At present patman sets the python path on startup so that it can access the libraries it needs. If we convert to use absolute imports this is not necessary. Move patman to use absolute imports. This requires changes in tools which use the patman libraries (which is most of them). Signed-off-by: Simon Glass <sjg@chromium.org>

"""An entry which contains text
|
|
|
|
The text can be provided either in the node itself or by a command-line
|
|
argument. There is a level of indirection to allow multiple text strings
|
|
and sharing of text.
|
|
|
|
Properties / Entry arguments:
|
|
text-label: The value of this string indicates the property / entry-arg
|
|
that contains the string to place in the entry
|
|
<xxx> (actual name is the value of text-label): contains the string to
|
|
place in the entry.
|
|
<text>: The text to place in the entry (overrides the above mechanism).
|
|
This is useful when the text is constant.
|
|
|
|
Example node:
|
|
|
|
text {
|
|
size = <50>;
|
|
text-label = "message";
|
|
};
|
|
|
|
You can then use:
|
|
|
|
binman -amessage="this is my message"
|
|
|
|
and binman will insert that string into the entry.
|
|
|
|
It is also possible to put the string directly in the node:
|
|
|
|
text {
|
|
size = <8>;
|
|
text-label = "message";
|
|
message = "a message directly in the node"
|
|
};
|
|
|
|
or just:
|
|
|
|
text {
|
|
size = <8>;
|
|
text = "some text directly in the node"
|
|
};
|
|
|
|
The text is not itself nul-terminated. This can be achieved, if required,
|
|
by setting the size of the entry to something larger than the text.
