sdhci:
- Add semaphore for interrupt management
- Add basic operations (setting clock, executing a command)
- Add early initialization (clocks and power up)
- Wrap the bus in a C++ class to ease usage
- Expose API to MMC bus manager
- TODO: manage card insertion and removal interrupts
- TODO: use MSI when available
mmc_bus:
- Implements SD card management independant of the way we access the bus
(later on different drivers can provide the same API as SDHCI)
- Worker thread to do the initialization
- Implement card initialization process up until getting an RCA from the
card. This is the generic part to assign an ID to the card, after this
point commands can be targetted at the specific card so it can be
handed over to the mmc_disk driver.
- TODO: initialization for non-SDHC cards which do not reply to CMD8.

* This iSCSI implementation only worked on PPC big-endian atm.
* We're pretty sure iSCSI support in haiku_loader doesn't make
much sense anymore. iPXE on (on arm,x86,etc EFI/BIOS platforms)
supports iSCSI boot of disks.
* Haiku could use a iSCSI driver add-on, but it would exist much
higher up and likely use standard drivers vs bare-minimum iSCSI
target impementations.
* Leaving TCP and adding to all arches since it could make sense
for haiku's native network disk subsystem or network debugging?

Some users of MK_ERROR pass in parameters from a variable called "res",
which is obviously not what they want to do, as that will use this "res"
and not theirs.
Spotted by Clang.
* Added B_ prefix.
* Renamed 16 bit variants to B_LENDIAN16_*.
* Added 32 bit variants (albeit only 16 of them for now).
* Adjusted headers that were using them.
* Move to more standardized functions matching AHCI spec
* Don't perform unnecessary double port resets
* Begin implementing a software reset to try first per spec.
Software reset needs more work, falls through to port reset
for the moment which is stable.
* Don't duplicate ATA defines, use what we already provide.
* Tested working on VirtualBox 1-16 AHCI ports, Intel C200,
and AMD FCH.
* The UNMAP command is theoretically much faster, as it can get many block
ranges instead of just a single range.
* Furthermore, the ATA TRIM command resembles it much better.
* Therefore, fs_trim_data now gets an array of ranges, and we use SCSI UNMAP
to trim.
* Updated BFS code to collect array ranges to fully support the new
fs_trim_data possibilities.
* imported asc-num.txt as a reference, was used to generate the asc sense table.
* use the sense asc and key tables to know which action and status codes are
to be applied.
* tested with an hard disk and a dvd reader.
* these tables could be reused by the scsi_periph module.
* The default module is replaced by the Virtio RNG module when found.
* This can have the undesired effect of rendering /dev/urandom slow.
* Tested with the following QEmu command line option:
-device virtio-rng-pci,rng=rng0 -object rng-random,filename=/dev/random,id=rng0
* moved random.h to private/drivers headers.
* added support READ_12/16 and WRITE_12/16 in ata and scsi_periph, this enables read/write on block offsets greater than 2TB

* ata: don't fail if lba_sector_count is null and lba48_sector_count is not
* scsi_periph: if ReadCapacity() returns 0xffffffff, use ReadCapacity16() instead
* scsi_disk: use a different computation in the struct geometry computation for bigger disks
Tested successfully with a virtual 10TB hard drive.

Define structs for iSCSI messages, to be used by boot loader and kernel add-on.
For now it will refuse to compile for Little Endian systems (e.g., x86).

Based on a SCSI Command Reference Manual by Seagate and Wikipedia.
Tested against OpenSolaris iSCSI target on ppc. It choked on the READ (12) opcode.

* Internally, moved the contents of periph_io() into a static read_write()
function, and use it from the new periph_read_write() as well.

