Export redesign
this is an atempt to make the export of functions typesafe. I replaced the jumptable void ** by a struct (jt_funcs) with function pointers. The EXPORT_FUNC macro now has 3 fixed parameters and one variadic parameter The first is the name of the exported function, the rest of the parameters are used to format a functionpointer in the jumptable, the EXPORT_FUNC macros are expanded three times, 1. to declare the members of the struct 2. to initialize the structmember pointers 3. to call the functions in stubs.c Signed-off-by: Martin Dorwig <dorwig@tetronik.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> (resending to the list since my tweaks are not quite trivial)

table is allocated and initialized in the jumptable_init() routine
|
||||
(common/exports.c). Other routines may also modify the jump table,
|
||||
however. The jump table can be accessed as the 'jt' field of the
|
||||
'global_data' structure. The slot numbers for the jump table are
|
||||
'global_data' structure. The struct members for the jump table are
|
||||
defined in the <include/exports.h> header. E.g., to substitute the
|
||||
malloc() and free() functions that will be available to standalone
|
||||
applications, one should do the following:
|
||||
|
||||
DECLARE_GLOBAL_DATA_PTR;
|
||||
|
||||
gd->jt[XF_malloc] = my_malloc;
|
||||
gd->jt[XF_free] = my_free;

||||
gd->jt->malloc = my_malloc;
|
||||
gd->jt->free = my_free;
|
||||
|
||||
Note that the pointers to the functions all have 'void *' type and
|
||||
thus the compiler cannot perform type checks on these assignments.
|

Note that the pointers to the functions are real function pointers

|

5. To export some additional function long foobar(int i,char c), the following steps
|
||||
should be undertaken:
|
||||
|
||||
- Append the following line at the end of the include/_exports.h
|
||||
file:
|
||||
|
||||
EXPORT_FUNC(foobar)
|
||||
EXPORT_FUNC(foobar, long, foobar, int, char)
|
||||
|
||||
Parameters to EXPORT_FUNC:
|
||||
- the first parameter is the function that is exported (default implementation)
|
||||
- the second parameter is the return value type
|
||||
- the third parameter is the name of the member in struct jt_funcs
|
||||
this is also the name that the standalone application will used.
|
||||
the rest of the parameters are the function arguments
|
||||
|
||||
- Add the prototype for this function to the include/exports.h
|
||||
file:
|
||||
|
||||
void foobar(void);
|
||||
long foobar(int i, char c);
|
||||
|
||||
- Add the initialization of the jump table slot wherever
|
||||
appropriate (most likely, to the jumptable_init() function):
|
||||
Initialization with the default implementation is done in jumptable_init()
|
||||
|
||||
gd->jt[XF_foobar] = foobar;
|
||||
You can override the default implementation using:
|
||||
|
||||
gd->jt->foobar = another_foobar;
|
||||
|
||||
The signature of another_foobar must then match the declaration of foobar.
|
||||
|
||||
- Increase the XF_VERSION value by one in the include/exports.h
|
||||
file
|
||||
|
||||
- If you want to export a function which depends on a CONFIG_XXX
|
||||
use 2 lines like this:
|
||||
#ifdef CONFIG_FOOBAR
|
||||
EXPORT_FUNC(foobar, long, foobar, int, char)
|
||||
#else
|
||||
EXPORT_FUNC(dummy, void, foobar, void)
|
||||
#endif
|
||||
|
||||
|
||||

||||
