To: u-boot
Common Tegra files are in arch-tegra, shared between T20 and T30.
Tegra30-specific headers are in arch-tegra30. Note that some of
these will be filled in as more T30 support is added (drivers,
WB/LP0 support, etc.). A couple of Tegra20 files were changed
to support common headers in arch-tegra, also.
Signed-off-by: Tom Warren <twarren@nvidia.com>
---
V2:
* Created common header files in arch-tegra.
* Reworked pmux func name enums, RSVDx values to end of list.
* Added spl.h for T30, removed emc.h.

Can you remind me why TEGRA_SOC_T30_408MHZ exists; isn't it a SW thing
whereas this enum is meant to be identifying the HW?

funcmux isn't going to be remotely useful for Tegra30. There are
something like 460 possible ways of muxing out (IIRC) just a 4-pin UART
A on Tegra30. That's why when I was defining the proposed ODMDATA2
representation of UART pinmux for the Tegra30 BCT, I didn't have a
single enum covering the entire UART configuration, but rather a 4-bit
field per signal (RXD, TXD, RTS, CTS) that indicated which of the
possible pins to route it to.
Still, I guess having the initial port use funcmux is fine since we only
need to support 1 option for now. We'll hopefully just convert it to use
the BCT ODMDATA2 format rather quickly.
A similar comment will probably apply to any other peripheral on Tegra30.

It exists in our internal repo, and I don't want to remove it until
I've brought our upstream version fully up-to-speed @ 408MHz. This
initial patchset runs T30 PLLP @ 216MHz, with an option to upgrade to
408MHz at runtime. Once this baseline T30 support is in, I'll look
into making PLLP 408MHz from the get-go.

Yeah, I wanted to get this in, then let your ODMDATA2 change migrate
in, and then convert over to using that for UART init for T30 too.

This provides SPL support for T30 boards - AVP early init, plus
CPU (A9) init/jump to main U-Boot.
Some changes were made to Tegra20 cpu.c to move common routines
into tegra-common/cpu.c and reduce code duplication.

Just a minor note here; this patch both moves a bunch of code from cpu.c
to the new cpu.c, and adds Tegra30 support. It would have been a little
easier to review if the code move were a separate patch (with git
format-patch -C) so that it was obvious what code in the new cpu.c was
changes due to Tegra30 and what was just copied.

Perhaps. But I didn't want to delay the T30 patches any longer while
waiting for a 'commonize cpu.c' patchset for T20 to trickle through.
I had also tried creating this particular patch with 'git-format -M
-C', and it created confusing 'copy foo->bar' lines for some of the
other files that were potentially more confusing to the reviewer than
the larger cpu.c diff. So I went with a the broader patch.

These files are for code that runs on the CPU (A9) on T30 boards.
At this time, it's only the RCM (Recovery Mode) cmd file, which
is in tegra-common. As T30-specific run-time code is added, it'll
go here.

These files are used by both SPL and main U-Boot.
Also made minor changes to shared Tegra code to support
T30 differences.

Just for completeness, I'm going to mention again that I think this
should just return TEGRA_SOC_T30 all the time. Sorry if that's
belaboring the point!
I just noticed your recent email saying you got 408MHz working, so I
guess my comment is moot anyway:-)

This is fine, but the following wouldn't require editing again for
future chips:
puts(CONFIG_SYS_SOC);
puts("\n");
(although it ends up being all lower-case; perhaps there's some other
variable that is upper-case?)

Yep. TEGRA_SOC_T30_408MHZ is gone; TEGRA_SOC_T30 is returned for Tegra30.

How about this:
#include <common.h>
#include <linux/ctype.h>
#ifdef CONFIG_DISPLAY_CPUINFO
void upstring(char *s)
{
while(*s) {
*s = toupper(*s);
s++;
}
}
/* Print CPU information */
int print_cpuinfo(void)
{
upstring(CONFIG_SYS_SOC);
puts(CONFIG_SYS_SOC);
puts("\n");
return 0;
)
#endif
What do you think?

CONFIG_SYS_SOC is presumably stored in a read-only segment, so that
might not even work, although I dare say memory protection isn't enabled
to prevent this. That would also end up modifying the string itself,
which is probably used elsewhere, where such modification might not be
desirable.
If you called upstring() on a copy of the string e.g. on the stack, that
seems reasonable.

It does work - I wouldn't present code w/o testing it :)
But the side-effect of modifying CONFIG_SYS_SOC is probably a bad thing.

I'll copy the string first. I was trying to minimize the amount of
extra code added.

These are stripped down for bringup, They'll be filled out later
to match-up with the kernel DT contents, and/or as devices are

We don't really need a model property here, but it's not a big deal.

/memreserve/ isn't correct for U-Boot; no memory should be reserved.

That last number should be 0x40000000; it's a size not an end-of-region
value.
Note that once things get more advanced, we'll need to split this up
into tegra30-cardhu.dtsi, tegra30-cardhu-a02.dts,
tegra30-cardhu-a04.dts, but we can do that later.

But don't we want to use the same fdt for U-Boot as the kernel?

Hmmm. The tegra20.dtsi file doesn't have one...

