[PATCH 2/4] ARM: beaglebone: add helper init script for checking if BBBW

[Marc Reilly]

This adds a check against the eeprom contents to see if the board is a
Beaglebone black wireless. (two bytes at offset 0x12 of eeprom will be
"BW").
If it is, the global board.variant is updated to "boneblackwireless"

[PATCH 4/4] ARM: beaglebone: init MPU speed to 800Mhz

[Marc Reilly]

This sets the core processor speed to 800Mhz (from 500). Doing this helps
speed the boot up a bit until the CPU freq govenor takes over.

This would change behavior for boot scripts that directly boot
instead of setting up variables for bootm to use, but I think
that's acceptable,

Maybe change message to reflect the new reality?

To be honest I didn't consider this .. although I'm not sure what the use case 
for this command would be for that scenario.

Ideally then, there could be two parameters for 'dryrun', one to stop at 
running the script, and one to go through to the call to bootm.
This could also be done using a combination of the 'verbose' and 'dryrun' 
flags ... (somewhat hackish solution)

Sure, I can do this, unless we think the extra parameter should be added to 
the command.

That's the reason the dryrun for bootscripts is aborted before executing
them. Both ways are not really optimal, but I don't want to replace one
suboptimal solution with another.
Maybe we could pass an option to the bootscript so that a script has
the chance to test for that option before booting. That would still
change the behaviour for scripts that don't test for that option, but
at least they could be fixed.

I think it's worth doing this in C code. A good template for this is in
https://git.pengutronix.de/cgit/barebox/tree/arch/arm/boards/skov-imx6/board.c#n435
Here the board compatible is prepended with a more specific variant, for
the BBB this would be "ti,am335x-bone-black-wireless". With this
bootspec could pick the entry with the right devicetree without further
interventions.
