* Conversion of XX-bit integers (16- 32- or 64-)
* between native CPU format and little/big endian format
* 64-bit stuff only defined for proper architectures
* cpu_to_[bl]eXX(__uXX x)
* [bl]eXX_to_cpu(__uXX x)
*
* The same, but takes a pointer to the value to convert
* cpu_to_[bl]eXXp(__uXX x)
* [bl]eXX_to_cpup(__uXX x)
*
* The same, but change in situ
* cpu_to_[bl]eXXs(__uXX x)
* [bl]eXX_to_cpus(__uXX x)
*
* See asm-foo/byteorder.h for examples of how to provide
* architecture-optimized versions

* In arch/{i386,x86_64}/kernel/setup.c, this information is

* information is used to identify BIOS boot disk. The code in setup.S

/**
* fdt_first_region() - find regions in device tree
*
* Given a nodes and properties to include and properties to exclude, find
* the regions of the device tree which describe those included parts.
*
* The use for this function is twofold. Firstly it provides a convenient
* way of performing a structure-aware grep of the tree. For example it is
* possible to grep for a node and get all the properties associated with
* that node. Trees can be subsetted easily, by specifying the nodes that
* are required, and then writing out the regions returned by this function.
* This is useful for small resource-constrained systems, such as boot
* loaders, which want to use an FDT but do not need to know about all of
* it.
*
* Secondly it makes it easy to hash parts of the tree and detect changes.
* The intent is to get a list of regions which will be invariant provided
* those parts are invariant. For example, if you request a list of regions
* for all nodes but exclude the property "data", then you will get the
* same region contents regardless of any change to "data" properties.
*
* This function can be used to produce a byte-stream to send to a hashing
* function to verify that critical parts of the FDT have not changed.
* Note that semantically null changes in order could still cause false
* hash misses. Such reordering might happen if the tree is regenerated
* from source, and nodes are reordered (the bytes-stream will be emitted
* in a different order and many hash functions will detect this). However
* if an existing tree is modified using libfdt functions, such as
* fdt_add_subnode() and fdt_setprop(), then this problem is avoided.
*
* The nodes/properties to include/exclude are defined by a function
* provided by the caller. This function is called for each node and
* property, and must return:
*
* 0 - to exclude this part
* 1 - to include this part
* -1 - for FDT_IS_PROP only: no information is available, so include
* if its containing node is included
*
* The last case is only used to deal with properties. Often a property is
* included if its containing node is included - this is the case where
* -1 is returned.. However if the property is specifically required to be
* included/excluded, then 0 or 1 can be returned. Note that including a
* property when the FDT_REG_SUPERNODES flag is given will force its
* containing node to be included since it is not valid to have a property
* that is not in a node.
*
* Using the information provided, the inclusion of a node can be controlled
* either by a node name or its compatible string, or any other property
* that the function can determine.
*
* As an example, including node "/" means to include the root node and all
* root properties. A flag provides a way of also including supernodes (of
* which there is none for the root node), and another flag includes
* immediate subnodes, so in this case we would get the FDT_BEGIN_NODE and
* FDT_END_NODE of all subnodes of /.
*
* The subnode feature helps in a hashing situation since it prevents the
* root node from changing at all. Any change to non-excluded properties,
* names of subnodes or number of subnodes would be detected.
*
* When used with FITs this provides the ability to hash and sign parts of
* the FIT based on different configurations in the FIT. Then it is
* impossible to change anything about that configuration (include images
* attached to the configuration), but it may be possible to add new
* configurations, new images or new signatures within the existing
* framework.
*
* Adding new properties to a device tree may result in the string table
* being extended (if the new property names are different from those
* already added). This function can optionally include a region for
* the string table so that this can be part of the hash too. This is always
* the last region.
*
* The FDT also has a mem_rsvmap table which can also be included, and is
* always the first region if so.
*
* The device tree header is not included in the region list. Since the
* contents of the FDT are changing (shrinking, often), the caller will need
* to regenerate the header anyway.

*
* For each partition, these fields are available:
* name: string that will be used to label the partition's MTD device.
* size: the partition size; if defined as MTDPART_SIZ_FULL, the partition
* will extend to the end of the master MTD device.
* offset: absolute starting position within the master MTD device; if
* defined as MTDPART_OFS_APPEND, the partition will start where the
* previous one ended; if MTDPART_OFS_NXTBLK, at the next erase block;
* if MTDPART_OFS_RETAIN, consume as much as possible, leaving size
* after the end of partition.
* mask_flags: contains flags that have to be masked (removed) from the
* master MTD flag set for the corresponding MTD partition.
* For example, to force a read-only partition, simply adding
* MTD_WRITEABLE to the mask_flags will do the trick.
