removing get_immrbase()??

[Kumar Gala]

I'm not sure if we can actually get away with completely removing  
get_immrbase() but I figured I'd give everyone something to flame me  
about.  The current users are:

CPM/QE related users.

arch/powerpc/include/asm/cpm1.h:#define IMAP_ADDR		(get_immrbase())

	only used drivers/net/fs_enet/fs_enet-main.c which seems evil.

arch/powerpc/platforms/8xx/mpc885ads.h:#define CPM_MAP_ADDR		 
(get_immrbase() + MPC8xx_CPM_OFFSET)
	not used

arch/powerpc/sysdev/cpm1.c:	mpc8xx_immr = ioremap(get_immrbase(),  
0x4000);
	not sure? ideas?

arch/powerpc/include/asm/cpm2.h:#define CPM_MAP_ADDR (get_immrbase() +  
0x80000)
arch/powerpc/sysdev/cpm2.c:	cpm2_immr = ioremap(get_immrbase(),  
CPM_MAP_SIZE);
	these two are related and seem like we could look for "fsl,cpm2"

arch/powerpc/platforms/83xx/misc.c:	restart_reg_base =  
ioremap(get_immrbase() + 0x900, 0xff);
arch/powerpc/platforms/83xx/misc.c:	__be32 __iomem *spcr =  
ioremap(get_immrbase() + SPCR_OFFSET, 4);
arch/powerpc/platforms/83xx/mpc836x_mds.c:			immap =  
ioremap(get_immrbase() + 0x14a8, 8);
arch/powerpc/platforms/83xx/suspend.c:	rcw_regs =  
ioremap(get_immrbase() + IMMR_RCW_OFFSET,
arch/powerpc/platforms/83xx/suspend.c:	immrbase = get_immrbase();
arch/powerpc/platforms/83xx/usb.c:	immap = ioremap(get_immrbase(),  
0x1000);
arch/powerpc/platforms/83xx/usb.c:	immap = ioremap(get_immrbase(),  
0x1000);
arch/powerpc/platforms/83xx/usb.c:	immap = ioremap(get_immrbase(),  
0x1000);
	83xx cruft -- needs more investigation:


arch/powerpc/platforms/86xx/mpc8610_hpcd.c:	clkdvdr =  
ioremap(get_immrbase() + 0xe0800, sizeof(u32));
arch/powerpc/platforms/86xx/mpc86xx_smp.c:	mcm_vaddr =  
ioremap(get_immrbase() + MPC86xx_MCM_OFFSET,
	86xx: the first can be fixed to use guts, the second can be fixed to  
use the new "fsl,mcm" that I proposed:

arch/powerpc/sysdev/fsl_pci.c:	immr_base = get_immrbase();
	This one is a bit more problematic but can use the new "fsl,mcm-law",  
"fsl,ecm-law"
