Since bootdevice never gets initialized, it's always NULL, and hence a

(This was the code that originally was there so that the automatic

set_irq_chained_handler overwrites MPIC's handle_irq function
(handle_fasteoi_irq) thus MPIC never gets eoi event from the
cascaded IRQ. This situation hangs MPIC on MPC8568E.

To solve this problem efficiently, QEIC needs pluggable handlers,
specific to the underlaying interrupt controller.

Patch extends qe_ic_init() function to accept low and high interrupt
handlers. To avoid #ifdefs, stack of interrupt handlers specified in
the header file and functions are marked 'static inline', thus
handlers are compiled-in only if actually used (in the board file).
Another option would be to lookup for parent controller and
automatically detect handlers (will waste text size because of
never used handlers, so this option abolished).

qe_ic_init() also changed in regard to support multiplexed high/low
lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic()
handler implemented appropriately.

The CONFIG_FSL_BOOKE mmu setup code fails when CONFIG_HIGHMEM=y
and the 3 fixed TLB entries cannot exactly map the lowmem size.
Each TLB entry can map 4MB, 16MB, 64MB or 256MB, so the failure
is observed when the kernel lowmem size is not equal to the
sum of up to 3 of those values.

Normally, memory is sized in nice numbers, but I observed this
problem while testing a crash dump kernel.  The failure can
also be observed by artificially reducing the kernel's main
memory via the mem= kernel command line parameter.

This commit fixes the problem by setting __initial_memory_limit
in adjust_total_lowmem().

This patch makes numerous miscellaneous code improvements to the QE library.

1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type()
   (every caller of ucc_init_guemr() also calls ucc_set_type()).  Modify all
   callers of ucc_set_type() accordingly.

2. Remove the unused enum ucc_pram_initial_offset.

3. Refactor qe_setbrg(), also implement work-around for errata QE_General4.

4. Several printk() calls were missing the terminating \n.

5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where
   appropriate.

6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed
   with the wrong value.

7. Add the protocol type to struct us_info and updated ucc_slow_init() to
   use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED.

8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx()

9. Add several macros in qe.h (mostly for slow UCC support, but also to
   standardize some naming convention) and remove several unused macros.

10. Update ucc_geth.c to use the new macros.

11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol
    to use when initializing the UCC in ucc_slow_init().

12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since
    these are the real names of the registers.

13. Use the setbits, clrbits, and clrsetbits where appropriate.

14. Refactor ucc_set_qe_mux_rxtx().

15. Remove all instances of 'volatile'.

16. Simplify get_cmxucr_reg();

17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[].

18. Updated struct ucc_geth because struct ucc_fast is not padded any more.

The way the current CPM binding describes available multi-user (a.k.a.
dual-ported) RAM doesn't work well when there are multiple free regions,
and it doesn't work at all if the region doesn't begin at the start of
the muram area (as the hardware needs to be programmed with offsets into
this area).  The latter situation can happen with SMC UARTs on CPM2, as its
parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't
support moving it.

It is now described with a muram node, similar to QE.  The current CPM
binding is sufficiently recent (i.e. never appeared in an official release)
that compatibility with existing device trees is not an issue.

The code supporting the new binding is shared between cpm1 and cpm2, rather
than remain separated.  QE should be able to use this code as well, once
minor fixes are made to its device trees.

Previously, Soft_emulate_8xx was called with no implementation, resulting in

However, this sort of minimal emulation is not a very good idea other than
for compatibility with existing userspaces, as it's less efficient than
soft-float and can mislead users into believing they have soft-float.  Thus,
it is made a configurable option, off by default.
