[PATCH] ARM: OMAP: Add support to Nokia N810 WiMAX

[Jarkko Nikula]

This adds basic booting support and selects CONFIG_MACH_NOKIA_N810 since
most of the HW and configuration are the same in N810 and N810 WiMAX.

Hopefully someone finds a way to keep it running longer than just few
seconds :-)

I forgot to mention that it seems that HS OMAP or something is ceasing
the operation just few seconds after bootup. Initfs gets more scripts
executed but Debian from mtdblock4 hangs just in init.

hmm.. weird, should be transparent to kernel as long as bootloader
does its job, right ?

That is an odd statement.  Are you commenting about an EMU/HS chip resetting during startup?

There is a secure watch dog when needs to be taken care of and if you program it right.  Generally your initial secure driver or stub ppa will take care of this.

Not resetting but the device seems to just stop during the process.
Only idea what came to mind that probably HS OMAP in N810 WiMAX is
causing this.

Secure driver at least was missing in this trial what is indeed found
in our release :-)

This is understandable actually.  Especially if you don't have some kind of reset sequence in your power chip linked up.

For instance on 3430 + T2 you need to add a reset sequence script into T2's internal memory.  If you don't and you have CPUFREQ (dvfs) running, you can reboot at a time when the voltage is to low.  The ROM code expects a nominal (1.2v) voltage at reset time.  So when the DPLL spins up you can lock up and die.

BTW, this also kills the a 'reboot' command which ultimately just does a warm reset sequence with a prcm write.

... actually in 2420 there are also errata around when its safe to issue a prcm based reset, this can also get you depending on your device.  This deals with the need to be in bypass at the time of the write.

That would do it.  You need to take care of a couple bits else it won't make it.  This is doubly true on 3430 as your full or stub security driver needs to do a bit more.
