It uses new API from the part.c to work with partition tables.
Update userboot's disk driver to use new API. Note that struct
loader_callbacks_v1 has changed.
that the wrong UART reference clock will be used for a few of the IDs.
It is currently not possible to figure that out because the Linux FTDI
driver detects this run-time and not compile time based on the bcdDevice
field of the USB device descriptor. Some of the ID's in usbdevs are not
sorted according to the product ID value. Please feel free to fix this.

array, similar to what filltxdesc() uses.
This removes the last reference to ds_data in the TX path outside of
debugging statements. These need to be adjusted/fixed.
Tested:
* AR9280 STA/AP with iperf TCP traffic
The existing API only exposes 'seglen' (the current buffer (segment) length)
with the data buffer pointer set in 'ds_data'. This is fine for the legacy
DMA engine but it won't work for the EDMA engines.
The EDMA engine has a significantly different TX descriptor layout.
* The legacy DMA engine had a ds_data pointer at the same offset in the
descriptor for both TX and RX buffers;
* The EDMA engine has no ds_data for RX - the data is DMAed after the
descriptor;
* The EDMA engine has support for 4 TX buffer/segment pairs in the TX
DMA descriptor;
* The EDMA TX completion is in a different FIFO, and the driver will
'link' the status completion entry to a QCU by a "QCU ID".
I don't know why it's just not filled in by the hardware, alas.
So given that, here are the changes:
* Instead of directly fondling 'ds_data' in ath_desc, change the
ath_hal_filltxdesc() to take an array of buffer pointers as well
as segment len pointers;
* The EDMA TX completion status wants a descriptor and queue id.
This (for now) uses bf_state.bfs_txq and will extract the hardware QCU
ID from that.
* .. and this is ugly and wasteful; it should change to just store
the QCU in the bf_state and save 3/7 bytes in the process.
Now, the weird crap:
* The aggregate TX path was using bf_state->bfs_txq for the TXQ, rather than
taking a function argument. I've tidied that up.
* The multicast queue frames get put on a software TXQ and then that is
appended to the hardware CABQ when appropriate. So for now, make sure
that bf_state->bfs_txq points at the CABQ when adding frames to the
multicast queue.
* .. but the multicast queue TX path for now doesn't use the software
queue and instead
(a) directly sets up the descriptor contents at that point;
(b) the frames on the vap->avp_mcastq are then just appended wholesale
to the CABQ.
So for now, I don't have to worry about making the multicast path
work with aggregation or the per-TID software queue. Phew.
What's left to do:
* I need to modify the 11n ath_hal_chaintxdesc() API to do the same.
I'll do that in a subsequent commit.
* Remove bf_state.bfs_txq entirely and store the QCU as appropriate.
* .. then do the runtime "is this going on the right HWQ?" checks using
that, rather than comparing pointer values.
Tested on:
* AR9280 STA/AP
* AR5416 STA/AP
Use the interface number from the USB interface descriptor
like in the other USB serial drivers. These numbers are not
supposed to be different, though in theory they can. Make sure
that the driver then uses the interface number given by the USB
descriptor, and not the logical index of the USB stack.
For the future:
Whenever the term "index" is used in the USB code, it refers to
a number computed by the USB stack.
Whenever the term "number" is used in the USB code, it refers to
a number in a USB descriptor.
