fdt: Merge fdt_normal with its base class

2017-06-02T16:18:20+00:00

Since we only have one Fdt implementation now we don't need to have a base
class. Merge the implementation and the base class together.

fdt: Drop use of the legacy libfdt python module

2017-06-02T16:18:19+00:00

Now that this is no-longer available, stop looking for it. The new module
will be used if available.

fdt: Support use of the new python libfdt library

2017-06-02T16:16:48+00:00

Use the new library if available, while retaining backwards compatibility
with the old library for now.

fdt: Rename existing python libfdt module

2017-06-02T16:16:47+00:00

Now that this module has been accepted upstream we should stop using the
local U-Boot one. In preparation for this, rename it to indicate it is for
legacy 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: 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.

dtoc: Support deleting device tree properties

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

Add support for deleting a device tree property. With the fallback
implementation this uses fdtput. With libfdt it uses the API call and
updates the offsets afterwards.

dtoc: Move to using bytearray

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

Since we want to be able to change the in-memory device tree using libfdt,
use a bytearray instead of a string. This makes interfacing from Python
easier.

dtoc: Prepare for supporting changing of device trees

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

For binman we need to support deleting properties in the device tree. This
will change the offsets of nodes after the deletion. In preparation, add
code to keep track of when the offsets are invalid, and regenerate them.
