This is the latest set of 8xx/82xx patches; please apply for 2.6.24.
Kumar, sorry if you got this twice, but my mailer was misconfigured last
time, and thus it didn't get to the list.

As suggested by David Gibson, now that we have a separate node
for the baud rate generators, it's better to use the standard
clock-frequency property than a cpm-node-level fsl,brg-frequency
property.
This patch updates existing places where fsl,brg-frequency is
used.

This introduces a new device binding for the CPM and other devices on
these boards. Some of the changes include:
1. Proper namespace scoping for Freescale compatibles and properties.
2. Use compatible rather than things like device_type and model
to determine which particular variant of a device is present.
3. Give the drivers the relevant CPM command word directly, rather than
requiring it to have a lookup table based on device-id, SCC v. SMC, and
CPM version.
4. Specify the CPCR and the usable DPRAM region in the CPM's reg property.
Boards that do not require the legacy bindings should select
CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once
all existing boards are converted and tested, the config option can
become default y to prevent new boards from using the old model. Once
arch/ppc is gone, the config option can be removed altogether.

+ l) Freescale Communications Processor Module
+
+ NOTE: This is an interim binding, and will likely change slightly,
+ as more devices are supported. The QE bindings especially are
+ incomplete.
+
+ i) Root CPM node
+
+ Properties:
+ - compatible : "fsl,cpm1", "fsl,cpm2", or "fsl,qe".
+ - reg : The first resource is a 48-byte region beginning with
+ CPCR. The second is the available general-purpose
+ DPRAM.
+
+ Example:
+ cpm@119c0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ #interrupt-cells = <2>;
+ compatible = "fsl,mpc8272-cpm", "fsl,cpm2";
+ reg = <119c0 30 0 2000>;
+ }
+
+ ii) Properties common to mulitple CPM/QE devices
+
+ - fsl,cpm-command : This value is ORed with the opcode and command flag
+ to specify the device on which a CPM command operates.
+
+ - fsl,cpm-brg : Indicates which baud rate generator the device
+ is associated with. If absent, an unused BRG
+ should be dynamically allocated. If zero, the
+ device uses an external clock rather than a BRG.
+
+ - reg : Unless otherwise specified, the first resource represents the
+ scc/fcc/ucc registers, and the second represents the device's
+ parameter RAM region (if it has one).
+
+ iii) Serial
+
+ Currently defined compatibles:
+ - fsl,cpm1-smc-uart
+ - fsl,cpm2-smc-uart
+ - fsl,cpm1-scc-uart
+ - fsl,cpm2-scc-uart
+ - fsl,qe-uart
+
+ Example:
+
+ serial@11a00 {
+ device_type = "serial";
+ compatible = "fsl,mpc8272-scc-uart",
+ "fsl,cpm2-scc-uart";
+ reg = <11a00 20 8000 100>;
+ interrupts = <28 8>;
+ interrupt-parent = <&PIC>;
+ fsl,cpm-brg = <1>;
+ fsl,cpm-command = <00800000>;
+ };
+
+ iii) Network
+
+ Currently defined compatibles:
+ - fsl,cpm1-scc-enet
+ - fsl,cpm2-scc-enet
+ - fsl,cpm1-fec-enet
+ - fsl,cpm2-fcc-enet (third resource is GFEMR)
+ - fsl,qe-enet
+
+ Example:
+
+ ethernet@11300 {
+ device_type = "network";
+ compatible = "fsl,mpc8272-fcc-enet",
+ "fsl,cpm2-fcc-enet";
+ reg = <11300 20 8400 100 11390 1>;
+ local-mac-address = [ 00 00 00 00 00 00 ];

