libfdt: Add functions to get/add/delete memory reservemap entries This patch adds functions to libfdt for accessing the memory reservation map section of a device tree blob. fdt_num_mem_rsv() retreives the number of reservation entries in a dtb, and fdt_get_mem_rsv() retreives a specific reservation entry. fdt_add_mem_rsv() adds a new entry, and fdt_del_mem_rsv() removes a specific numbered entry. Testcases for these new functions are also included. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

dtc: Add support for variable sized elements Elements of size 8, 16, 32, and 64 bits are supported. The new /bits/ syntax was selected so as to not pollute the reserved keyword space with uint8/uint16/... type names. With this patch the following property assignment: property = /bits/ 16 <0x1234 0x5678 0x0 0xffff>; is equivalent to: property = <0x12345678 0x0000ffff>; It is now also possible to directly specify a 64 bit literal in a cell list, also known as an array using: property = /bits/ 64 <0xdeadbeef00000000>; It is an error to attempt to store a literal into an element that is too small to hold the literal, and the compiler will generate an error when it detects this. For instance: property = /bits/ 8 <256>; Will fail to compile. It is also an error to attempt to place a reference in a non 32-bit element. The documentation has been changed to reflect that the cell list is now an array of elements that can be of sizes other than the default 32-bit cell size. The sized_cells test tests the creation and access of 8, 16, 32, and 64-bit sized elements. It also tests that the creation of two properties, one with 16 bit elements and one with 32 bit elements result in the same property contents.

libfdt: Improve sequential write state checking When creating a tree with the sequential write functions, certain things have to be done in a certain order. You must create the memory reserve map and only then can you create the actual tree structure. The -FDT_ERR_BADSTATE return code is for if you try to do things out of order. However, we weren't checking that very thoroughly, so it was possible to generate a corrupted blob if, for example, you started calling fdt_begin_node() etc. before calling fdt_finish_reservemap(). This makes the state checking more thorough disallow that.

libfdt: More tests of NOP handling behaviour In light of the recently discovered bug with NOP handling, this adds some more testcases for NOP handling. Specifically, it adds a helper program which will add a NOP tag after every existing tag in a dtb, and runs the standard battery of tests over trees mangled in this way. For now, this does not add a NOP at the very beginning of the structure block. This causes problems for libfdt at present, because we assume in many places that the root node's BEGIN_NODE tag is at offset 0. I'm still contemplating what to do about this (with one option being simply to declare such dtbs invalid). Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

dtc: cpp co-existence: allow names starting with # to be escaped The device tree language as currently defined conflicts with the C pre- processor in one aspect - when a property or node name begins with a # character, a pre-processor would attempt to interpret it as a directive, fail, and most likely error out. This change allows a property/node name to be prefixed with \. This prevents a pre-processor from seeing # as the first non-whitespace character on the line, and hence prevents the conflict. \ was previously an illegal character in property/node names, so this change is backwards compatible. The \ is stripped from the name during parsing by dtc. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: David Gibson <david@gibson.dropbear.id.au>

Support ePAPR compliant phandle properties Currently, the Linux kernel, libfdt and dtc, when using flattened device trees encode a node's phandle into a property named "linux,phandle". The ePAPR specification, however - aiming as it is to not be a Linux specific spec - requires that phandles be encoded in a property named simply "phandle". This patch adds support for this newer approach to dtc and libfdt. Specifically: - fdt_get_phandle() will now return the correct phandle if it is supplied in either of these properties - fdt_node_offset_by_phandle() will correctly find a node with the given phandle encoded in either property. - By default, when auto-generating phandles, dtc will encode it into both properties for maximum compatibility. A new -H option allows either only old-style or only new-style properties to be generated. - If phandle properties are explicitly supplied in the dts file, dtc will not auto-generate ones in the alternate format. - If both properties are supplied, dtc will check that they have the same value. - Some existing testcases are updated to use a mix of old and new-style phandles, partially testing the changes. - A new phandle_format test further tests the libfdt support, and the -H option.

dtbs_equal_ordered \
dtc: Extend and better test dtbs_equal utility programs (resend) The dtbs_equal_ordered test program is used to implement a number of testcases. However, the test program itself has never been particularly well tested. In addition there are testcases coming in future for which it would be useful to have a corresponding "dtbs_equal_unordered" which checks for equality of device trees, not considering the internal ordering of elements. Finally, for some tests we may want it would be useful to check trees for equality with the PASS case being when they are *not* equal. This patch addresses all of the above. A dtbs_equal_unordered is added, and both it and the existing dtbs_equal_ordered program now take a -n option to make the PASS case be where the trees are not equal. A number of example trees with slight modifications from test_tree1 are used to verify that both these programs correctly identify when the tree is altered, and a dtb_reverse program is used to verify that the unordered version does not depend on internal ordering. These new testcases for the equality testing programs are split out into a new test group in run_tests.sh. dtbs_equal_unordered uses the new property iteration functions, and so this also acts as further testing for those functions. dtbs_equal_unordered will be useful for further testing the recently added tree-merging code and its upcoming extensions.

