[PATCH] beaglebone: use the am335x_boneblack u-boot configuration

[Alexandre Belloni]

Using the am335x_boneblack configuration for u-boot allows to save the
environment to the emmc. Else, it is not possible to save the
environment at all.

How does this config work on the Beaglebone white?

Perhaps it would be better to let this assignment be soft, i.e.
   UBOOT_MACHINE ?= "am335x_boneblack"

That way, either choice would be possible.

I didn't test but I don't think it will change anything has it doesn't
have any NAND or emmc and the only change is that the am335x_boneblack
uses emmc to save the environment instead of trying (and failing) to
save to NAND.

There's two ways to go about improving the out of box experience.  One
of which would be to switch "beaglebone" to am335x_boneblack config
which will switch env saving to eMMC and leave BBW just as unable to
have persisent env (outside of uEnv.txt) as today.  Another would be to
bring in http://patchwork.ozlabs.org/patch/375824/ (which will be merged
to mainline) and
https://git.ti.com/ti-u-boot/ti-u-boot/commit/b8fce957880e6c4194614260f70be4e7f2c9f469
(which will not, we'll instead get env location migrated to Kconfig
choices and leave it to the user to pick where they want things to be)
which puts everything in a binary file on the FAT partition of the SD
card which is also pretty frequently available.

Either one is honestly a fine improvement.

Do you have a branch with both patches applied? Or maybe it is simpler
to wait for the first one to hit mainline and upgrade the u-boot recipe
at that time.

I'm a bit concerned that the second patch will actually change the
behaviour of the am335x_evm config, switching from reading the env in
nand to that file in the first FAT partition. Do you want to change
that?

In terms of general out of box experience, yes, I wanted to change
everyone over.  Of all the boards am335x_evm supports (GP EVM, IDK EVM,
EVM SK, BBW, BBB) only GP EVM and maybe IDK EVM (not seen one myself)
have NAND normally.  All of them have SD card support 'tho.
