dtoc: Make integer division python 3.x safe

2016-10-09T15:30:32+00:00

If we use the '/' operator then python 3.x will produce a float, and
refuse to multiply the string sequence in Conv_name_to_c by it with:

    TypeError: can't multiply sequence by non-int of type 'float'

Use the '//' operator instead to enforce that we want integer rather
than floating point division.

dtoc: Decode strings for struct.unpack on python 3.x

2016-10-09T15:30:32+00:00

On python 3.x struct.unpack will complain if we provide it with a
string since it expects to operate on a bytes object. In order to
satisfy this requirement, encode the string to a bytes object when
running on python 3.x.

dtoc: Use items() to iterate over dictionaries in python 3.x

2016-10-09T15:30:32+00:00

In python 3.x the iteritems() method has been removed from dictionaries,
and the items() method does effectively the same thing. On python 2.x
using items() is a little less efficient since it involves copying data,
but as speed isn't a concern in the affected code switch to using
items() anyway for simplicity.

dtoc: Add a way for tests to request the fallback library

2016-10-09T15:30:32+00:00

We need to test both the normal (Python libfdt module) and fallback (fdtget)
implementations of the Fdt class. Add a way to select which implementation
to use.

dtoc: Adjust GetProps() in fdt_normal to use the node path

2016-10-09T15:30:32+00:00

There is no need to pass a node path separately. Instead we should use the
path for the node provided. Correct this.

dtoc: Fix bug in GetProp()

2016-10-09T15:30:32+00:00

This does not actually call fdtget correctly when requesting a particular
type. Fix it.

dtoc: Add methods for reading data from properties

2016-09-19T03:04:39+00:00

Provide easy helpers for reading integer, string and boolean values from
device-tree properties.

dtoc: Correct quotes in fdt_util

2016-09-19T03:04:39+00:00

The style is to use single quotes for strings where possible. Adjust this
function.

dtoc: Support finding the offset of a property

2016-09-19T03:04:39+00:00

Add a way to find the byte offset of a property within the device tree. This
is only supported with the normal libfdt implementation since fdtget does
not provide this information.

dtoc: Support packing the device tree

2016-09-19T03:04:39+00:00

After any node/property deletion the device tree can be packed to remove
spare space. Add a way to perform this operation.

Note that for fdt_fallback, fdtput automatically packs the device tree after
deletion, so no action is required here.
