There seemed to be another bug introduced as well as a performance hit
with the addtion of the sentinel descriptor workaround. Removal of
this workaround appears to prevent the hang. We'll take a risk
and remove it, as we had never seen the originally reported bug
under linux.

Moved interrupt masking to before requesting the interrupt from the OS.
Moved interrupt enable to after netif_poll_enable. This fixes a racy
BUG() where polling would be running on another CPU at the same time
that netif_poll_enable would run.

This fixes various odd things that missed update together with cpm_uart
platform_device move. Unified resources names, restructurisation, etc.
Also, addressed issue with recent phys/virt translation rework. Being
cache-coherent, CPM2's do alloc_bootmem() for the console stuff, and it was
used to treat console buffer descriptor mapping 1:1 (as in CPM1 case),
which is definitely wrong.

If a SIR dongle is built in the kernel while IRTTY_SIR is built
as a module, kernel compilation will fail.
Thus, the SIR dongle config should depend on the IRTTY_SIR.

Add read/write function pointers to struct nand_ecc_ctrl to
prepare the modulaization of nand_read/write functions. The
current implementation handles every type of ecc mode
software/hardware and all kinds of strange ecc placement
schemes in one switch/if construct. Thats too complex to
maintain and too inflexible to expand. Modularization will
also shorten the code pathes of the read/write functions.

The nand driver has a superflous read ready / command
delay in the read functions. This was added to handle
chips which have an automatic read forward. Newer
chips do not have this functionality anymore. Add this
option to avoid the delay / I/O operation. Mark all
large page chips with the new option flag.

If we post a list of length exactly a multiple of 256, nreq in
doorbell gets set to 256 which is wrong: it should be encoded by 0.
This is because we only zero it out on the next WR, which may not be
there. The solution is to ring the doorbell after posting a WQE, not
before posting the next one.
This is the same bug that we just fixed for QPs with non-shared RQ.
