Hello everyone, thought I'd chime in on this since I've been chasing similar
issues the last few days with the OMAP5432EVM board.
For reference I have been using:
- Upstream Xen (4.5 compiled with early printk=omap5432)
- Upstream Linux (3.17.x)
- An older u-boot (2013.01) that was included with the TI-OMAP5432SDK that
starts the board correctly in HYP mode
-----------
After checking my fdt before boot as Ian suggested I did notice that there was
an error, apparently introduced by copying the commands in to terminal from a
text file. I resolved this error by transferring those commands into uboot
script and running them that way.
At this point I was still having the same problem Konstantin is currently
having. Going off some previous experience with the Arndale (that's related to
the known issue regarding memory banks, even though that issue is supposed to be
resolved in upstream Xen) I bumped the dom0_mem down to 128MB and was finally
able to some output from Linux as follows, I did not have to move the dom0
bootargs as Ian suggested in his later e-mail to get this output:
...
(XEN) *** Serial input -> DOM0 (type 'CTRL-a' three times to switch input to
Xen)

----------------------
I discovered this behavior is apparently linked to a secure monitor call
(omap_smc1 called out in the stack trace above) in the Linux code located in
$LINUX_SOURCE/arch/arm/mach-omap2/timer.c
The function in question is as follows:
#ifdef CONFIG_SOC_HAS_REALTIME_COUNTER
static unsigned long arch_timer_freq;
void set_cntfreq(void)
{
omap_smc1(OMAP5_DRA7_MON_SET_CNTFRQ_INDEX, arch_timer_freq);
}
#endif
Digging through some recent git logs it appears this line was added to address
some issues with TI's DRA7XX boards. I would assume an smc function would cause
issues running in Xen as Xen is running in HYP mode and the smc call has to be
escalated to SECURE mode?
In any case, for experimentation purposes, I simply commented out the
"omap_smc1" line in that file and recompiled the kernel. At the surface it
didn't seem as though that function had much of an impact on the OMAP5432. This
change did result in the dom0 linux boot getting further but still did not
succeed; output was as follows:

------------------------------------
Still not sure of the cause for this, tried all the simple things, but this card
and kernel will boot straight linux without Xen, so I don't think the card
itself or anything like that is the issue.
One thought was that removing that secure monitor call line messed up something
with the clocking on the board such that it can no longer get consistent
accurate reads from the SD card, but that's just one theory.
This is where I am currently and I am still working on the issue, just thought
I'd throw in this info to see if it gives anyone something to work from. I've
attached the complete uboot/xen/linux logs for both boots to this e-mail if that
helps.
Let me know if I can provide any additional information, thanks for your time.
