Hmm. Still not happy. Wasn't there some SoC infrastructure added to the
kernel to export this kind of information via sysfs? See:

As Samuel will take the LEDs patch through his tree, I've regenerated
the branch, so:
The following changes since commit 949db153b6466c6f7cad5a427ecea94985927311:

That would be appreciated as I don't have any good answer to provide.
Typically, this patch highlighted problems with bad holding pen
implementations where secondary CPUs would enter the kernel all at the
same time. In that case the kernel was crashing even before displaying
"CPU2: Booted secondary processor".

I *think* it is because in the ARM11MPcore GIC
dist_base + GIC_DIST_TARGET
is RAZ for IT0-IT28. To give it a go you should change code in
gic_cpu_init()
and read (GIC_DIST_TARGET + 0x1c) (where IT29 starts)
if I am not mistaken, since that will return the GIC CPU IF ID of the
reading CPU.
Just guessing, hope it helps,

Uh, I afraid that my light-generating capabilities may be slightly
overestimated, as it was just a logical but lucky guess, really.

I'll try to get the board and reproduce the problem, but I can't promise

Well, for the I/O space, there is no oversizing because either way you
end up with exactly 64KB per root port, right?

Using the Linux allocator for memory resources does sound useful,
so if that requires using the emulated PCI-to-PCI bridges, I guess
it's the best compromise.

I'm sorry about this situation. Unfortunatly the way that such decisions
are made is not always straightforward, and what seems like a good idea
at one point turns out to be a mistake or more complex than anticipated
later. With the description of the first patch set, I did not think
it would be necessary to fake a bridge device and their config space.
What I had guessed you could do was to call pci_scan_root_bus on
each of the ports, and then set up the memory space window for
the bus including all of its child devices.

Well, the patch still looks fine to me. It might be a good idea to
dump out the value of GIC_DIST_TARGET + 0, just in case there's some
version of the GIC which doesn't advertise its CPU mask via that
register (it should, because it corresponds with SGI0..3, and every
spec I have says that it will be implemented if these IRQs are present).
We do know already that there are some implementations out there which
don't conform to these documents...

I wasn't sure if the IMX maintainers had any branch based on the
timer/cleanup branch already. On the off-chance you did, I sent the
patch to you. If you don't, I can resend to the arm-soc maintainers.

Correct I/O space is not an issue, of course. Only the memory windows
are an issue (in terms of quantity of address space used).
That said, the PCI-to-PCI bridge solution doesn't solve the fact that
I/O addresses get assigned even though the driver will most likely use
them. This means that one I/O window is consumed for each PCIe
interface, even though it is not being used in practice. And see I have
10 PCIe interfaces in this SoC, and only 20 windows available globally
(not only for PCIe, but also for NAND, NOR, etc.). But for now, I'd
like to leave this potential problem on the side, and get something
working. If it seems useful to remove this problem later, we'll work on
it.

Yes, that was Jason's original idea when he suggested to use PCI-to-PCI
bridges. And when I did the implementation, it really worked nicely.
And this PCI-to-PCI bridge emulation stuff is really not a big deal,
look at drivers/pci/sw-pci-pci-bridge.c: 185 lines in total, including
10 lines of comment header at the top.

Sure, I understand this. I guess you also understand my slight
frustration when I propose A, I'm told to do B, I propose B, and I'm
then suggested to do A again :-) But I agree, it's part of the
technical discussion, and we can't get it right on the first shot.

But where would I read how much space is needed for the I/O and memory
regions of each bus?

The same problem still exists. According to the TRM, there's at least one
AM335x CLKCTRL register that doesn't have IDLEST bits. So to avoid
reading reserved bits, either this patch or a preceding patch should
mark those hwmods with HWMOD_NO_IDLEST.

Right, okay. This is the bug. GIC_DIST_TARGET+0 can most certainly read
as zeros on MPCore platforms (it's in the MPCore engineering spec).
Only interrupts 29, 30 and 31 read as non-zero and return the corresponding
CPU mask. Interrupts 0-28 read as zero.
However, this is further complicated: in later GIC revisions, it says that
these registers can return 0 for unimplemented interrupts. Are interrupts
29-31 always guaranteed to be implemented? I don't think we can rely on
that.
What we could do is scan interrupts 0-31 for a non-zero value. If they're
all zero, we should complain. Otherwise, we use the first non-zero value
we find and validate it for a single bit set.

Why you don't implement it ?
If you don't implement it, I believe you should add a warning in order to catch
it when used with lpm devices.

That's because IT28 read as zero as well, so using 0x1c does not work.
See Russell's reply, basically we need to scan first 32 IRQs and use
the first non-zero value to init the map.

This seems very strange.
I'm going to reply to this email again with how the patch should look.

