      powerpc/85xx: fix various PCI node compatible strings · 14bdc913
      由 Timur Tabi 提交于 
      Fix and/or improve the compatible strings of the PCI device tree nodes for
some Freescale SOCs.  This fixes some issues and improves consistency among
the SOCs.

Specifically:

1) The P1022 has a v1 PCIe controller, so the compatible property should just
say "fsl,mpc8548-pcie".  U-Boot does not look for "fsl,p1022-pcie", so it
wasn't fixing up the node.

2) The P4080 has a v2.1 PCIe controller, so add that version-specific string
to the device tree.  Update the kernel to also look for that string.
Currently, the kernel looks for "fsl,p4080-pcie" specifically, but
eventually that check should be deleted.

3) The P1010 device tree claims compatibility with v2.2 and v2.3, but that's
redundant.  No other device tree does this.  Remove the v2.2 string.

4) The kernel looks for both "fsl,p1023-pcie" and "fsl,qoriq-pcie-v2.2",
even though the P1023 device trees has always included both strings.  Remove
the search for "fsl,p1023-pcie".

      powerpc/85xx: describe the PAMU topology in the device tree · 0408753f
      由 Timur Tabi 提交于 
      The PAMU caches use the LIODNs to determine which cache lines hold the
entries for the corresponding LIODs.  The LIODNs must therefore be
carefully assigned to avoid cache thrashing -- two active LIODs with
LIODNs that put them in the same cache line.

Currently, LIODNs are statically assigned by U-Boot, but this has
limitations.  LIODNs are assigned even for devices that may be disabled
or unused by the kernel.  Static assignments also do not allow for device
drivers which may know which LIODs can be used simultaneously.  In
other words, we really should assign LIODNs dynamically in Linux.

To do that, we need to describe the PAMU device and cache topologies in
the device trees.

      powerpc/85xx: add alternate dts file for sbc8548 boot via SODIMM · dcc8722a
      由 Paul Gortmaker 提交于 
      By moving the two JP12 jumpers 90 degrees, and switching the
setting of SW2.8, the sbc8548 can be configured to boot off
the alternate 64MB SODIMM, which when populated with u-boot
can be a handy recovery option, in case the u-boot in the
8MB soldered on flash gets corrupted.  Here we add an alternate
dts file to match that configuration.

To better highlight the differences, the output from the u-boot
"fli" command is shown for the normal configuration and then
the alternate configuration.

      powerpc/85xx: update sbc8548 flash information to match recent u-boot · 7e83f2ad
      由 Paul Gortmaker 提交于 
      The original memory map for the sbc8548 had the 64MB SODIMM flash
device misaligned by 8MB to allow a window of address space for
the soldered on 8MB device -- i.e.

 start           end             CS<n>   width   Desc.
 ----------------------------------------------------------
 fb80_0000       ff7f_ffff       CS6     32      SODIMM flash (64MB)
 ff80_0000       ffff_ffff       CS0     8       Boot flash (8MB)

However, if we want to change the configuration so that it boots
off the 64MB flash, it is in turn then aligned with a 64MB boundary,
starting at fc00_0000 (and the 8MB @ fb80_0000 -> fbff_ffff).

This makes for complicated updates, since what is the beginning
of the physical device is 8MB into its address space in the default
configuration shown above.

This issue was fixed as of u-boot commit 3fd673cf363bc86ed42eff713d4
("sbc8548: relocate 64MB user flash to sane boundary") -- in which
the SODIMM was mapped to ec00_0000 (natively aligned under efff_ffff)
and so when JP12/SW2.8 are switched, it will be a a simple 0xec --> 0xfc
mapping between the two instances.

Here we make the associated changes in the localbus flash memory
map in the dts file:  indicating the 64MB device starts at ec00_0000
and that the tail end of the 64MB device (last 2 sectors) can contain
a bootloader image.

The partitions for both flash devices get a clean-up; there were
non-meaningful assignments in there that probably originated from
the MPC8548CDS on which the file was based on.  Now there is just
the categorization of free space and bootloader images.

      powerpc/85xx: split sbc8548 dts file into pre and post chunks · d1cf1c7d
      由 Paul Gortmaker 提交于 
      Updates to u-boot allow this board to boot off of either
the 8MB soldered on flash, or the 64MB SODIMM flash.

This is achieved by changing JP12 and SW2.8 which in turn
swaps which flash device appears on /CS0 and /CS6 respectively.

Since the flash devices are not the same size, this also
changes the MTD memory map layout on the local bus.

Here we split the common chunks out into a pre and post
include, so they can be reused by an upcoming "alternative
boot" dts file; leaving only the local bus chunk behind.

No content changes are made at this point - it is just purely
the move to using include files.

6) Two USB ports
7) One PCIe x4 slot
8) DVI video connector
9) Audio input and output jacks, powered by a Wolfson WM8960 codec.

Unlike the P1022DS, the P1022RDK does not have any localbus devices,
presumably because of the localbus / DIU multiplexing restriction of
the P1022 SOC.

      powerpc/85xx: remove P1020RDB and P2020RDB CAMP device trees · b05193c4
      由 Timur Tabi 提交于 
      We only need two examples of CAMP device trees in the upstream kernel.

Co-operative Asymmetric Multi-Processing (CAMP) is a technique where two
or more operating systems (typically multiple copies of the same Linux
kernel) are loaded into memory, and each kernel is given a subset of the
available cores to execute on.  For example, on a four-core system, one
kernel runs on cores 0 and 1, and the other runs on cores 2 and 3.

The devices are also partitioned among the operating systems, and this is
done with customized device trees.  Each kernel gets its own device tree
that has only the devices that it should know about.

Unfortunately, this approach is very hackish.  The kernels are trusted to
only access devices in their respective device trees, and the partitioning
only works for devices that can be handled.  Crafting the device trees is a
tricky process, and getting U-Boot to load and start all kernels is
cumbersome.

But most importantly, each CAMP setup is very application-specific, since
the actual partitioning of resources is done in the DTS by the system
designer.  Therefore, it doesn't make a lot of sense to have a lot of CAMP
device trees, since we only expect them to be used as examples.
