Mapping the parent IRQ will use a virq number which may conflict with
the hardcoded I8259A_IRQ_BASE..I8259A_IRQ_BASE+15 range that the i8259
driver expects to be free. If this occurs then we'll hit errors when
adding the i8259 IRQ domain, since one of its virq numbers will already
be in use.
Avoid this by adding the i8259 domain before mapping the parent IRQ,
such that the i8259 virq numbers become used before the parent interrupt
controller gets a chance to use any of them.

Hello,
Any chance of getting reviews/acks on this & the following 2 patches in the
series so Ralf can take them through the MIPS tree? The lack of these (well,
patches 1 & 2 anyway) blocks applying many of the Malta patches later in the
series.
Thanks,
Paul

The default i8259 polling function (i8259_irq) is nicely generic but is
fairly costly. Platforms often provide an alternative means of polling
for an i8259 interrupt, and when using the i8259 without device tree
have typically just chained its parent interrupt to their own handler
function. In order to allow for platform-specific polling functions to
be used in cases where the driver is probed via device tree, provide an
i8259_set_poll function that accepts a pointer to an alternative poll
function that will override the default.

Set the PCI_BAR0 register in all configurations such that PCI devices
can perform DMA to all of the bottom 2GB of the physical address space.
This is imperfect if we make use of the legacy Malta memory map, but it
is an improvement on the inconsistent values setup before.

Malta boards can have more than 256MB DDR available, but we have
previously only made use of up to 256MB (ie. the DDR accessible via
kseg0) by default, without the user manually specifying mem= kernel
parameters. This patch causes all available DDR, as reported by the
bootloader via the ememsize or memsize environment variables or
optionally on the command line, to be used when possible without the
user needing to manually provide the memory ranges.
Malta now has 2 subtly different memory maps which have to be taken into
account when setting this up. The original memory map (referred to by
the code as v1) has up to 2GB of DDR aliased in both the upper & lower
halves of the 32 bit physical address space, with a 256MB I/O region
obscuring 0x10000000-0x1fffffff only in the lower alias. The revised v2
memory map is flat with up to 4GB DDR starting from 0x0, and the I/O
region obscures 256MB of DDR which becomes inacessible. The memory map
in use is indicated by a register provided by the rocit2 system
controller, which is checked in order to set up the kernels memory
ranges accordingly.

Probe the CPU, GIC & i8259 interrupt controllers present in the Malta
system using device tree. This enables interrupts to be provided to
devices using device tree as they are moved over to being probed using
it.
Since Malta is very configurable it's unknown whether a GIC will be
present at compile time. In order to support both cases the
malta_dt_shim code is added in order to detect whether a GIC is present,
adjusting the DT to route interrupts correctly and nop out the GIC node
if no GIC is found.

Since commit 44a7185c2ae6 ("of/platform: Add common method to populate
default bus") platforms calling of_platform_bus_probe from an initcall
is either a rather unsafe race with of_platform_default_populate_init or
a no-op. The MIPS Malta board needs to probe devices under an ISA bus,
which we do support in the of_busses array but until now haven't
included in of_default_bus_match_table.
Add an "isa" entry to of_default_bus_match_table such that we can just
accept use of of_platform_default_populate_init & remove the
Malta-specific match table in a later patch.

Haven't you also renamed the node?

Hi Sergei,
Yes, strictly speaking I could have been more verbose & elaborated in
the changelog on every aspect of the simple change from "rtc:
mc146818@70" to "rtc@70". I didn't, but as it's obviously clear to you
what changed and it has no effect on either the code or the commit that
would end up in git I don't really see the point of your bringing it up.
Thanks,
Paul

It may be obvious to me (since it was my comment that you addressed here)
but not to others... Perhaps I'm too captious indeed, sorry about that. :-)

Add the DT nodes required to probe the CFI compatible parallel monitor
flash found on the Malta development board, and remove the platform
code that was previously doing it. Delete the now-empty malta-platform.c
file. Adjust the Malta defconfigs that enable MTD & the pflash/CFI
driver to enable CONFIG_MTD_PHYSMAP_OF rather than CONFIG_MTD_PHYSMAP in
order to preserve their behaviour.

Changes in v2:
- Leave malta-platform.o in Makefile
- Move partitions under a partitions node

Make use of the generic syscon-reboot driver to reboot the Malta board,
reducing the amount of platform code it requires.

This has broken reboot support, all I get now is:
reboot: Restarting system
Unable to restart system
Reboot failed -- System halted
at which point I need to issue a serial BREAK to regain control of the
board and get back to YAMON; fortunately the board is wired for that.
See attached config.

This was already reported over here:
https://www.linux-mips.org/archives/linux-mips/2016-10/msg00120.html
These 2 patches fix it:
https://patchwork.linux-mips.org/patch/14395/
https://patchwork.linux-mips.org/patch/14396/
I've asked Ralf if we can get those, along with a few others, in ASAP -
preferrably for -rc3.
Thanks,
Paul

Thanks, good to know and sorry to raise a late alarm then.
As it happens the board I've been fiddling with has been temporarily
sitting idle, so I went ahead and verified that these changes have indeed
removed the regression in my configuration. So you've got a confirmation
from a real Malta hardware user now too (QEMU may have its own quirks).

As these are fixes to a functional regression I also recommend merging
them ASAP.

The arch code will hang the machine with an infinite loop if the board
doesn't provide an impelementation of halt - let it, rather than
duplicating it.

Add a driver which allows powering off the system via an Intel PIIX4
southbridge, by entering the PIIX4 SOff state. This is useful on the
MIPS Malta development board, where it will power down the FPGA based
board until its ON/NMI button is pressed, or the QEMU implementation of
the MIPS Malta board where it will cause QEMU to exit.

Remove the platform code used to power down the system, instead relying
upon the new PIIX4 poweroff driver. This reduces the amount of platform
code required for the Malta board in preparation for allowing it to be
part of a more generic kernel.
