Hi all,
Here are some multiboot improvments for review. These patches
are intended for the 2.6.34 merge window.
Comments and testing would be nice, I've tested them so far
on osk, 770, n800, rx51 and overo.
Regards,
Tony

omap: Clean the serial port defines
omap: Make uncompress code and DEBUG_LL code generic
omap: Remove old DEBUG_LL serial port options
omap: Make get_irqnr_and_base common for mach-omap2 multiboot

This way we don't have conflicts with the defines
with compiling in multiple omaps. Set the addresses
for uarts in struct omap_globals for the early serial
init code.

These are physical addresses instead of virtual addresses.
They get ioremapped in mach-omap[12]/serial.c. So they should
not be void __iomem * in omap_globals.
BTW, we should eventually change everything in omap_globals
to be physical addresses.

Tony

Yep. I see your point.

We did some work for OMAP4 to move most of the things to ioremap
istead of those hardcoded macros.
Let me know when you want to do this clean up. We can do this together.

Great, let's try get some more of that ready for the upcoming

I like that approach.
Refer this part from mach-omap2:
+ serial_platform_data0[0].mapbase = omap2_globals->uart1_phys;
+ serial_platform_data1[0].mapbase = omap2_globals->uart2_phys;
+ serial_platform_data2[0].mapbase = omap2_globals->uart3_phys;

Zoom2/3 kind of boards have external debug Serial port.
For those boards and maybe others, the shift value is 1 and not OMAP_PORT_SHIFT(2).
This solution is not extensible to zoom2/3 boards with external debug board uarts.
How do we address that?

OMAP3630 also has 4 UARTS and this same global is getting used for both 34xx and 36xx.
This is not right.

It would be possible if we had omap1_globals. But we don't have it as
the address space is so similar across all omap1 processors.

OK, thanks for pointing that out. Let's add the shift as a variable
in debug-macro.S, see the next patch in the series.

It should be doable, we need to initialize zoom external uart physical
and virtual address in uncompress.h, and also initialize the shift for
it.

Subject: [PATCH] omap: Clean the serial port defines
This way we don't have conflicts with the defines
with compiling in multiple omaps. Set the addresses
for uarts in struct omap_globals for the early serial
init code.

It would be possible if we had omap1_globals. But we don't have it as
the address space is so similar across all omap1 processors.

OK, thanks for pointing that out. Let's add the shift as a variable
in debug-macro.S, see the next patch in the series.

It should be doable, we need to initialize zoom external uart physical
and virtual address in uncompress.h, and also initialize the shift for
it.

* [PATCH 2/4] omap: Make uncompress code and DEBUG_LL code generic

Define arch_decomp_setup() the same way as some other
architectures do. Use arch_id to configure the debug uart
based on the machine_is by storing it into the uart
scratchpad register for DEBUG_LL code to use.

Define arch_decomp_setup() the same way as some other
architectures do. Use arch_id to configure the debug uart
based on the machine_is by storing it into the uart
scratchpad register for DEBUG_LL code to use.

Did not think of that.. Maybe some addruart_premable solution here would.
Or adding \tmp register for addruart and just do the detection for each
character.

How does doing it per-character help? The code is:
ENTRY(printascii)
addruart r3
b 2f
1: waituart r2, r3
senduart r1, r3
busyuart r2, r3
teq r1, #'\n'
moveq r1, #'\r'
beq 1b
2: teq r0, #0
ldrneb r1, [r0], #1
teqne r1, #0
bne 1b
mov pc, lr
Your wait/send/busy macros are just using the already provided base
address which comes via r3 from addruart. That much is fine.
I'm at a loss to understand why you think moving the address-getting
functionality out of addruart into the individual wait/send/busy
macros is going to help in any way.
Why not do something like this:
.pushsection .data
omap_uart_phys: .word 0
omap_uart_virt: .word 0
.popsection
.macro addruart, rx
...
+ ldreq \rx, =omap_uart_phys @ physical base address
+ ldrne \rx, =omap_uart_virt @ virtual base
ldr \rx, [\rx]
+ cmp \rx, #0 @ is port configured?
+ bne 99f @ already configured
...
?

