Hauke Mehrtens d8f1bd2ffc bcma: fix regression in interrupt assignment on mips The wrong interrupts where assigned to the cores in bcma_core_mips_init(). This caused at least my serial console not to response to any input. This was caused by this patch which changed the order of the cores in the list: commit `c334e25c9f` Author: Rafał Miłecki <zajec5@gmail.com> Date: Wed Jul 11 12:37:00 2012 +0200 bcma: add new cores at the end of list This should be fixed properly later so that the correct interrupt numbers are assigned to the cores independently from the ordering of the list. This patch restores the old behavior again. I will look into the problem more deeply later. I also changed the order of the list with the cores and their assigned interrupt number which gets printed to the log. Now they are printed in the same order like all the other lists of cores and like it was done before the patch which changed the order.

README

Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
however from programming point of view there is nothing AMBA specific we use.

Standard AMBA drivers are platform specific, have hardcoded addresses and use
AMBA standard fields like CID and PID.

In case of Broadcom's cards every device consists of:
1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
   as standard AMBA device. Reading it's CID or PID can cause machine lockup.
2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
   and PIDs (0x103BB369), but we do not use that info for anything. One of that
   devices is used for managing Broadcom specific core.

Addresses of AMBA devices are not hardcoded in driver and have to be read from
EPROM.

In this situation we decided to introduce separated bus. It can contain up to
16 devices identified by Broadcom specific fields: manufacturer, id, revision
and class.
