[U-Boot] FDT driver initialization function declaration

Hi Simon, Wolfgang and others,

just want to open new topic about FDT driver initialization function
declaration.

There are some drivers which can be simple move to fdt initialization.
I have in my mind ethernet drivers and then systemace (I have ported it).

Ethernet drivers use include/netdev.h file where all initialization
functions are declared.

For example:

diff --git a/include/netdev.h b/include/netdev.h
index 4724717..96e62ee 100644
--- a/include/netdev.h
+++ b/include/netdev.h
@@ -105,6 +105,10 @@ int xilinx_emaclite_initialize(bd_t *bis, unsigned long base_addr,
int xilinx_ll_temac_eth_init(bd_t *bis, unsigned long base_addr, int flags,
unsigned long ctrl_addr);

+#ifdef CONFIG_OF_CONTROL
+int xilinx_emaclite_init(bd_t *bis);
+#endif
+
/*
* As long as the Xilinx xps_ll_temac ethernet driver has not its own interface
* exported by a public hader file, we need a global definition at this point.

But where is the right place for systemace FDT initialization?
include/fdtdec.h?

or create new header and include it to fdtdec.h?

In this case it makes sense to add all FDT driven configuration to one header file
to see what drivers can be used. Even for network drivers.
Also listing all required parameters can be capture there.

What do you think?

Thanks for your comments.

Thanks,
Michal