+ phy-handle = <&PHY0>;
+ linux,network-index = <0>;
+ fsl,cpm-command = <12000300>;
+ };
+
+ iv) MDIO
+
+ Currently defined compatibles:
+ fsl,pq1-fec-mdio (reg is same as first resource of FEC device)
+ fsl,cpm2-mdio-bitbang (reg is port C registers)
+
+ Properties for fsl,cpm2-mdio-bitbang:
+ fsl,mdio-pin : pin of port C controlling mdio data
+ fsl,mdc-pin : pin of port C controlling mdio clock
+
+ Example:
+
+ mdio@10d40 {
+ device_type = "mdio";
+ compatible = "fsl,mpc8272ads-mdio-bitbang",
+ "fsl,mpc8272-mdio-bitbang",

+ #size-cells = <0>;
+ fsl,mdio-pin = <12>;
+ fsl,mdc-pin = <13>;
+ };
+
+ v) Baud Rate Generators
+
+ Currently defined compatibles:
+ fsl,cpm-brg
+ fsl,cpm1-brg
+ fsl,cpm2-brg
+
+ Properties:
+ - reg : There may be an arbitrary number of reg resources; BRG
+ numbers are assigned to these in order.
+ - clock-frequency : Specifies the base frequency driving
+ the BRG.
+
+ Example:
+
+ brg@119f0 {
+ compatible = "fsl,mpc8272-brg",
+ "fsl,cpm2-brg",
+ "fsl,cpm-brg";
+ reg = <119f0 10 115f0 10>;
+ clock-frequency = <d#25000000>;
+ };
+
+ vi) Interrupt Controllers
+
+ Currently defined compatibles:
+ - fsl,cpm1-pic
+ - only one interrupt cell
+ - fsl,pq1-pic
+ - fsl,cpm2-pic
+ - second interrupt cell is level/sense:
+ - 2 is falling edge
+ - 8 is active low
+
+ Example:
+
+ interrupt-controller@10c00 {
+ #interrupt-cells = <2>;
+ interrupt-controller;
+ reg = <10c00 80>;
+ compatible = "mpc8272-pic", "fsl,cpm2-pic";
+ };
+
+ vii) USB (Universal Serial Bus Controller)
+
+ Properties:
+ - compatible : "fsl,cpm1-usb", "fsl,cpm2-usb", "fsl,qe-usb"
+
+ Example:
+ usb@11bc0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,cpm2-usb";
+ reg = <11b60 18 8b00 100>;
+ interrupts = <b 8>;
+ interrupt-parent = <&PIC>;
+ fsl,cpm-command = <2e600000>;

Consensus was reached to put PCI nodes at the root of the tree (and not
under /soc), but the phandle to a control node was rejected in favor of
simply not worrying about /pci/reg overlapping /soc/ranges.
This updates cuboot-82xx to not look for the phandle.

fsl_get_immr() uses /soc/ranges to determine the immr.
mpc885_get_clock() transforms a crystal frequency into a system frequency
according to the PLL register settings.
pq2_get_clocks() does the same as the above for the PowerQUICC II,
except that it produces several different clocks.
The mpc8xx/pq2 set_clocks() functions modify common properties in
the device tree based on the given clock data.
The mpc885/pq2 fixup_clocks() functions call get_clocks(), and
pass the results to set_clocks().

The existing OF glue code was crufty and broken. Rather than fix it,
it has been removed, and the serial driver now talks to the device tree
directly.
The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms
are dropped from arch/ppc (which will hopefully be soon), and existing
arch/powerpc boards that I wasn't able to test on for this patchset get
converted (which should be even sooner).

1. Move CONSISTENT_START on 8xx so that it doesn't overlap the IMMR mapping.
2. The wrong register was being loaded into SPRN_MD_RPN.

1. Keep a global mpc8xx_immr mapping, rather than constantly
creating temporary mappings.
2. Look for new fsl,cpm1 and fsl,cpm1-pic names.
3. Always reset the CPM when not using the udbg console;
this is required in case the firmware initialized a device
that is incompatible with one that the kernel is about to
use.
4. Remove some superfluous casts and header includes.
5. Change a usage of IMAP_ADDR to get_immrbase().
6. Use phys_addr_t, not uint, for dpram_pbase.
7. Various sparse-related fixes, such as __iomem annotations.
8. Remove mpc8xx_show_cpuinfo, which doesn't provide anything
useful beyond the generic cpuinfo handler.
9. Move prototypes for 8xx support functions from board files
to sysdev/commproc.h.

