[POWERPC] Support for "weird" MPICs and fixup mpc7448_hpc2
This adds a new hardware information table for mpic. This enables the mpic code to deal with mpic controllers with different register layouts and hardware behaviours. This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic controllers, select CONFIG_MPIC_WEIRD and add its hardware information in the mpic_infos[] array. TSI108/109 PIC takes the first index of weird hardware information table. :) The table can be extended. The Tsi108/109 PIC looks like standard OpenPIC but, in fact, is different in register mapping and behavior. The patch does not affect the behavior of standard mpic. If CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to the current code. [benh@kernel.crashing.org: This patch is a slightly cleaned up version of Zang Roy's support for the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new version of the type macros and changes the way MPIC is selected in Kconfig to better match what is done for other system devices. ] Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
