      scsi/atari_scsi: Don't select CONFIG_NVRAM · 83d2aed4
      Finn Thain authored 
      
On powerpc, setting CONFIG_NVRAM=n builds a kernel with no NVRAM support.
Setting CONFIG_NVRAM=m enables the /dev/nvram misc device module without
enabling NVRAM support in drivers. Setting CONFIG_NVRAM=y enables the
misc device (built-in) and also enables NVRAM support in drivers.

m68k shares the valkyriefb driver with powerpc, and since that driver uses
NVRAM, it is affected by CONFIG_ATARI_SCSI, because of the use of
"select NVRAM". We can avoid the "select" here, but drivers still have
to interpret the CONFIG_NVRAM symbol consistently regardless of platform.

In this patch and the subsequent fbdev driver patch, the convention is
adopted across all relevant platforms whereby NVRAM functionality gets
enabled in a given device driver when the nvram misc device is built-in
or when both drivers are modules.

      scsi: zorro_esp: New driver for Amiga Zorro NCR53C9x boards · 3109e5ae
      Michael Schmitz authored 
      
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.

      block: fix CDROM dependency on BLK_DEV · c091fbe9
      Arnd Bergmann authored 
      
After the cdrom cleanup, I get randconfig warnings for some configurations:

warning: (BLK_DEV_IDECD && BLK_DEV_SR) selects CDROM which has unmet direct dependencies (BLK_DEV)

This adds an explicit BLK_DEV dependency for both drivers. The other
drivers that select 'CDROM' already have this and don't need a change.

      scsi: scsi_transport_sas: select BLK_DEV_BSGLIB · 580b71e9
      Arnd Bergmann authored 
      
Without CONFIG_BLK_DEV_BSGLIB, we get a link error here:

drivers/scsi/scsi_transport_sas.o: In function `sas_bsg_initialize':
scsi_transport_sas.c:(.text+0xcc0): undefined reference to `bsg_setup_queue'
scsi_transport_sas.c:(.text+0xd10): undefined reference to `bsg_setup_queue'
drivers/scsi/scsi_transport_sas.o: In function `sas_smp_dispatch':
scsi_transport_sas.c:(.text+0xe8c): undefined reference to `bsg_job_done'

This modifies the Kconfig 'select' statement accordingly, and matching
what we do for the other two scsi_transport implementations that use
bsglib.

      scsi: lpfc: Finalize Kconfig options for nvme · 7d708033
      James Smart authored 
      
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.
