Ben Hutchings 45a3fd55ac sfc: Move MTD operations into efx_nic_type
Merge the per-NIC-type MTD probe selection and struct efx_mtd_ops into
struct efx_nic_type.  Move the implementations into the appropriate
source files.

Several NVRAM functions are now only called from MTD operations which
are now implemented in the same file (falcon.c or mcdi.c).  There is no
need for them to be extern, or to be defined at all if CONFIG_SFC_MTD
is not enabled, so move them into the #ifdef CONFIG_SFC_MTD sections
in those files.

Most of the SPI-related definitions are also only used in falcon.c,
so move them there.  Put the remainder of spi.h into nic.h (which
previously included it).

Ben Hutchings b766630b35 sfc: Eliminate struct efx_mtd
Currently we use struct efx_mtd to represent a physical NVRAM device
and struct efx_mtd_partition to represent a partition on that device.
But this only really makes sense for Falcon, as we don't know or care
whether MC-managed NVRAM partitions are on one or more physical
devices.  It complicates iteration and provides little benefit.
Therefore:

- Replace the pointer to efx_mtd in mtd_info::priv with a pointer to efx_nic
- Move the falcon_spi_device pointer into the union in struct efx_mtd_partition
- Move the device name to efx_mtd_partition::dev_type_name
- Move the efx_mtd_ops pointer to efx_nic::mtd_ops
- Make efx_nic::mtd_list a list of partitions

Merge tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6

Pull MTD changes from David Woodhouse:
 - Artem's cleanup of the MTD API continues apace.
 - Fixes and improvements for ST FSMC and SuperH FLCTL NAND, amongst
   others.
 - More work on DiskOnChip G3, new driver for DiskOnChip G4.
 - Clean up debug/warning printks in JFFS2 to use pr_<level>.

Fix up various trivial conflicts, largely due to changes in calling
conventions for things like dmaengine_prep_slave_sg() (new inline
wrapper to hide new parameter, clashing with rewrite of previously last
parameter that used to be an 'append' flag, and is now a bitmap of
'unsigned long flags').

(Also some header file fallout - like so many merges this merge window -
and silly conflicts with sparse fixes)

Shmulik Ladkani 88dfda5f74 sfc: mtd: Use MTD_FAIL_ADDR_UNKNOWN instead of 0xffffffff
As of bb0eb217, MTD_FAIL_ADDR_UNKNOWN should be used to indicate mtd
erase failure not specific to any particular block.

Use MTD_FAIL_ADDR_UNKNOWN instead of 0xffffffff when setting
'erase->fail_addr' in 'efx_mtd_erase()'.

Artem Bityutskiy 3c3c10bba1 mtd: add leading underscore to all mtd functions
This patch renames all MTD functions by adding a "_" prefix:

mtd->erase -> mtd->_erase
mtd->read_oob -> mtd->_read_oob
...

The reason is that we are re-working the MTD API and from now on it is
an error to use MTD function pointers directly - we have a corresponding
API call for every pointer. By adding a leading "_" we achieve the following:

1. Make sure we convert every direct pointer users
2. A leading "_" suggests that this interface is internal and it becomes
   less likely that people will use them directly
3. Make sure all the out-of-tree modules stop compiling and the owners
   spot the big API change and amend them.

Ben Hutchings 5f3f9d6c44 sfc: Consistently test DEBUG macro, not EFX_ENABLE_DEBUG
The netif_dbg() macro is defined in <linux/netdevice.h>.  If the DEBUG
macro is defined, it logs a message at 'debug' level, otherwise it
does nothing.

In net_driver.h we define DEBUG if EFX_ENABLE_DEBUG is defined, but
this is too late for those source files that already got a
definition of netif_dbg() by including <linux/netdevice.h>

Get rid of EFX_ENABLE_DEBUG, and only define and test DEBUG.

In mtd.c, we do not use DEBUG as a condition flag but are forced to
use the DEBUG macro-function from <linux/mtd/mtd.h>.  Undefine DEBUG
before including it.
