I've extracted a defined interface for the _current_ bd_t
structure so far. I'm telling you, you're not going to
like it... :-)
So what do you want to do with it? Specifically, my tree
is in this state:
- I have made two files, a .c and a .h that contain
essentially a grand-union of all of the bd_t and
board_info structure definitions that I could find.
- I have introduced shim function definitions that are
simple accessor functions to front the common structure
It is semi gross in that this file contains a plethora of
#ifdef messes that span multiple PPC32 boards and architectures.
Whereas these used to be nicely distributed (:-)) they are
all gathered into one place that clearly demonstrates a
- This is wrong and needs to be cleaned up more :-),
- Obvious refactoring for common functionality that
is NOT board-specific is still needed,
- There are 51 unique fields in all the bd_t defs.
I am currently proving that various platforms still build.
I'm not going to be able to run-test any boards except
a limited few.
I will happily supply a diff of my messings to the list or
a few individuals who want it.
