> This patch set adds, tests, and documents support for variable sized elements in
> arrays (known as cell lists when they could only support 32-bit entries). The
> new syntax is:
>
> property = /bits/ [8|16|32|64] <0x00 .... 0x12>;
>
> So arrays of 8, 16, 32, or 64-bit elements can now be created. No padding is
> done on the resulting array. So if three 8-bit elements 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)
>
> Changes in v4:
> - Only add phandle reference marker when element size is 32-bits
> - Rename non-terminal celllistprefix to arrayprefix
> - Rename semantic variable celllist to array
> - Update documentation to use array and element instead of cell list and cell
>
> Anton Staaf (3):
> libfdt: Add fdt16_to_cpu utility function
> dtc: Add data_append_integer function
> dtc: Add support for variable sized elements
