[PATCH v3 0/3] Support for OMAP3 Zoom2 board

[PATCH v3 0/3] Support for OMAP3 Zoom2 board

[Mikkel Christensen]

The following patch series adds support for Zoom2 board.
This is a new version made after comments from Kevin Hilman.

An external debug board is included for console and LAN.

For details refer to this site:
http://www.logicpd.com/products/development-kits/texas-instruments-zoom%E2%84%A2-omap34x-ii-mdp

Future work:
 - SMSC911x NFS mount problem
 - Low level debug uart need to use debug board

I assume the uncompress.h and DEBUG_LL patches for UART are coming
next as they are also required to boot.

Please just move all the related functions to board-zoom2.c. I don't see any
reason to have a separate file for the debugboard features. The runtime detection
should do the trick.

Also, the arch_initcall() above is wrong, it runs for all the boards and
platforms compiled in even if they are not zoom2 boards.

Other than, looks OK to me, so we might be able to get this into mainline
this merge window.

Regards,

Tony

Two reasons for keeping a separate debug board.
a) debug board is detachable in h/w and hence we thought its better to keep the s/w also that way
The quart chip on debug bard is a quard-uart and can support 4 different console outputs.
All those we thought of adding in future.

b) we took reference from board-rx51-peripherals.c wherein some parts of the board file can be moved out to a new file

If you still think we need to merge, then let us know. 
We are open to suggestions/changes.

Well those you can easily optimize out by not compiling in those devices.

Well the reason for separate board-*-peripheral-whatever.c files is that
they're intended to be shared with other board-*.c files. Currently n8x0
and rx51 share devices. In general, we should try to do generic platform
init files, like gpmc-onenand.c and gpmc-smc91x.c.

Then I see need for gpmc-sdp-flash.c that's shared between 2430 and 3430 sdp
at least.

So yeah, for zoom2, I'd rather see just board-zoom2.c for now. But if you
create some other board that uses the same debug board functions, then
there could be a separate zoom-debugboard.c.

Regards,

Tony

Yes. There is next generation of zoom boards that will re-use the Debug board.
That way the debug board file will get re-used.

OK, how about rename it to something that makes sense as a name for
multiple zoom like boards and resubmit.

Also the arch_initcall() issue below still needs fixing.

I am planning on renaming debug board zoom2 file to board-zoom-debugboard.c
That way it can be used by different Zoom family of boards.

I have cleaned the issue by making the debug_board_init call as late_initcall().

There is a dependency on serial.c file and hence the need for arch_init/late_init calls.

platform_device_register() should happen for serial.c file (8250) for the omap uarts first and this should be followed by platform_device_register() for the quard uart on debug board.

So there is a dependency on order of registration of platform device for the same 8250 driver.

If you ack, then I can post the patches with the changes.

Well you still cannot have it as a late_initcall(), you should just call the
function from board-zoom2.c. Otherwise it will run for all the boards.

The problem is that serial.c: platform_device_register() for UART1/2/3 happens as arch_init().

We want that Quard/Dbg-board Uart console to appear as UART4(ttyS3) and so the platform_device_register() has to happen after the arch_init() call from serial.c

If we put the dbg-board init in .init_machine   = omap_zoom2_init() function, then this gets called first before the serial.c:arch_init() and assigns ttyS0(UART0) to the debug board uart.

This is not what we want to do.

Way not execute the debug board function for other boards could be to put it under 
#ifdef CONFIG_MACH_OMAP_ZOOM2 

static int __init omap_zoom2_debugboard_init(void)
{
#ifdef CONFIG_MACH_OMAP_ZOOM2
        if (!omap_zoom2_debugboard_detect())
                return 0;

        zoom2_init_smsc911x();
        zoom2_init_quaduart();
        return platform_add_devices(zoom2_devices, ARRAY_SIZE(zoom2_devices));
#endif
}
late_initcall(omap_zoom2_debugboard_init);


The registration order of the UARTS with 8250 driver is all the reason we have to do this _initcall()

Hmm, OK. That sounds like a bug that's from some older code. We should probably
just do the platform_device_register in omap_serial_init(), then you can call
your zoom_debug_init() after omap_serial_init().

Care to do a separate patch to get rid of omap_init in mach-omap2/serial.c, and do
the registration in omap_serial_init()?

Regards,

Tony

Yes I can do that. I will submit the patch for this change.
Following this I will resubmit Zoom2-board support version4
