Reading throught the new driver, I noticed that this cannot work on
big-endian CPUs, and the old DAC960 had exactly the same behavior.
To document this for the future, add a Kconfig dependency that prevents it
from being included in big-endian kernels. Since the hardware is really
old and we never had a working driver on it for big-endian platforms,
it's unlikely to make a difference to users.

As a temporary measure, the code to implement PIO transfers was

New combined SCSI driver for all ESP based Zorro SCSI boards for m68k Amiga.
Code largely based on board specific parts of the old drivers (blz1230.c,
blz2060.c, cyberstorm.c, cyberstormII.c, fastlane.c which were removed after
the 2.6 kernel series for lack of maintenance) with contributions by Tuomas
Vainikka (TCQ bug tests and workaround) and Finn Thain (TCQ bugfix by use of
PIO in extended message in transfer).
New Kconfig option and Makefile entries for new Amiga Zorro ESP SCSI driver
included in this patch.
Use DMA transfers wherever possible, with board-specific DMA set-up functions
copied from the old driver code. Three byte reselection messages do appear to
cause DMA timeouts. So wire up a PIO transfer routine for these
instead. esp_reselect_with_tag explicitly sets
esp->cmd_block_dma as target address for the message bytes but PIO
requires a virtual address. Substiute kernel virtual address
esp->cmd_block in PIO transfer call if DMA address is esp->cmd_block_dma
and phase is message in.
PIO code taken from mac_esp.c where the reselection timeout issue was debugged
and fixed first, with minor macro and function rename.

Reviewing the result of what was just added for Kconfig, we made a poor
choice. It worked well for full kernel builds, but not so much for how
it would be deployed on a distro.
Here's the final result:
- lpfc will compile in NVME initiator and/or NVME target support based
on whether the kernel has the corresponding subsystem support.
Kconfig is not used to drive this specifically for lpfc.
- There is a module parameter, lpfc_enable_fc4_type, that indicates
whether the ports will do FCP-only or FCP & NVME (NVME-only not yet
possible due to dependency on fc transport). As FCP & NVME divvys up
exchange resources, and given NVME will not be often initially, the
default is changed to FCP only.

Pull SCSI target updates from Nicholas Bellinger:
"The most notable item is IBM virtual SCSI target driver, that was
originally ported to target-core back in 2010 by Tomo-san, and has
been brought forward to v4.x code by Bryant Ly, Michael Cyr and co
over the last months.
Also included are two ORDERED task related bug-fixes Bryant + Michael
found along the way using ibmvscsis with AIX guests, plus a few
miscellaneous target-core + iscsi-target bug-fixes with associated
stable tags"
* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
target: fix spelling mistake: "limitiation" -> "limitation"
target: Fix residual overflow handling in target_complete_cmd_with_length
tcm_fc: set and unset FCP_SPPF_TARG_FCN
iscsi-target: Fix panic when adding second TCP connection to iSCSI session
ibmvscsis: Initial commit of IBM VSCSI Tgt Driver
target: Fix ordered task CHECK_CONDITION early exception handling
target: Fix ordered task target_setup_cmd_from_cdb exception hang
target: Fix max_unmap_lba_count calc overflow
target: Fix race between iscsi-target connection shutdown + ABORT_TASK
target: Fix missing complete during ABORT_TASK + CMD_T_FABRIC_STOP
This driver is a pick up of the old IBM VIO scsi Target Driver
that was started by Nick and Fujita 2-4 years ago.

The driver provides a virtual SCSI device on IBM Power Servers.
This patch contains the fifth version for an initial merge of the
tcm ibmvscsis driver. More information on this driver and config
can be found:

Now it's ready to move the mempool based SG chained allocator code from
SCSI driver to lib/sg_pool.c, which will be compiled only based on a Kconfig
symbol CONFIG_SG_POOL.
SCSI selects CONFIG_SG_POOL.
