bankswitching support in binutils

["David D. Hagood" <david dot hagood at aeroflex dot com>]

I am working with a build of binutils and GCC supplied by Cypress 
Semiconductors for their EZUSB chips. Unfortunately, this code isn't in 
the mainline branches (probably because Cypress didn't want to maintain it).

The chip supports bankswitched memory, but I don't know if bankswitch 
support is in binutils. So, I'd like some pointers as to where to look 
in the code for binutils to see if this is present, and if so, how to 
use it to park routines in different banks.

Also, if the code is NOT there, I'd like any suggestions on how to do 
bankswitching in a reasonably graceful fashion - I am willing to deal 
with C macros to create the trampoline functions, and manually assigning 
code to segments and locating them in banks. Given that this is a 16 bit 
part, can I just assign banks to addresses >64K and then use objdump to 
pull them out?