These let board code set up pins and clocks without having to
put magic numbers directly into the registers.
The clock function is mostly duplicated from the cpm2 version;
hopefully this stuff can be merged at some point.

From: Scott Wood @ 2007-09-17 16:57 UTC (permalink / raw)
To: galak; +Cc: linuxppc-dev
The CPU15 erratum on MPC8xx chips can cause incorrect code execution
under certain circumstances, where there is a conditional or indirect
branch in the last word of a page, with a target in the last cache line
of the next page. This patch implements one of the suggested
workarounds, by forcing a TLB miss whenever execution crosses a page
boundary. This is done by invalidating the pages before and after the
one being loaded into the TLB in the ITLB miss handler.

On arch/ppc, Soft_emulate_8xx was used when full math emulation was
turned off to emulate a minimal subset of floating point load/store
instructions, to avoid needing a soft-float toolchain. This function
is called, but not present, on arch/powerpc, causing a build error
if floating point emulation is turned off.
As:
1. soft-float toolchains are now common,
2. partial emulation could mislead someone into thinking they have
a soft-float userspace because things usually work, only to have it
fail when actual FP gets executed under unusual circumstances, and
3. full emulation is still available for those who need to run
non-soft-float userspace,
I'm deleting the call rather than moving Soft_emulate_8xx over to
arch/powerpc.

The 8xx can only support a max of 8M during early boot (it seems a lot of
8xx boards only have 8M so the bug was never triggered), but the early
allocator isn't aware of this. The following change makes it able to run
with larger memory.

It now uses the new CPM binding and the generic pin/clock functions, and
has assorted fixes and cleanup.

This provides a generic way for board code to set up CPM pins, rather
than directly poking magic values into registers.

From: Scott Wood @ 2007-09-17 16:58 UTC (permalink / raw)
To: galak; +Cc: linuxppc-dev
1. PCI and reset are factored out into pq2.c. I renamed them from m82xx
to pq2 because they won't work on the Integrated Host Processor line of
82xx chips (i.e. 8240, 8245, and such).
2. The PCI PIC, which is nominally board-specific, is used on multiple
boards, and thus is used into pq2ads-pci-pic.c.
3. The new CPM binding is used.
4. General cleanup.

Shouldn't you check for "fsl,brg-frequency" here, in case of old
device trees?

What old device trees? fsl,brg-frequency has never hit mainline; it's
only been in Kumar's tree for a week or so.

Can you explain what this isssue is? We're using a 8280 and have had
some PCI busmaster DMA problems, and wonder if it is related.

I'm not sure of the details, just that I get corrupted PCI DMA if I don't
set it.
BTW, if the problems you're seeing include lockups when using PCI DMA,
check out the end of the PCI initialization in
arch/powerpc/boot/cuboot-pq2.c; it requires certain non-default arbiter
settings.

I'm still not in favor of this and think we should move the
Soft_emulate_8xx code over.

Mainly that 8xx has been doing this for a vast number of years and I
see no reason to stop doing it at this point.
While I can see that it might be misleading, clearly 8xx linux users
haven't had issues with it.

Or they haven't said anything. :-P
How about a three-way choice of full emulation, minimal emulation, and no
emulation?

I preferred the split-node method, but as you say, this consensus has
been reached for now.

Hrm. When I said to extract the logic of fixup_mac_addrs(), I meant
to create a new one-address version of the function in devtree.c then
use it both here and in the fixup_mac_addrs() function. Rather than
duplicating it inline here.

Nice, but again, it seems a bit pointless to leave in all the
immr_map() / immr_unmap() pairs now that they do basically nothing.

One step at a time. :-)
Once arch/ppc is gone, I'd like to do some heavier cleanup of the CPM
stuff, including merging with QE. For now, I want to touch code that's
shared between the architectures as little as possible.