Sorry, I meant doing the detection each time addruart is run, not
for each character.

Also We may need a:
omap_uart_shift: .word 0
Since shift also varies depending on different omap boards (external debug board shift=1, internal omap has shift=2)
Bingo..I think this was the key solution to the problem.
I had posted long ago similar kind of implementation [1]

Updated patch below using .data. This assumes getting an additional
tmp register passed to addruart as in the patch I posted earlier.

OK, I've added that too, but for mach-omap2 only. I've also
added an experimental zoom2/3 support.
Care to take try it out and see what happens on a zoom?

Yeah hopefully we're pretty close to better DEBUG_LL support
for omaps now :)
BTW, I've also pushed these patches into a temporary multi-omap
branch in the linux-omap tree:
http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=shortlog;h=refs/heads/multi-omap
I'll update also the entry-macro.S tomorrow.

Tony

Subject: [PATCH] omap: Make uncompress code and DEBUG_LL code generic
Define arch_decomp_setup() the same way as some other
architectures do. Use arch_id to configure the debug uart
based on the machine_is by storing it into the uart
scratchpad register for DEBUG_LL code to use.

Updated patch below using .data. This assumes getting an additional
tmp register passed to addruart as in the patch I posted earlier.

OK, I've added that too, but for mach-omap2 only. I've also
added an experimental zoom2/3 support.
Care to take try it out and see what happens on a zoom?

Yeah hopefully we're pretty close to better DEBUG_LL support
for omaps now :)
BTW, I've also pushed these patches into a temporary multi-omap
branch in the linux-omap tree:
http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=shortlog;h=refs/heads/multi-omap
I'll update also the entry-macro.S tomorrow.

Test on zoom3 failed with multi-omap branch.
Debugging the same, should have a zoom correction patch out today.

Heh OK. I just pushed more updates into the multi-omap branch
if you want to try to boot zoom2/zoom3 using the same .config.
There are still issues with booting 2420 though..

Yes I tried with new branch and zoom2/3 does not work.
Root cause:
There is a very basic issue in low level code.
We are allowed to create only one Physical to Virtual mapping using MACHINE_START() phys_io and io_pg_offst of size 0x100000(1MB).
Now for zoom2/3 we need to do following:
MACHINE_START(OMAP_ZOOM3, "OMAP Zoom3 board")
- .phys_io = 0x48000000,
- .io_pg_offst = ((0xfa000000) >> 18) & 0xfffc,
+ .phys_io = 0x1000000, /*ZOOM_UART_BASE*/
+ .io_pg_offst = ((0xfb000000) >> 18) & 0xfffc, /*ZOOM_UART_VIRT*/
.boot_params = 0x80000100,
.map_io = omap_zoom_map_io,
.init_irq = omap_zoom_init_irq,
This will create mapping:
0x1000000 <-> 0xfb000000 of 1MB
Now that leaves the phy address 0x4800000 omap register mapping, unmapped.
So the code to get scratchpad contents will abort:
arch/arm/mach-omap2/include/mach/debug-macro.S
moveq \rx, #0x48000000 @ physical base address
movne \rx, #0xfa000000 @ virtual base
orr \rx, \rx, #0x0006a000 @ uart1 on omap2/3/4
This seems to be a basic limitation of low level code and I have not clue how to circumvent this.
Thoughts?

Vikram

Right, we really need 0x48000000 mapped :)

Please take a look at arch/arm/kernel/head.S where you can add
the extra mapping early on.
Hmm, I wonder if we cand nowadays do the extra mapping for zoom
external uart in arch/arm/kernel/early_printk.c?
Are you getting anything out of the zoom uart before MMU is
enabled?
To test this you can temporarily break your kernel by commenting
out the start_kernel line in head-common.S. Then the code falls
through to __error_p and prints out a processor error..

