The TS-7200 models all have 16-bit NOR flash. Update the platform init to support this. Remove the private TS72XX_NOR_* defines and use the common ep93xx defines for the external chip select physical base address instead. Move the NOR flash registration into a static __init function. When the NAND flash support is updated this function will also be used to register the NAND flash for the TS-7250 and TS-7260.

To allow these checks, store the machine flags in the lowcore when the machine type has been detected.

This is not required, as that will be handled by the level interrupt handler. This change simplifies the MSP4200 code to remove the masking in the ack routine, and makes sure that the minimum required operation is performed for masking and acking, rather than always both masking and acking the interrupt.

We were clobbering the entire pt_regs structure in kernel threads leading to random crashes. When switching away from a kernel thread, the saved cp0_status is examined and if bit 30 is set it is cleared and the CP2 state saved into the pt_regs structure. Since the kernel thread stack overlaid the pt_regs structure this resulted in a corrupt stack. When the kthread with the corrupt stack was resumed, it could crash if it used any of the data in the stack that was clobbered. We fix it by moving the kernel thread stack down so it doesn't overlay pt_regs. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

The subsequent call to assign_irq_vector() in arch_enable_uv_irq() migrates the IRQ to another cpu and frees the cpu 0 vector - at least it will be freed as soon as the "IRQ move" completes. arch_enable_uv_irq() needs to send a cleanup IPI to complete the IRQ move. Otherwise, assignment of GRU interrupts on large systems (>200 cpus) will exhaust the cpu 0 interrupt vectors and initialization of the GRU driver will fail.
