There are numerous sub-commands, this makes it possible to call the others.
Also in this patch is the ability for the "default" ATA driver to
query smart data too

Cortex-M processors don't have an MMU, but can still have caches
that need software management, so on those platforms we don't want
to include the MMU related functions.
While here, remove an outdated section of a comment referring to
deprecated cache maintenance functions which no longer exist.

On PATA, we'd cap our transers at UDMA2 if the device reported that an
80 pin cable wasn't detected, but SATA devices do not perform this test.
So alter the check to only apply on PATA devices, so that SATA devices
can run at full UDMA speeds.

This allows to reuse a register definition across similar SoCs that have the same layout of registers (same offsets), but are using a different base address for the peripheral. The include guard was also fixed to reflect the new file name of the header.
Some registers were renamed in order to match the datasheet and for consistency with the other register numbering.

This is part of the preparation to add support for iPod Nano 3G and Nano 4G. There are some optimisations left, like merging similar blocks of registers that share the same layout, but the base address have changed between SoC generations.

No functional change.
We always have it turned in for ipod6g, but this makes some of the
flow/logic easier to follow.

Basically this requires un-hardcoding SECTOR_SIZE everywhere, in
favor of using a variable containing what was reported in IDENTIFY INFO.
Note that the rest of the storage subsystem still needs to be fixed up!

This lets us *natively* handle varying physical sector sizes
without playing games and lying about the logical sector size.
(The original drives use 4K _physical_ sectors with 512B logical
sectors, but you have to access everything in 4K blocks...)
Achieve this by splitting the MAX_PHYS_SECTOR_SIZE code out
of the main ATA driver and re-using it.

....It's specified in 16-bit words, not bytes. So multiply it by 2.
(This hasn't been a problem in practice as everything uses 512B logical
sectors so far..)

* FLUSH_EXT is used if featureflag is set and we are using LBA48
(unconditionally used for CE-ATA on ipod6g)
* FLUSH is used if featureflag is set (ATA6+) or if device claims to be ATA5+
* Rename ata_disk_can_power_off() to ata_disk_can_sleep() as that is
what it actually tests for. Only use it to gate issuing the
STANDBY IMMEDIATE command.
* Restore behavior of ata_disk_is_active() to return 1 if drive is
"spinning" or powered up.
* Allow poweroff if drive claims PM support OR we are able to issue
FLUSH/FLUSH_EXT commands.
* Added ata_flush() to explicitly trigger a flush operation, and hook it
up to storage_flush() in the device shutdown path. (Flushes were
only previously used in the storage device power management path)
* After issuing all settings, re-issue IDENTIFY_DEVICE to make sure
it reflects everything we've enabled.
* Update manual section on Flash/SSD mods.

ipod6g was configured with SECTOR_SIZE of 4096, but this ATA driver
unconditionally translated these to 512B operations on the actual
storage device.
Rockbox's storage layer already has robust support for "logical sectors
larger than physical storage sectors" through use of
MAX_LOG_SECTOR_SIZE. So switch to that mechanism, allowing the ipod6g
ATA driver to be simplified.
If we want to support drives with physical sector sizes > 512B, then
we need to port the MAX_PHYS_SECTOR_SIZE logic from the primary ATA driver.
Additional changes:
* Simplify MWDMA/UDMA selection logic
* Report CE-ATA mode in debug menu
* Use LBA48 commands only if drive is over 128GiB.
* Drop default sleep/poweroff time from 20s to 7s (matching main ATA driver)
Finally, the bulk of the changes are the first phase of a badly needed
style cleanup that made reading this driver a lot harder than it should
be. I intend to split this into a separate patch.

Due to the heisenberg principle, we don't want to check the battery
level when the ATA drive is "spun up".
Unfortunately some ATA devices *cough most SD adapters cough* don't
support mandatory ATA power management commands like flushing caches and
(safely) shutting down so we have to leave them "spinning".
This leads to us never updating our battery status with these
out-of-spec devices. Work around this issue by having is_active() always
return false if that's what we have.

* Create new 'sector_t' type alias:
* uint64_t for all targets with HAVE_LBA48 or HAVE_SDUC
* unsigned long for the everything else
* Alter all storage APIs to use sector_t instead of 'unsigned long'
* Alter Volume/Partition/storage info structures to use sector_t
* Disk cache converted to sector_t

* convert to using sector_t for sector addresses and drive sizes
* Always fill out upper 16 bits of LBA48 addresses
* IDENTIFY INFO is fixed at 512 bytes, not SECTOR_SIZE
* USB mass storage:
* convert to using sector_t for sector addesses and drive sizes
* Implement READ_16/WRITE_16 for LBA48 addresses

...by checking to see if the mandatory ATA PM feature flag is set
The common CF->SD adapters don't report this.
TODO: When PM is not available, issue a CMD_FLUSH[_EXT] instead?

* Editing a bunch of drivers' thread routines in order to
implement a new feature is tedious.
* No matter the number of storage drivers, they share one thread.
No extra threads needed for CONFIG_STORAGE_MULTI.
* Each has an event callback called by the storage thread.
* A default callback is provided to fake sleeping in order to
trigger idle callbacks. It could also do other default processing.
Changes to it will be part of driver code without editing each
one.
* Drivers may sleep and wake as they please as long as they give
a low pulse on their storage bit to ask to go into sleep mode.
Idle callback is called on its behalf and driver immediately put
into sleep mode.
* Drivers may indicate they are to continue receiving events in
USB mode, otherwise they receve nothing until disconnect (they
do receive SYS_USB_DISCONNECTED no matter what).
* Rework a few things to keep the callback implementation sane
and maintainable. ata.c was dreadful with all those bools; make
it a state machine and easier to follow. Remove last_user_activity;
it has no purpose that isn't served by keeping the disk active
through last_disk_activity instead.
* Even-out stack sizes partly because of a lack of a decent place
to define them by driver or SoC or whatever; it doesn't seem too
critical to do that anyway. Many are simply too large while at
least one isn't really adequate. They may be individually
overridden if necessary (figure out where). The thread uses the
greatest size demanded. Newer file code is much more frugal with
stack space. I barely see use crack 50% after idle callbacks
(usually mid-40s). Card insert/eject doesn't demand much.
* No forcing of idle callbacks. If it isn't necessary for one or
more non-disk storage types, it really isn't any more necessary for
disk storage. Besides, it makes the whole thing easier to implement.
