[PATCH] ARM: OMAP2: use early init hook

[PATCH] ARM: OMAP2: use early init hook

[Russell King - ARM Linux]

Move non-mapping and non-irq initialization code out of .map_io and
.init_irq respectively into the new init_early hook.

Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

I think I've updated this patch correctly for the new platforms merged
into mainline.

Please ensure that new platforms merged after this patch also use the
new structure, and note that the initializers should be listed in the
following order:

	.fixup
	.reserve
	.map_io
	.init_early
	.init_irq
	.timer
	.init_machine

This is the order in which they are called, so it helps to make sense
when reading the board level code if they're arranged in called order.

[PATCH] ARM: OMAP2: use early init hook

[Russell King - ARM Linux]

Move non-mapping and non-irq initialization code out of .map_io and
.init_irq respectively into the new init_early hook.

Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
---
I think I've updated this patch correctly for the new platforms merged
into mainline.

Please ensure that new platforms merged after this patch also use the
new structure, and note that the initializers should be listed in the
following order:

	.fixup
	.reserve
	.map_io
	.init_early
	.init_irq
	.timer
	.init_machine

This is the order in which they are called, so it helps to make sense
when reading the board level code if they're arranged in called order.

Grr, this breaks on OMAP because some of this stuff wants to do ioremap()
and therefore wants the kmem allocators initialized.  That's rather
annoying...

So far tested on zoom3 only, but the following gets it booting
on top of your patch.

Want to take this one into your series?  

Meanwhile, I'll add these both into our omap-testing branch
for some more testing.

To me it seems _find_mpu_rt_base should be moved to omap_hwmod_late_init
as we don't want to have a static mapping for everything. AFAIK the
oh->_mpu_rt_va should not be needed early.

Any comments on that Paul? See also the two patches I'll post as a reply
to this thread make omap_hwmod_late_init a core_initcall.

The issue for omap4 still needs to be sorted out. And then we can 
see which omap initcalls really need to be core_initcalls.

Tony

[PATCH] omap2+: Fix omap_serial_early_init to work with init_early hook

[Tony Lindgren]

The new init_early hook happens at the end of setup_arch,
which is too early for kzalloc. However, there's no need
to call omap_serial_early_init that early, so fix this
by setting it up as a core_initcall.

Does mx stuff do non-irq setup or non-map_io stuff in those callbacks?

the map_io callbacks (e.g. mx27_map_io) setup the infrastructure for
cpu_is_xyz and arch_reset.

[PATCH 1/4] ARM: imx: use .init_early to initialize cpu type and reset address

[Uwe Kleine-König]

This used to be done in .map_io which is supposed to only setup the
memory mapping.

[PATCH 2/4] ARM: mx3: use .init_early to initialize cpu type, reset address and iomuxer

[Uwe Kleine-König]

This used to be done in .map_io which is supposed to only setup the
memory mapping.

Russell, I'll queue your patch for the upcoming merge window into
devel-early-init branch along with my changes.

Will also post one more clean-up patch.

[PATCH] omap: Move omap2_check_revision and omap_sram_init out of map_io

[Tony Lindgren]

With the early init changes we just want to map IO in map_io.
Both omap2_check_revision and omap_sram_init can be moved to
happen later in omap2_init_common_infrastructure.

Note that now we can now remove _omap2_map_common_io and remove
the extra flushes too as devicemaps_init will take care of it.

Hmm this one seems to need a bit more work, won't work on 2420.

That's because calling iotable_init after bootmem_init will skip
calling arm_bootmem_init and the new memblock_region we never
call reserve_bootmem on the new entry. So let's skip this for now.

If we want to do SoC detection and SRAM init later during the
boot, we'd have to allocate SRAM the same way as dma-mapping
and ioremap code does.

Tony
