Subject: [PATCH v3 0/3] Variable sized cell support
Date: Fri, 23 Sep 2011 11:02:51 -0700	[thread overview]
Message-ID: <1316800974-30129-1-git-send-email-robotboy@chromium.org> (raw)

This patch set adds, tests, and documents support for variable sized cells in
cell arrays.  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
