Sometimes it is useful to specify the default alignment for all entries in a section, such as when word-alignment is necessary, for example. It is tedious and error-prone to specify this individually for each section. Add a property to control this for a section. Signed-off-by: Simon Glass <sjg@chromium.org>

The data passed to mkimage is collected from subnodes of the mkimage node,
|
|
e.g.::
|
|
|
|
mkimage {
|
|
args = "-n test -T imximage";
|
|
|
|
u-boot-spl {
|
|
};
|
|
};
|
|
|
|
This calls mkimage to create an imximage with u-boot-spl.bin as the input
|
|
file. The output from mkimage then becomes part of the image produced by
|
|
binman.