Right, we really need 0x48000000 mapped :)

Please take a look at arch/arm/kernel/head.S where you can add
the extra mapping early on.
Hmm, I wonder if we cand nowadays do the extra mapping for zoom
external uart in arch/arm/kernel/early_printk.c?
Are you getting anything out of the zoom uart before MMU is
enabled?
To test this you can temporarily break your kernel by commenting
out the start_kernel line in head-common.S. Then the code falls
through to __error_p and prints out a processor error..

Tony

Works fine, but it add one issue. Looks like we need to add tmp register
into addruart to initially save the omap_uart_phys and omap_uart_virt:
+ /* Store both phys and virt address for the uart */
+98: add \rx, \rx, #0x48000000 @ phys base
+ ldr \tmp, =omap_uart_phys
+ str \rx, [\tmp, #0]
+ sub \rx, \rx, #0x48000000 @ phys base
+ add \rx, \rx, #0xfa000000 @ virt base
+ ldr \tmp, =omap_uart_virt
+ str \rx, [\tmp, #0]
Does the following patch look OK to you, or do you have some other way
in mind for doing it?
Regards,
Tony

Subject: [PATCH] arm: Add \tmp register for addruart and loadsp
Otherwise more complicated uart configuration won't be possible.
We can use r1 for tmp register for both head.S and debug.S.
NOTE: This patch depends on another patch to add the the \tmp register
into all debug-macro.S files. That can be done with:
$ find arch/arm -name debug-macro.S | xargs -n1 -i sed -i \
-e "s/addruart,rx\|addruart, rx/addruart, rx, tmp/" {}

Can you please add add OMAP4 UART3 case as well here using
"OMAP4UART3".

Can you please add add OMAP4 UART3 case as well here using
"OMAP4UART3".
Attached patch fixes UART3 support for OMAP4 on top of your patches. Tested
this on OMAP4430 SDP. You can fold this patch if you like

Thanks will test. And thanks for testing. Note that once the
issues Russell pointed out are solved, we should also easily
be able to support the external uart on Zoom boards for
DEBUG_LL.

UART_SCR -> this is the scratchpad register
UART_OMAP_SCR -> This is TI-only Supplementary control register
You probably confused the two (as rightly so since SCR is same name).
So there is no need to save/restore the UART_SCR register as you have done, see inlined --

No need to save and restore the UART_SCR register.
This never gets used in this function.
What gets used is UART_OMAP_SCR which is OMAP specific supplimantry control register
and not scratchpad.

Just like uart_base is stored in scratchpad,
Somehow the uart_shift also needs to be stored so that boards with different uart_shift requirements can be addressed. Where can we store this another variable?

Since the base addresses are aligned, how about store the shift in the
least-significant 2 bits, and the rest is the base address.

Just to clarify, the uncompress.h code is using the UART_SCR to store the
DEBUG_LL port number based on the machine ID.
The reason this code is not needed is that the earlyprintk code prints
out something already before we get to this code.
If earlyprintk did not print anything before this code, we would need
to save UART_SCR here as the debug serial port gets initialized the first
time something is printed.
Although the code above uses UART_OMAP_SCR and not UART_SCR, it resets
the uart so we lose UART_SCR.
So in any case I've dropped the code above.
Regards,
Tony

These are no longer needed. Note that zoom boards
should now set their own function in uncompress.h
and debug-macro.S for the external UART.

Make get_irqnr_and_base common for mach-omap2 multiboot
Note that this will only work currently for 24xx and 34xx.
The overhead of this should be minimal, it basically adds one
cmp to see if omap_irq_base has been configured already.
If necessary, we can set separate optimized get_irqnr_and_base
for non-multiboot configurations.
Support for 44xx can be added later on for basic multiboot,
and similar patch should be done for mach-omap1/entry-macro.S.

Well there is an overhead of two instructions for every interrupt,
so probably having two version of "get_irqnr_and_base" would be good.