* [PATCH 0/5] ARM: OMAP2+: System timer updates
From: Jon Hunter @ 2013-01-30 17:04 UTC (permalink / raw)
To: linux-arm-kernel
This series consists mainly of clean-ups for clockevents and
clocksource timers on OMAP2+ devices. The most significant change
in functionality comes from the 5th patch which is changing the
selection of the clocksource timer for OMAP3 and AM335x devices
when gptimers are used for clocksource. This change came about from
Vaibhav Bedia's series for AM335x [1]. See patch for more details on
the exact nature of the change.
Boot tested with and without device-tree on OMAP2420 H4,
OMAP3430 SDP, OMAP3430 Beagle Board, OMAP4430 SDP and
AM335x EVM (AM335x only supports device-tree boot).
This series is based upon ARM-SoC next branch.

* [PATCH 1/5] ARM: OMAP2+: Display correct system timer name
From: Jon Hunter @ 2013-01-30 17:04 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359565471-30721-1-git-send-email-jon-hunter@ti.com>
Currently on boot, when displaying the name of the gptimer used for
clockevents and clocksource timers, the timer ID is shown. However,
when booting with device-tree, the timer ID is not used to select a
gptimer but a timer property. Hence, it is possible that the timer
selected when booting with device-tree does not match the ID shown.
Therefore, instead display the HWMOD name of the gptimer and use
the HWMOD name as the name of clockevent and clocksource timer (if a
gptimer is used).

* [PATCH 2/5] ARM: OMAP2+: Remove hard-coded test on timer ID
From: Jon Hunter @ 2013-01-30 17:04 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359565471-30721-1-git-send-email-jon-hunter@ti.com>
Currently, when configuring the clock-events and clock-source timers
for OMAP2+ devices, we check whether the timer ID is 12 before
attempting to set the parent clock for the timer.
This test was added for OMAP3 general purpose devices (no security
features enabled) that a 12th timer available but unlike the other
timers only has a single functional clock source. Calling
clk_set_parent() for this 12th timer would always return an error
because there is only one choice for a parent clock. Therefore,
this hard-coded timer ID test was added.
To avoid this timer ID test, simply check to see if the timer's current
parent clock is the desired parent clock and only call clk_set_parent()
if this is not the case.

To: linux-arm-kernel
In-Reply-To: <1359565471-30721-1-git-send-email-jon-hunter@ti.com>
In commit c59b537 (ARM: OMAP2+: Simplify dmtimer clock aliases), new
clock aliases for dmtimers were added to simplify the code. These clock
aliases can also be used when configuring the system timers and allow us
to remove the current definitions, simplifying the code.

* [PATCH 4/5] ARM: OMAP2+: Simplify system timers definitions
From: Jon Hunter @ 2013-01-30 17:04 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359565471-30721-1-git-send-email-jon-hunter@ti.com>
There is a lot of redundancy in the definitions for the various system
timers for OMAP2+ devices. For example, the omap3_am33xx_gptimer_timer_init()
function is the same as the omap3_gp_gptimer_timer_init() function and the
function omap2_sync32k_timer_init() can be re-used for OMAP4/5 devices.
Therefore, consolidate the definitions to simplify the code.

* [PATCH 5/5] ARM: OMAP3: Update clocksource timer selection
From: Jon Hunter @ 2013-01-30 17:04 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359565471-30721-1-git-send-email-jon-hunter@ti.com>
When booting with device-tree for OMAP3 and AM335x devices and a gptimer
is used as the clocksource (which is always the case for AM335x), a
gptimer located in a power domain that is not always-on is selected.
Ideally we should use a gptimer located in a power domain that is always
on (such as the wake-up domain) so that time can be maintained during a
kernel suspend without keeping on additional power domains unnecessarily.
In order to fix this so that we can select a gptimer located in a power
domain that is always-on, the following changes were made ...
1. Currently, only when selecting a gptimer to use for a clockevent
timer, do we pass a timer property that can be used to select a
specific gptimer. Change this so that we can pass a property when
selecting a gptimer to use for a clocksource timer too.
2. Currently, when selecting either a gptimer to use for a clockevent
timer or a clocksource timer and no timer property is passed, then
the first available timer is selected regardless of the properties
it has. Change this so that if no properties are passed, then a timer
that does not have additional features (such as always-on, dsp-irq,
pwm, and secure) is selected.
Please note that using a gptimer for both clocksource and clockevents
can have a system power impact during idle. The reason being is that
OMAP and AMxxx devices typically only have one gptimer in a power domain
that is always-on. Therefore when the kernel is idle both the clocksource
and clockevent timers will be active and this will keep additional power
domains on. During kernel suspend, only the clocksource timer is active
and therefore, it is better to use a gptimer in a power domain that is
always-on for clocksource.

* [PATCH] mmc: mmc_spi: Fix return value evaluation of irq_of_parse_and_map()
From: Roland Stigge @ 2013-01-30 17:05 UTC (permalink / raw)
To: linux-arm-kernel
When irq_of_parse_and_map() returns an error, it does as zero. But in
mmc_spi_get_pdata(), the error return case is compared against NO_IRQ. This
might work where NO_IRQ is zero (defaults to zero when undefined, as on MIPS)
but not where NO_IRQ is sth. different, e.g. on ARM, where it is -1.
This patch changes to comparison with 0 which is the error return value of
irq_of_parse_and_map().
Tested on ARM that mmc_spi is working now.
