[sp] Is it really necessary to mention ARMV7 in the subject line?
     OMAP3 & BeagbeBoard seem sufficient.

[sp] Don't see any mechanism to read these values. Assuming the
     detection mechanism is consistent i.e. no difference due
     to different eeprom etc. etc.

It looks to me looking at the file that mpurate usage is CPU based and 
NOT board based.. maybe you should use the cpu idendity to decide on 
mpurate instead?

I noticed this too.  I just submitted a patch for Overo that sets the
mpurate to the cpu maximum (based on cpu type and version) if the
mpurate environment variable is set to "auto"

This solves an additional issue: with things as they are now, it is
not possible for a user to set the mpurate to a specific value -- it
will always be overwritten.  The scheme above allows the user to set a
specific value or to allow u-boot to set the maximum automatically.

Note that for 36xx my patch sets the max to 720 -- this is because
mainline/linux-omap currently does not support 1000.  We can adjust
that when kernel support for 1000 appears.

My plan was to submit a similar patch for Beagle.

Errr.. that is not completely true[1](ignoring the lack of upstream DVFS 
for OMAP3+) - Here is the explanation for it:

36xx family of silicon comes in 4 variants - the ones that support upto 
600MHz, ones that do 800MHz, ones that do 1GHz and the ones that do 
1.2GHz. the defaults posted upstream enables the least common 
denominator - 300,600MHz and it leaves it to board files to mention if 
they have silicon of additional capability- unfortunately, there is no 
bits that tell the s/w that(for those wondering - yeah s/w folks did try 
to convince h/w folks for those additional bits.. but after a long 
debate never succeeded) :(

Anyway, to put a long story short - if your board file supports 1GHz, 
with upstream OPP layer, you do have the flexibility to enable 1GHz OPP 
- just look at opp_enable[2] usage documentation [3]. I used thermal 
management as an example here, but no reason why we cant use it as 
well.. this way, you can infact support cpufreq if you would like to as 
well.

[sp] 720MHz is not a valid frequency for 36x. It is the highest freq
     for OMAP35x - subject to associated bit set in the silicon.
     600MHz would be be safe for all OMAP35x family processors.

     For 36xx, the freq should be 800MHz (if you don't want 1GHz).

yep, Good catch :) , 720 is not valid either 800/1GHz :(

Thanks for pointing out that I can go up to 800 Mhz.

For the record, on my 3730 based system, using:

Linux version 2.6.36 (steve at build.sakoman.com) (gcc version 4.3.3
(GCC) ) #1 Thu  Nov 4 21:19:18 PDT 2010

The kernel reports the processor as:

OMAP3630 ES1.0 (l2cache iva sgx neon isp 192mhz_clk )

I tried mpurate settings of 720, 800, and 1000.

Though you say it is "not valid", an mpurate setting of 720 is
successful and yields:

Switched to new clocking rate (Crystal/Core/MPU): 26.0/720/359 MHz

An mpurate setting of 800 is successful and yields:

Switched to new clocking rate (Crystal/Core/MPU): 26.0/800/359 MHz

An mpurate setting of 1000 is not successful and yields:

WARNING: at arch/arm/mach-omap2/clock.c:440
omap2_clk_switch_mpurate_at_boot+0x80/0xb4()
clock: dpll1_ck: unable to set MPU rate to 1000: -22

I will resubmit the patch changing to 800 for 36XX/37XX.

Steve

this should be reported to linux-omap for a fix -> unless someone has 
made some assumption in kernel.org that frequency x really means <=x ;) 
might be good to know why if so..
