This patch is based on the following patches:
- [U-Boot,v2] arm, am33xx: move rtc32k_enable() to common place
http://patchwork.ozlabs.org/patch/248908/
- [U-Boot] arm, am33xx: move uart soft reset code to common place
http://patchwork.ozlabs.org/patch/248508/
These two apply best to u-boot-ti, and with them this patch doesn't
apply cleanly. Please sort that out.
I based my patches on u-boot ... I look at this ..
The following adds moving ti814x_evm into the mix and I've sent Matt
some binaries to give a whirl to test on the board:
[...]
/*
* Basic board specific setup. Pinmux has been handled already.
Please fold into v2

Ok, thanks!
There's a minor bug in what I posted, however. ti814x needs timer_init
called _before_ pll_init() as setting the sata clocks (which are shared
with other periphrals that we do enable right now) needs udelay(50) to
settle as we go along. That also needs to be commented in the code as I
had to think about it for a bit to recall exactly what was going on.
Do you have an update here for me?
We can have a timer_init for am33xx boards also. It doesn't harm.
So keep timer_init in your common s_init
BTW:
I just realized that I have on one of the three boards a problem,
that in spl code calling the rtc32k_enable() crashes ... which
votes against moving this to a common place ... I haveno real idea
why ... did you heard from such a behaviour? Is there some am335x
soc, which differs from the others?
On which board it is giving a problem?
Did you make sure clocks for rtc are enabled?
I am making a cleanup series for am33xx boards. If you don't mind can I
take this
patch as part of my series.
Thanks and regards,
Lokesh
You aren't using a different clock crystal rate than the reference
platforms, are you? I know that's a problem that needs solving still.
I am prospecting, whats going on here ... but have no real idea,
why it is not possible to write this registers ... if writing this
registers, cpu hang ...
But I want to have a common function here ... maybe it is OK to make
the rtc32k_enable() call configurable through a define?
Saying "CONFIG_SPL_AM33XX_DO_NOT_ENABLE_RTC32K"
and document in the u-boot README this define, and why it is
necessary?
bye,
Heiko