dtc: Make asm output more portable and add testcases This patch adds some testcases for dtc's -Oasm mode. Specifically it checks that building the asm will result in the same device tree blob in memory as -Odtb mode would produce, for a variety of trees. This test uncovered two difficulties with our current -Oasm output, both of which are addressed in this patch as well. First, -Oasm output would only be correct if assembled for a big-endian target. Usually that would be the case, when building device trees into a firmware or similar. However this makes life inconvenient for testing on a little-endian target, and one can think up use cases where a program running on a little endian host might want to embed a device tree for a big-endian target. This patch therefore changes -Oasm output to use .byte directives instead of .long throughout in order to generate byte-for-byte identical trees regardless of the endianness of the assembler target. Second, -Oasm output emitted several #define statements which were then used in the innards of the output - i.e. it assumed the output would be processed by cpp before being assembled. That may not be convenient in all build environments, and in any case doesn't work well with the above fix. So, -Oasm output no longer needs to be preprocessed before assembling.

Fix dtc bugs for 64-bit compile I've just tested building dtc as an x86_64 binary on a 32-bit i386 host by using: make CC="gcc -m64" This patch fixes a handful of minor bugs thus discovered: * There is a printf() type mismatch on 64-bit in value-labels.c * For the tests which use libdl, we were using the GNU make feature where it will find libdl.so given a dependency in the form '-ldl'. But this built-in make logic doesn't know we're compiling 64-bit so finds the 32-bit version of the library. We avoid using this and instead explicitly pass -ldl to CC, which being the 64-bit version does know where to look. * To process dtc's asm output into .so files, run_tests.sh was directly invoking the (default instance of) the assembler and linker. Instead invoke these via the CC driver, and allow that to be overriden from the make environment. * The x86_64 assembler doesn't 0 fill with the .balign directive (presumably it is NOP filling). That doesn't produce strictly incorrect trees, but it is confusing and confounds are testcases which do byte-by-byte comparison of the trees produced by asm output with direct dtb output (which does 0 pad where necessary, of course). This patch uses the optional second argument to .balign to force gas to zero-fill instead. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

dtc: Make asm output more portable and add testcases This patch adds some testcases for dtc's -Oasm mode. Specifically it checks that building the asm will result in the same device tree blob in memory as -Odtb mode would produce, for a variety of trees. This test uncovered two difficulties with our current -Oasm output, both of which are addressed in this patch as well. First, -Oasm output would only be correct if assembled for a big-endian target. Usually that would be the case, when building device trees into a firmware or similar. However this makes life inconvenient for testing on a little-endian target, and one can think up use cases where a program running on a little endian host might want to embed a device tree for a big-endian target. This patch therefore changes -Oasm output to use .byte directives instead of .long throughout in order to generate byte-for-byte identical trees regardless of the endianness of the assembler target. Second, -Oasm output emitted several #define statements which were then used in the innards of the output - i.e. it assumed the output would be processed by cpp before being assembled. That may not be convenient in all build environments, and in any case doesn't work well with the above fix. So, -Oasm output no longer needs to be preprocessed before assembling.

tests: Better testing of dtc -I fs mode Greg Kurz added a trivial test of the -I fs mode recently, which was previously basically untested. This is an oversight, since we recently had a bug which completely broke it. This replaces Greg's test with a more thorough test of -I fs mode. We use a test helper to create the familiar test_tree1 in "fs" form, then use dtc -I fs to process it, and check that the results match what they should. We only check the content in -I fs -O dtb mode, since that's simplest, but we do run -I fs -O dts mode as well to make sure it doesn't blow up (the aforementioned bug caused just such a blow up, specific to -O dts mode, for example).

However many installation systems expect to be able to change to the directory containing setup.py and run it. This allows them to support (for example) building/installing for multiple Python versions, varying installation paths, particular C flags, etc. The problem in implementing this is that we don't want to duplicate the information in the Makefile. A common solution (so I am told) is to parse the Makefile to obtain the required information.

dtc: Add valgrind support to testsuite This patch adds some options to the run_tests.sh script allowing it to run all the testcases under valgrind to check for pointer corruption bugs and memory leaks. Invoking "make checkm" will run the testsuite with valgrind. It include a mechanism for specifying valgrind errors to be suppressed on a per-testcase basis, and adds a couple of such suppression files for the mangle-layout and open_pack testcases which dump for use by other testcases a buffer which may contain uninitialized sections. We use suppressions rather than initializing the buffer so that valgrind will catch any internal access s to the uninitialized data, which would be a bug. The patch also fixes one genuine bug caught by valgrind - _packblocks() in fdt_rw.c was using memcpy() where it should have been using memmove(). At present the valgrinding won't do anything useful for testcases invoked via a shell script - which includes all the dtc testcases. I plan to fix that later.