You have no idea where this word will be placed - it could be in the middle
of a read only section, which might really be read only. It might also be
out of reach of the "ldr \base, [pc, #offset]" instructions you're using
below - which is what an "ldr \base, address" instruction really is.

First thing, why not use get_irqnr_preamble to load the base address?
That means you only do all this computation once per group of IRQs
processed.
Secondly, is this really worth the overhead, or can't you move
omap_irq_base into the data section, and have your IRQ initialization
function set the pointer?
You then don't have to make these two tests every time you check for
an interrupt/enter to process interrupts.

Sounds like a good plan. We can have optimized versions for non-multiomap
configurations.

Great, that will make things much nicer.

Here's this patch updated. It should now be actually more optimized for
non-multi-omap configurations as it uses the get_irqnr_preamble :)

Subject: [PATCH] omap2/3: Make get_irqnr_and_base common for mach-omap2 multiboot
Make get_irqnr_and_base common for mach-omap2 multiboot
Note that this will only work currently for 24xx and 34xx.
The overhead of this should be minimal, it basically adds one
cmp to see if omap_irq_base has been configured already.
If necessary, we can set separate optimized get_irqnr_and_base
for non-multiboot configurations.
Support for 44xx can be added later on for basic multiboot,
and similar patch should be done for mach-omap1/entry-macro.S.

Whereas I can see the sense in loading 'base' here directly, I don't see
the point of finding a value for omap_irq_base in assembly code, when you
have to do IRQ initialization in C code. In fact, you're already sorting
this out in omap_init_irq().

Hmm, I guess it's not like that yet, but will be hopefully
soon.
Currently I believe we have CONFIG_ARCH_OMAP2 selected
for CONFIG_ARCH_OMAP3 too..
I have a set of patches that will remove the overlapping
Kconfig options. Basically I'm planning to convert:
CONFIG_ARCH_OMAP1 = arch/arm/mach-omap1
CONFIG_ARCH_OMAP2PLUS = arch/arm/mach-omap2
CONFIG_ARCH_OMAP2 = defined(CONFIG_CPU_OMAP2420) || defined(CONFIG_CPU_OMAP2430)
CONFIG_ARCH_OMAP3 = defined(CONFIG_CPU_OMAP3430) || defined(CONFIG_CPU_OMAP3630)
CONFIG_ARCH_OMAP4 = stays the same
That will get rid of the double meaning for current
CONFIG_ARCH_OMAP2, and get rid of CONFIG_ARCH_OMAP24XX
and CONFIG_ARCH_OMAP34XX. Will post after I've updated
those patches again, hopefully during next week.
Regards,
Tony

CONFIG_ARCH_OMAP3 = defined(CONFIG_CPU_OMAP3430) || defined(CONFIG_CPU_OMAP3630)
CONFIG_ARCH_OMAP4 = stays the same
That will get rid of the double meaning for current
CONFIG_ARCH_OMAP2, and get rid of CONFIG_ARCH_OMAP24XX
and CONFIG_ARCH_OMAP34XX. Will post after I've updated
those patches again, hopefully during next week.

Hmm, never mind, I guess that issue is sorted out already.
So will update the patch accordingly. Other confusing
Kconfig options still remain, see below.

Attached is also an experimental patch to compile in 2420 and 34xx
and the .config I used.
It still fails early during the boot in dmtimer_init, so it's
just for reference in case anybody wants to play with it.
Note that we still have a problem compiling in 2420 and 2430
because of the different clock bases.
Cheers,
Tony

Subject: [PATCH] omap: Multiboot compile fixes to compile in 24xx and 34xx
Allows compiling in 24xx and 34xx. Not yet ready for merging,
some things need to be done nicer.
Currently booting still fails early in omap_dm_timer_init.

Attached is also an experimental patch to compile in 2420 and 34xx
and the .config I used.
It still fails early during the boot in dmtimer_init, so it's
just for reference in case anybody wants to play with it.
Note that we still have a problem compiling in 2420 and 2430
because of the different clock bases.
Cheers,
Tony
