[ECOS] IMM base for MPC8xx based Targets

[Wolfgang Heppner <hep at iis dot fhg dot de>]

Hi,

i am porting my application from eCos 1.3.1 to the current CVS-Version.
I am using a MPC8xx based board and derived my platform hal from the
mbx-hal.

I noticed that some init-functions failed, because the definition of the
IMM baseaddress (CYGARC_REG_IMM_BASE in
packages/hal/powerpc/mpc8xx/current/include/var_regs.h) has changed (my
platform still uses 0xff000000 as IMM base)! As a workaround i had to
change the variant hal.

The location of the internal memorymap is platform dependend (it can be
configured in hardware during power-up). 
Therefore there should be a way to set the IMM baseaddress in the
platform hal (not in the variant hal) or even better - it should be
configurable. Or did i miss anything?

Thanks
Wolfgang
