The new syntax is: property = /bits/ [8|16|32|64] <0x00 .... 0x12>; So cell arrays of 8, 16, 32, or 64-bits can now be created. No padding is done on the resulting cell array. So if three 8-bit cells are specified the resulting property will contain three bytes. Changes in v2: - sized_data renamed to celllist - celllist definition moved to dtc-parser.y - celllist non-terminal renamed to celllistprefix - references always appended as -1 masked to the size of the cell - smaller test values derived from TEST_VALUE_1 - data_append_literal renamed to data_append_integer - be_ removed from values in data_append_integer - len renamed to bits in data_append_integer Changes in v3: - Renamed size to bits in docs, parser, commit messages, and celllist struct - Remove die on overflow from data_append_integer - Rewrite data_append_cell|addr in terms of data_append_integer - Minor cosmetic change to property names in test case (added 'b' to last two) Anton Staaf (3): libfdt: Add fdt16_to_cpu utility function dtc: Add data_append_integer function dtc: Add support for variable sized cells Documentation/dts-format.txt | 18 +++++++- data.c | 39 ++++++++++++++++--- dtc-lexer.l | 6 +++ dtc-parser.y | 67 ++++++++++++++++++++++----------- dtc.h | 1 + libfdt/libfdt_env.h | 6 +++ tests/.gitignore | 1 + tests/Makefile.tests | 1 + tests/run_tests.sh | 3 + tests/sized_cells.c | 84 ++++++++++++++++++++++++++++++++++++++++++ tests/sized_cells.dts | 11 +++++ 11 files changed, 205 insertions(+), 32 deletions(-) create mode 100644 tests/sized_cells.c create mode 100644 tests/sized_cells.dts -- 1.7.3.1
