* QLogic ISP2200 and ISP2300 Linux Driver Revision List File.
*
********************************************************************
*
* Revision History
*
* Rev 8.00.00b8 December 5, 2003 AV
* - Instruct mid-layer to perform initial scan.
*
* Rev 8.00.00b7 December 5, 2003 AV
* - Resync with Linux Kernel 2.6.0-test11.
* - Add basic NVRAM parser (extras/qla_nvr).
*
* Rev 8.00.00b7-pre11 December 3, 2003 AV
* - Sanitize the scsi_qla_host structure:
* - Purge unused elements.
* - Reorganize high-priority members (cache coherency).
* - Add support for NVRAM access via a sysfs binary attribute:
* - Consolidate semaphore locking access.
* - Fix more PCI posting issues.
* - Add extras directory for dump/NVRAM tools.
* - Remove unused qla_vendor.c file.
*
* Rev 8.00.00b7-pre11 November 26, 2003 DG/AV
* - Merge several patches from Christoph Hellwig [hch@lst.de]:
* - in Linux 2.6 both pci and the scsi layer use the generic
* dma direction bits, use them directly instead of the scsi
* and pci variants and the (noop) conversion routines.
* - Fix _IOXX_BAD() usage for external IOCTL interface.
* - Use atomic construct for HA loop_state member.
* - Add generic model description text for HBA types.
*
* Rev 8.00.00b7-pre5 November 17, 2003 AV
* - Merge several patches from Christoph Hellwig [hch@lst.de]:
* - patch to split the driver into a common qla2xxx.ko and a
* qla2?00.ko for each HBA type - the latter modules are
* only very small wrappers, mostly for the firmware
* images, all the meat is in the common qla2xxx.ko.
* - make the failover code optional.
* - kill useless lock_kernel in dpc thread startup.
* - no need for modversions hacks in 2.6 (or 2.4).
* - kill qla2x00_register_with_Linux.
* - simplify EH code, cmd or it's hostdata can't be NULL, no
* need to search whether the host it's ours, the midlayer
* makes sure it won't call into a driver for some else
* host.
* - Merge several patches from Jes Sorensen
* [jes@wildopensource.com]:
* - Call qla2x00_config_dma_addressing() before performing
* any consistent allocations. This is required since the
* dma mask settings will affect the memory
* pci_alloc_consistent() will return.
* - Call pci_set_consistent_dma_mask() to allow for 64 bit
* consistent allocations, required on some platforms such
* as the SN2.
* - Wait 20 usecs (not sure how long is really necessary,
* but this seems safe) after setting CSR_ISP_SOFT_RESET in
* the ctrl_status register as the card doesn't respond to
* PCI reads while in reset state. This causes a machine
* check on some architectures.
* - Flush PCI writes before calling udelay() to ensure the
* write is not sitting idle in-flight for a while before
* hitting the hardware.
* - Include linux/vmalloc.h in qla_os.c since it uses
* vmalloc().
* - Use auto-negotiate link speed when using default
* parameters rather than NVRAM settings. Disable NVRAM
* reading on SN2 since it's not possible to execute the
* HBA's BIOS on an SN2. I suggest doing something similar
* for all architectures that do not provide x86 BIOS
* emulation.
* - Clean-up slab-cache allocations:
* - locking.
* - mempool allocations in case of low-memory situations.
* - Fallback to GA_NXT scan if GID_PT call returns more than
* MAX_FIBRE_DEVICES.
* - Preserve iterating port ID across GA_NXT calls in
* qla2x00_find_all_fabric_devs().
* - Pre-calculate ASCII firmware dump length as to not incur the
* cost-to-calculate at each invocation of a read().
*
* Rev 8.00.00b6 November 4, 2003 AV
* - Add new 2300 TPX firmware (3.02.18).
*
* Rev 8.00.00b6-pre25 October 20, 2003 RA/AV
* - Resync with Linux Kernel 2.6.0-test9.
* - Rework firmware dump process:
* - Use binary attribute within sysfs tree.
* - Add user-space tool (gdump.sh) to retrieve formatted
* buffer.
* - Add ISP2100 support.
* - Use a slab cache for SRB allocations to reduce memory
* pressure.
* - Initial conversion of driver logging methods to a new
* qla_printk() function which uses dev_printk (Daniel
* Stekloff, IBM).
* - Further reduce stack usage in qla2x00_configure_local_loop()
* and qla2x00_find_all_fabric_devs().
* - Separate port state used for routing of I/O's from port
* mgmt-login retry etc.
*
* Rev 8.00.00b6-pre19 October 13, 2003 AV
* - Resync with Linux Kernel 2.6.0-test7-bk5.

* - reduce scan time during 'port' RSCN events by only
* querying specified port ids.
* - Available on ISP23xx cards only.
* - Increase maximum number of recognizable targets from 256
* to 512.
* - Backend changes were previously added to support TPX
* (2K logins) firmware. Mid-layer can now scan for targets
* (H, B, T, L) where 512 < T >= 0.
* - Remove IP support from driver.
* - Switch firmware types from IP->TP for ISP22xx and
* IPX->TPX for ISP23xx cards.

* layer requires access to this lun for discovery to occur.
* - General sanitizing:
* - Add generic firmware option definitions.
* - Generalize retrieval/update of firmware options.
* - Fix compile errors which occur with extended debug.
* - Handle failure cases for scsi_add_host() and

* - Pass the complete loop_id, not the masked (0xff) value
* while issuing mailbox commands (qla_mbx.c/qla_fo.c/
* qla_iocb.c/qla_init.c).
* - Properly handle zero-length return status for an RLC CDB.
* - Create an fclun_t structure for 'disconnected' luns,
* peripheral-qualifier of 001b.
* - Remove unused LIP-sequence register access during AE 8010.
