Avoid to re-generate string table from ufdt to fdt

2017-04-13T09:24:15+00:00

String table contains the strings of all property name in a fdt.

The ufdt_apply_overlay() converts two dtbs from fdt to ufdt,
overlays, and converts merged ufdt to fdt. These operations
shouldn't create new peroperty names, so we can just re-use the
string tables in original dtbs, and just copy them into merged
fdt. This solution can enhance a lot of performance for device
tree overlaying.

To avoid the error that some users could use string offset in
string table, the solution also give a same string offset for
the name properties by ufdt_prop_dict;

Futher, the patch also removed unused header files after
changing algorithm.

mkdtimg: reuse identical FDT blobs in dtbo image

2017-04-07T06:33:25+00:00

When multiple dt_table_entries uses the same FDT, do
not keep multiple copies in the output dtbo partition
image. Instead, keep dt_offset in the dt_table_entries
point to the same blob.

Update mkdtimg_testdata.sh to test the above case too.

Fix the problem of not enough merged dtb size

2017-04-05T06:20:17+00:00

The dtc has suffix compression for string, ex. "a_string", "string"
and "ing", these strings could share a same string in dtb
string table. libufdt assumes the merged dtb size shouldn't larger
than the summary size of base and overlay dtb, and doesn't
apply the same compression.

The patch add a test case for this case and fix the problem.
