Enable ATAG_DTB_COMPAT support for passing commandline from bootloader.
Enable initrd support.
Signed-off-by: Kevin Hilman <khilman@linaro.org>
---
With this, I can finally integrate the kzm9d into the board farm because I use
initrafms for the primary rootfs, and set the command-line from u-boot.

Thanks, I will queue this up for v3.18 and push it to next
once v3.17-rc1 has been released.

Hi Kevin,
I have decided to drop this patch for now as it appears to
cause my kzm9d (of all things) not to boot. And per a follow-up email
from you it no longer appears to be required in your environment.
I'm more than happy to revisit this if it turns out to be useful again.

"ARM: shmobile: defconfig: enable initrd and atag dtb compat" enables
CONFIG_ARM_ATAG_DTB_COMPAT, however, empirically
ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND is also required for my kzm9d board to
boot.

Actviate HDMI output of the RCar DU (and LVDS while we are here).
Enable the HDMI encoder chip found on Lager/Koelsch boards.
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>
---
This is the final bit needed to get HDMI output with an shmobile_defconfig
built kernel. The other bits were renesas-devel-20151008-v4.3-rc4 plus some I2C
patches, which are already in my for-next or soon in my for-current branches.
The complete branch can be found here:
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/rcar-hdmi-output
Tested with a Lager board and using both I2C/IIC. Based on my testings in
Dublin with a Koelsch board, I'd be very surprised if it fails with Koelsch.
Laurent may prove me wrong ;)

Thanks, I have queued this up for v4.4.
Is a similar change appropriate for multi_v7_defconfig?

I've tried to reproduce the problem tonight and couldn't, even without your
recent i2c-rcar patches :-/ I'll keep running tests on Koelsch with that
configuration and make sure to report any issue I can find.

Thanks for testing!
The good news of your message is that HDMI works on Koelsch, too :)

The Koelsch that failed has a much newer U-Boot (b653737dfca2), which
only enables the MSTP clocks that are really needed, while you and I have
much older versions (I have b6af5fcc8dfc).

With the new CPG-MSSR driver it should be possible to disable unused
MSTP clocks in the kernel during boot without too much trouble, right?
Of course it is not something that is needed right away, but DT
architecture wise it seems possible to squeeze that in without having
to update the DT binding.

Unused clocks are already disabled by the clock framework, but that
happens at late_initcall() time, i.e. after i2c probing.
Or do you mean disabling them upfront?
There are some clocks that must not be disabled. Some of them are not
documented.

Disabling them upfront with sparse documentation seems fun, but also a
bit like asking for trouble. =)
So disabling clocks upfront may be a troublesome but good way to
trigger incorrect dependencies, and unless I'm mistaken it should give
the same behaviour as the updated u-boot version, right?

I have hackish code that does it for all boards I have, and use it actively.

More or less (U-Boot still keeps a few enabled for its own use, e.g. Ethernet).

What Laurent saw was a 1 byte shift in the transferreed EDID data. So,
most likely not a MSTP clock related problem ;)

Seems like a good feature to me!

So it fails to cleanup after itself then... But by disabling clocks
upfront I guess you can be even more aggressive.
Anyway, it would be nice to see that feature upstream at some point.
Let me know if there is anything I can do to help!!

It failed on my Koelsch before, and I have never updated U-Boot on it.

AFAIK, in some recent versions of Gen2 BSP, all the devices (including
all devices enabled by u-boot for its processing, like Ethernet, TMU,
serial) will be turned off right before jumping to kernel start address.

Would it make sense to keep the serial port enabled in order to support early
printk ?

I don't think early printk is supported in Gen2 BSP, which is base on
LTSI 3.10.
Geert has introduced early printk support for Gen2 in Nov 2014.
Maybe, we need to consider this point for Gen3.

INTC-RT, MFIS, INTC-SYS, IRQC, and SCIF0 are left enabled, according
to the U-Boot sources.

Yes, you are right. Above devices were left enabled.
Especially, some interrupt controller devices need to keep ON to ensure
system operation
while transferring to kernel boot.

Enable timestamps for kernel log output to improve debugging.
You can always use "dmesg -t" to strip the timestamps.
Don't specify CONFIG_LOG_BUF_SHIFT\x16 while we're at it. There's a
reason the default in Kconfig is higher ;-)
