Hi all,
In our bootloader based off of 2013.07 we make extensive use of the flat
device tree. In profiling our bootloader in our simulator I found that
the function eating up the most time is fdt_next_tag. Looking at it,
especially fdt_offset_ptr, it looks like there is a lot of room for
improvement especially in the skip name section.
Some of the checks in fdt_offset_ptr also look useless, such as if
((offset + len) < offset) which will always be false, or
if (p + len < p)
len is always positive.
