[U-Boot-Users] [PATCH] update to the exports table

[Jeff Mann]

Hey u-boot list:
 
I've attached a patch for adding function to the exports table for your
review. 
 
In exports.c, I added a function called xf_func_inc(int) which can be
called from an external program and used to determine which functions
were compiled with u-boot and available. (this is done by making sure
that the jump table entry does not point to the dummy function) For
example, if u-boot is compiled without NAND support, a stand alone
program can find out before calling the do_nand function. This seemed to
be the simplest way to implement this functionality, but if anyone has a
better idea, I'll look into it. 
 
Also in exports.c, I reordered the "gd->jt[XF_xxxx] = (void *) xxxx;"
entries to be grouped into a more logical grouping order so that the #if
statements were together.

In _exports.h, I added my new functions below existing functions so that
the enumerated name and number (XF_xxxx) that get assigned to the
existing functions would not change. Also, I removed the #if...
Statements so that the enumerated numbers assigned never change when
u-boot is compiled with different configurations and options enabled. 
 
In exports.h Function declarations were added and the XF_VERSION was
incremented to 4.

netboot_common was changed from static to extern. 

If there are no discussions about this, then Wolfgang and Stefan please
add it to the tree.
