This series adds support for the Toradex Apalis TK1 and introduces a new
option to disable the external clock loopback on SDMMC3.
The whole series is also available here:
http://git.toradex.com/cgit/u-boot-toradex.git/log/?h=for-next
Changes in v4:
- Re-based.
- Drop patches 2 and 3:
mmc: tegra: move CONFIG_TEGRA_MMC from headers to defconfigs
mmc: tegra: introduce CONFIG_TEGRA_MMC to Kconfig
in favor of commit 1d2c0506d31a9997e5ffc22e90942902f673b107
mmc: move more driver config options to Kconfig
from Masahiro.
- Meld patch 6
apalis-tk1: clean-up defconfig
into first one.
- Add distro boot fallback.
- Enable FIT and device tree overlay support.
- Explicitly drop EFI loader support.
- Re-based.
Changes in v3:
- Changes involved now dropped patches.
Changes in v2:
- Added Simon's reviewed-by.
- Added TODO(email) as suggested by Simon so it is clear this is
temporary and will be moved to device tree controlled approach once
proper kernel integration made it mainline.

This patch adds board support for the Toradex Apalis TK1 a computer on
module which can be used on different carrier boards.
The module consists of a Tegra TK1 SoC, a PMIC solution, 2 GB of DDR3L
RAM, a bunch of level shifters, an eMMC, a TMP451 temperature sensor
chip, an I210 gigabit Ethernet controller and a SGTL5000 audio codec.
Furthermore, there is a Kinetis MK20DN512 companion micro controller for
analogue, CAN and resistive touch functionality.
For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.
The following functionality is working so far:
- eMMC boot, environment storage and Toradex factory config block
- Gigabit Ethernet
- MMC/SD cards (both MMC1 as well as SD1 slot)
- USB client/host (dual role OTG port as client e.g. for DFU/UMS or host,
other two ports as host)

Introduce CONFIG_TEGRA124_MMC_DISABLE_EXT_LOOPBACK to disable the external clock
loopback and use the internal one on SDMMC3 as per the SDMMC_VENDOR_MISC_CNTRL_0
register's SDMMC_SPARE1 bits being set to 0xfffd according to the TRM.

Changes in v4:
- Re-based.
Changes in v3: None
Changes in v2:
- Added Simon's reviewed-by.
- Added TODO(email) as suggested by Simon so it is clear this is
temporary and will be moved to device tree controlled approach once
proper kernel integration made it mainline.

Yes, a waste of 20K which on some of our modules is rather crucial. I
personally think force enabling EFI for everything was not too smart an
idea but whatever.

Well, it's enabled by default for a good reason: Compatibility. I want
to move to a world where people can just take a random distribution and
expect it to work, rather than waste weeks over weeks on fiddling around
with random BSPs that nobody really wants only to realize 2 years down
the road that their security footprint is en par with a swiss cheese.
It's also the preferred option to boot BSD for example.
So how bad are the 20k for you? In fact, I'm surprised it's 20k at all -
it used to be 10k. The overhead of DM should be much higher and I doubt
you want to disable that ;). Usually a full U-Boot build is ~500k, so
even at 20k we're talking about 4% - less than a compiler update usually
gets you.
If size really is such a big concern, moving to THUMB code is going to
buy you much more in storage savings than dropping (quite useful) UEFI
support.
If however there are real technical issues with it, I'm happy to hear
them and fix them as far as possible.

While I do agree about compatibility I don't quite see what this has to
do with EFI. I personally don't believe the BIOS/EFI disaster of the
x86 world is worth copying to ARM, sorry. Other distributions like
Fedora e.g. achieve the same with distro boot isn't it? After all isn't
the device tree the agreed upon hardware description in the ARM world?

Hey, nothing against Swiss cheese! And BTW the term Swiss cheese is
about as nonsense as the term Linux. There is really a huge collection
of different Swiss cheeses... Sorry, I just do get upset at times if
certain countries gastronomy people do ask whether I want my sandwich
with Swiss cheese wondering what they mean by that. But I guess those
chaps now do have their very own issues (;-p).

The technical issue is that I still don't quite see why U-Boot needs
EFI. I stopped using SuSE more than 15 years ago and never regretted
it, no pun intended.
But if it is really agreed upon mandatory to enable it I am happy to do
so as I would love to finally get that thing in after an almost 4
months endeavour.

Fedora uses extlinux for 32bit ARM and UEFI for 64bit ARM. The main
reason they're using extlinux is that at the point in time when they
standardized on it as their preferred booting method, the UEFI
implementation didn't exist yet.
> the device tree the agreed upon hardware description in the ARM world?
Yes, device tree is very much agree upon as hardware description! And
with UEFI nothing changes in that regard. We still use device tree by
default and unless you're really into shooting yourself into your own
feet I don't see why you'd want to do it any differently.
This is not an ACPI vs DT discussion. It's really just about the
question which entity controls selection and handover into the kernel.
With UEFI it's much easier to implement snapshot booting for example,
because you can move all of that logic into a platform agnostic piece of
code. It's the only supported way to have KASLR work on arm64. It allows
for boot selection logic (A/B fallback for example) in something outside
of a boot script or your boot loader sources, so that code stays reusable.
Take a look at my video at ELC for some rationale behind it:

For 32bit ARM it doesn't really "need" it. If you feel terribly strongly
about it, I don't have hard feelings with leaving it out. But if it's
really just a matter of taste rather than technical merit, I'd rather
prefer to have the option available for users. The same reason you
usually want to have distro boot support enabled and not just a
hardcoded bootcmd line.

I'm not nacking this patch set, even with EFI_LOADER disabled. But I
think that if there's no good reason to disable the feature, we should
leave it enabled.
And if you really are size constrained with today's configuration,
please enable thumb2, otherwise you will get bitten on random compiler
updates down the road.
Thanks,
Alex

Another area which probably will never generically work across all
hardware just because there are simply too many hardware variants out
there in the 32-bit ARM world.

Yes, I have seen that one before and we were shaking our heads. But
maybe it really is the way to go just like systemd is now ruling the
world (;-p).

OK, I will send a V5 which does not explicitly disable it.

Unfortunately the platforms I have that are space constrained do not
support any such but again those probably won't ever run any regular
distro neither.

It's your board, I don't see why you can't disable it.

We certainly should not mandate EFI support in U-Boot :-( I think it's
a nice idea if you have to use EFI/grub on your system though. A great
way to get past the legacy problem.
Anyway, the video looks interesting - are the slides available
somewhere? I'd really like to see how this is presented.

Simon

I don't think anyone mandates EFI support. I merely asked for reasoning
why it was explicitly disabled - with a preference not to have it
disabled, but that's by no means a mandate :).

The slides should be on the ELC web site, yes:
http://events.linuxfoundation.org/sites/events/files/slides/Marrying%20U-Boot%2C%20UEFI%20and%20grub.pdf
They're presented using keynote on a Mac. I haven't found anything
remotely as comfortable for creating presentations anywhere else :).
