+ * This could be entirely merged into hermes.c.
+ *
+ * I'm keeping it separate to minimise the amount of merging between
+ * kernel upgrades. It also means the memory overhead for drivers that
+ * don't need firmware download low.
+ *
+ * This driver:
+ * - is capable of writing to the volatile area of the hermes device
+ * - is currently not capable of writing to non-volatile areas
+ * - provide helpers to identify and update plugin data
+ * - is not capable of interpreting a fw image directly. That is up to
+ * the main card driver.
+ * - deals with Hermes I devices. It can probably be modified to deal
+ * with Hermes II devices

+/* Locking and synchronization:
+ *
+ * The basic principle is that everything is serialized through a
+ * single spinlock, priv->lock. The lock is used in user, bh and irq
+ * context, so when taken outside hardirq context it should always be
+ * taken with interrupts disabled. The lock protects both the
+ * hardware and the struct orinoco_private.
+ *
+ * Another flag, priv->hw_unavailable indicates that the hardware is
+ * unavailable for an extended period of time (e.g. suspended, or in
+ * the middle of a hard reset). This flag is protected by the
+ * spinlock. All code which touches the hardware should check the
+ * flag after taking the lock, and if it is set, give up on whatever
+ * they are doing and drop the lock again. The orinoco_lock()
+ * function handles this (it unlocks and returns -EBUSY if
+ * hw_unavailable is non-zero).

+ *
+ * Here's the general details on how the PLX9052 adapter works:
+ *
+ * - Two PCI I/O address spaces, one 0x80 long which contains the
+ * PLX9052 registers, and one that's 0x40 long mapped to the PCMCIA
+ * slot I/O address space.
+ *
+ * - One PCI memory address space, mapped to the PCMCIA attribute space
+ * (containing the CIS).
+ *
+ * Using the later, you can read through the CIS data to make sure the
+ * card is compatible with the driver. Keep in mind that the PCMCIA
+ * spec specifies the CIS as the lower 8 bits of each word read from
+ * the CIS, so to read the bytes of the CIS, read every other byte
+ * (0,2,4,...). Passing that test, you need to enable the I/O address
+ * space on the PCMCIA card via the PCMCIA COR register. This is the
+ * first byte following the CIS. In my case (which may not have any
+ * relation to what's on the PRISM2 cards), COR was at offset 0x800
+ * within the PCI memory space. Write 0x41 to the COR register to
+ * enable I/O mode and to select level triggered interrupts. To
+ * confirm you actually succeeded, read the COR register back and make
+ * sure it actually got set to 0x41, in case you have an unexpected
+ * card inserted.
+ *
+ * Following that, you can treat the second PCI I/O address space (the
+ * one that's not 0x80 in length) as the PCMCIA I/O space.
+ *
+ * Note that in the Eumitcom's source for their drivers, they register
+ * the interrupt as edge triggered when registering it with the
+ * Windows kernel. I don't recall how to register edge triggered on
+ * Linux (if it can be done at all). But in some experimentation, I
+ * don't see much operational difference between using either
+ * interrupt mode. Don't mess with the interrupt mode in the COR
+ * register though, as the PLX9052 wants level triggers with the way
+ * the serial EEPROM configures it on the WL11000.
+ *
+ * There's some other little quirks related to timing that I bumped
+ * into, but I don't recall right now. Also, there's two variants of
+ * the WL11000 I've seen, revision A1 and T2. These seem to differ
+ * slightly in the timings configured in the wait-state generator in
+ * the PLX9052. There have also been some comments from Eumitcom that
+ * cards shouldn't be hot swapped, apparently due to risk of cooking
+ * the PLX9052. I'm unsure why they believe this, as I can't see
+ * anything in the design that would really cause a problem, except
+ * for crashing drivers not written to expect it. And having developed
+ * drivers for the WL11000, I'd say it's quite tricky to write code
+ * that will successfully deal with a hot unplug. Very odd things
+ * happen on the I/O side of things. But anyway, be warned. Despite
+ * that, I've hot-swapped a number of times during debugging and
+ * driver development for various reasons (stuck WAIT# line after the
+ * radio card's firmware locks up).
