Hi all,
Here is a bunch of small updates / fix for Freescale MPC52xx. Some of
them are now required for a proper compilation.
They mostly only modify the mpc52xx specific code and not much common code.
Theses are in my tree since some time now and have been tested by
several peoples.
As usual, a BK tree is available with all of theses changes :
bk://bkbits.246tNt.com/linux-2.5-mpc52xx-pending
Comments / Reports are welcome.

# - Remove the 'volatile' keyword in structs defining hardware
registers sets.
# This keyword is useless and can even be harmful if it makes
someone believes
# it's sufficient to access a register like a variable. It's not !
And the
# registers must be accessed with the appropriate in_be/out_be. So
we remove
# this keyword as it's wrong and misleading.
# - Some fixes to SDMA
# - Add SRAM unit

Hello
Sorry for this late one, I just got it and it belongs with the others.
I've added it to the bk tree I sent earlier (
bk://bkbits.246tNt.com/linux-2.5-mpc52xx-pending )
so please pull from that tree.
The unified diff along with the patch description is below.
Thanks,
Sylvain
