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.

dtoc: Allow the device tree to be compiled from source

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

If a source device tree is provide to the Fdt() constructors, compile it
automatically. This will be used in tests, where we want to build a
particular test .dts file and check that it works correctly in binman.

dtoc: Move a few more common functions into fdt.py

2016-09-19T03:04:38+00:00

Some functions have the same code in the subclasses. Move these into the
superclass to avoid duplication.

dtoc: Move Widen() and GetPhandle() into the base class

2016-09-19T03:04:38+00:00

These functions are identical in both subclasses. Move them into the base
class.

Note: In fact there is a bug in one version, which was fixed by this patch:

dtoc: Move BytesToValue() and GetEmpty() into PropBase

2016-09-19T03:04:38+00:00

These functions are currently in a separate fdt_util file. Since they are
only used from PropBase and subclasses, it makes sense for them to be in the
PropBase class.

Move these functions into fdt.py along with the list of types.