The only reason for a memreserve are:
a) To reserve the current display frame-buffer. This is a run-time thing
that U-Boot should add to the DTB itself, not pre-populated in the DT.
b) To reserve memory for some kind of co-processor. We shouldn't be
using memreserve for this any more, but rather allocating the memory
dynamically in the kernel.
So irrespective of the answer to your question we should still remove this.
Re: your question: Perhaps, but we're so far away from that right now,
it almost doesn't seem worth caring yet. Also, while we should certainly
use the same bindings, I'm not sure we should use the same actual .dtb
file bitstream, since the .dtb passed to the kernel should be loaded
from the filesystem/... where the kernel zImage was, not embedded into
the bootloader.

No problem, then it won't display a model.

I don't really mind, but I hold fond hopes of using the same source
for each at some point. Not an issue for now.

Actually, every other build (T20) has the model declared in the .dts
file. Stephen is correct that T30 has it in the .dtsi file, too (not
sure why - another artifact of our internal repo), so removing it will
bring it in line with all the other Tegra builds, and (I assume) will
still display a model name.

Note that the only Tegra20 build that has a memreserve declared
(besides T30) is Seaboard.
I'll remove it, as well as the extra model = line in the .dtsi.

board is targeted.

Why is that required? If it is, why doesn't Tegra20 require it too?

Tegra30 does a table-driven pinmux init. This has the advantage of
ensuring all pinmuxes are in a non-conflicting state (some of the POR
defaults can cause conflicts).
Drivers are free to reconfig during device discovery if necessary (it
usually isn't), or while parsing the DT.

This build is stripped down. It boots to the command prompt.
GPIO is the only peripheral supported. Others TBD.
include/configs/tegra-common.h now holds common config options
for Tegra SoCs.
Signed-off-by: Tom Warren <twarren@nvidia.com>

V2:
* Move pinmux_init to cardhu.c, move pinmux-config header here, too.
* tegra-common.h holds CONFIG options/defines commmon to all Tegra SoCs.

Oh, I see. Is any of the pinmux configuration actually needed for just
the UART to work? I suppose there's not much harm just setting up the
whole configuration from the start rather than adding it piece-meal.

I'm pretty sure that define will never be enabled; it was some temporary
test thing that should be removed from our downstream kernel, which is
where I assume you got this table from.

Is that correct for Tegra30?

I thought PLL_P ran at 408MHz on Tegra30? The kernel certainly sets it
up that way.
In this patch, you also should move MEM_LAYOUT_ENV_SETTINGS from
tegra-common-post.h into tegraNN-common.h, or something like that.

Yep, see previous reply for an explanation of why it's done in one shot.

No, this came from one of our internal T30 U-Boot branches. Not sure
where the OD (original dev) got it from.
I'll remove the REALTEK parts.

It was originally in tegra20-common.h, and was moved into
tegra-common.h in a batch with other thought-to-be-non-HW-specific
config defines.
Looking at the code, though, I don't see it used anywhere. It can be
removed, either in V3 of this patchset or in a clean-up round of
patches later once T30 is in.

See my previous reply. In the internal U-Boot repo I ported from, PLLP
was initially set to 216MHz, then sped up to 408MHz. When this first
round of patches is in, I can address going to 408MHz first thing.

I can do that, or we can wait until those settings are going to be
used, i.e. once I've added peripheral support so a kernel can be found
and loaded and executed.

Is running the PLL_P at 408MHz something which requires a lot of work?
If not, please do this and fold it into this patchset. It doesn't look
too nice adding things to upstream which have to be changed/removed
immediately after going in.
Considering that Tegra 30 support is still not really in a usable state
after this patchset and the time left until things have to get ready for
the next merge window, I suppose you could do it the right way from the
start.

Lucas

Naively I'd have to agree here; it seems that programming the PLL for
the correct rate would probably "just work" right from the outset? After
all, if the code runs OK with the higher rate enabled a little later in
boot, I see no reason it shouldn't run OK with that exact same rate the
whole way through.

Thanks. As I remember it, it was a user-config option for early T30
boards to run at 216MHz or 408MHz. The 408MHz PLLP change generated a
lot of email traffic on what the best output clocks (pllp_out1 thru 4)
would be for the various periphs, subclocks, etc.
When I did the original bringup for upstream U-Boot on my (older)
Cardhu, I wanted to start at 216MHz first, then step up to 408MHz when
I was at a stable point. Much like when I rebuilt my Mustang - I took
it out around the block first, to be sure everything was working OK
before I took it on the highway ;)
I'm running OK at 408MHz on my Cardhu T33. I'll resubmit V3 of the
patchset in the next day or so.
Thanks,
Tom

Isn't it just cut/pasting those 5 lines (well, and the comment before
them I guess) and s/0x0/0x8/ in all the lines. It seems pretty easy to
get the right values in from the start.
Without this, it's a PITA to test bootm with this U-Boot (you can
download a kernel over serial with loady for example; something I tested
with earlier revisions of this series).

I'll move the MEM_LAYOUT_ENV_SETTINGS (and update the addresses) since
I'm doing a V3.
Also, WRT the 408MHz tweak, I got it working w/relatively little pain.
That'll also be the de facto PLLP speed for T30 in V3 of the patchset.
Thanks,
Tom