* Copied ide_adapter.h as ata_adapter.h in attempt to further
separate the two stacks.
* Continued renaming stuff in drivers/bus/ATA.h
* Make all the busses/ata drivers include the new headers,
specifically ata_types.h, ata_adapter.h and bus/ATA.h,
they were all including ide_types and bus/IDE.h still
* Some renaming of global variables for coding style consistency
* Removed the promise driver from the build, it's not used on the
image and I don't believe it compiled even for the old IDE stack.
* There is no more Command Queueing in the new ATA stack, so I
removed the capability indication from the busses/ata drivers
and ata_adapter.h.
The new ATA stack still boots fine on my computer and I proof-read
the diff like two times. Basically, this was a careful search&replace
job only. The only things I am not sure about is renaming some
publishing related strings, but it seems to all work fine.

* Reworked some of the transfer handling after reading the specs.
* Ensure that the device selection bit is set correctly for all commands.
* Generally disable interrupts and enable them only when expecting a DMA one.
* Renamed disk failure to device fault according to specs.

but doesn't really do anything more than before.
* It also replaces everything IDE with ATA counterparts and cleans up a lot
of the definitions.
* Cleaning up the old ATA bus_manager as well as some license headers missing.

ide_mask_sector_count_48, and ide_mask_LBA_*_48 were all wrong.
* Using the high byte in LBA48 mode should work now, too (wasn't written
to the IDE controller before, but that shouldn't have been a problem yet with
today's disks).

our dma_restrictions structure (but we're using blocks instead of bytes,
since unlike the block size, the restrictions attributes are constant).
* We might want to use blocks for the dma_restrictions structure as well in
the future...
* Fixed another bug in the device_node variant of DMAResource::Init(): the max
segment size was specified in blocks as well.
* Removed the "hardcode" block_io module and header.

architecture: for now, we do this on the lowest layer only, therefore all
requests are handled synchronously (ie. in the scheduler's thread).
* Instead of using the block_io module, scsi_disk (and scsi_cd) are now
exporting a device on their own, and use an I/O scheduler with an appropriate
DMA resource.
* There are still lots of TODOs, and it can easily panic - don't update if
you intend to demo Haiku.
* scsi_periph now only has an io() function that get an io_operation, instead
of the previous read/write functions, moved preferred CCB size from those
functions into the device registration.
* Changed all scsi_periph files to C++.
* scsi_cd ported, too, but untested.
* Removed block_io from image - it will be removed completely soon.
* Temporarily commented an ASSERT() in the ATA bus manager (in case you use
it); it's sometimes triggered by the code now, and I haven't yet looked into
the issue -- doesn't seem to harm, at least.

* Moved devfs from fs/ to device_manager/, and separated the legacy driver
support from it.
* Removed fast_log module.
* There are a couple of (temporary) regressions, though:
- legacy SATA and ISA IDE support is disabled, the drivers haven't been
ported yet.
- The not yet used ATA bus manager hasn't been ported yet, either.
- AHCI changes have not been tested.
- the listdev command has been removed from the build (as it currently
doesn't work anymore).
- device manager generated IDs currently are not freed anymore when a device
node is removed.
- generic drivers can't yet use the new driver architecture.
- simple busses that do not support device types won't work yet.
- legacy driver publishing/unpublishing (ie. what USB needs) has not been
tested, and may be broken.

again.
* Publish /dev/ptmx. Opening it will open a fresh pty master. In
principle /dev/pt/ is obsolete now, but I guess we keep it around for
compatibility with BeOS. Though there shouldn't be many applications
opening a pty, that we might be interested in...
* New ioctls B_IOCTL_GET_TTY_INDEX (returns the tty index) and
B_IOCTL_GRANT_TTY (grants tty slave access rights).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25133 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced IDE_ADAPTER_IS_PRIMARY by IDE_ADAPTER_CHANNEL_INDEX to support more than 2 bus master channels,
and made ide_adapter aware of 3rd and 4th channel when calculating bus master dma address.
Fixed bus master DMA support in legacy_sata driver for tertiary and quaternary channel, channel 3 and 4
were using the DMA engine of primary and secondary channels (that might have destroyed your data).
Use PCI_address_io_mask instead of ~PCI_address_space (no functional change).

actually forgot to commit the changes I made to the ide_adapter...
* the IDE bus master command/status stuff is now used via flags; it's no
bitfield anymore.
* Changed a few constants to upper case.
