[U-Boot] [PATCH 1/8] Tegra124: Add arch-tegra124 include/header files
No real HW change on T124 for 90% of the toys, so just include a common T1x4 header file (based on T114 headers), and if a new register/bit is needed, add it at the end. Some headers (clk_rst, clock-tables, pinmux, etc.) had too many changes in structs, devices, etc. added/removed, so they are added as complete new files for T124, and can be diffed against T114 headers to see what's changed (again, not a lot).
In a future (RSN) patch I'll point the T114 headers at the new common tegra1x4-xxx files, too.

Shouldn't this pass along the partid as well? Otherwise, how does the is_partition_powered() function know what to check for. Perhaps I'm confused by the API here. Why do we even pass around status in the first place? The partition ID should be enough, shouldn't it?

Ah, I see now. I'd find something like the following more intuitive:
power_partition_set(CRAIL, true);
But looking deeper I see that we already have the same API for earlier SoC generations, so I suppose we might as well stick with it.
The current API always has the risk of someone doing something like:
power_partition(CONC, CRAILID);

I don't think any of the comments above add value, so they can just as well be dropped. The code is self-explanatory.

Given that the only exception is Tegra20, wouldn't it be better as:

and then swap the Tegra20/not-Tegra20 branches of the if statement?

(I'm working on finalizing this patch for submission now)
I think it's fine for the core driver to know about the different SoCs. A simple ifdef like this is quite manageable. If the code starts to get unmanageable, or does a lot of things that aren't common across chips, we can always split it out into the SoC-specific files.

The build of these files isn't enabled until the last patch anyway, so it's all perfectly bisectable. I'm not included to do anything to fix this unless you feel strongly..
I'll fix up all the other issues you mentioned.

I would have expected a lot more of that file to be common with tegra114/cpu.c, considering the tiny size of the kernel patches for SMP support, CPU hotplug support, etc.
These files are for code that runs on the CPU (A15) on T124 boards. At this time, there is no A15-specific code here. The warmboot/LP0 files aren't included as that code hasn't been ported yet.

Why change the indentation level here? The if (xxx) return could have been enhanced to check for either chip without changing the indentation level of the rest of the function.
Also, we shouldn't be checking for the SoC, but rather for the CPU core type. On A9 we want to return. On A15, we want to continue. If we had written the code to check the correct thing before, we wouldn't have to touch this function at all when porting to Tegra124.
Basic Tegra124 build support added - no specific board is targeted.

The content of this patch seems entirely unrelated to the commit description.
BTW, if I apply each one of these patches in turn, rather than all of them at once, can the entire code-base build correctly for all SoCs, or will I get build errors? I suppose that the boards.cfg is added near the end of the series, so perhaps there's no issue here.
These are fairly complete, and near-clones of T114 Venice, with an additional I2C port, and MMC address changes for T124.

I strongly doubt that the Tegra124 CAR is backwards-compatible with the Tegra114 CAR. I think that should be:
compatible = "nvidia,tegra124-car";
Have you validated all the compatible values in this file to make sure they're accurate? I'd tend towards leaving out DT nodes that aren't useful yet to reduce the need to verify this, unless you intend to add all the drivers very quickly.
reg = <0x60006000 0x1000>;
There's been a DT rule change/clarification. All DT nodes that contain a reg property must contain a unit address in their node name. DT nodes without a reg property must not contain a unit address in their node name. As such, this should be "clock@60006000" not "clock". I'd like to see this rule applied to DTs for all new SoCs going forward, even if we haven't yet thought through fixing up all the existing DTs to comply with the rule.

It'd be nice to finally import include/dt-bindings from the kernel so we could use named constants instead of magic numbers for the "0x04" here...

These don't conform to the latest USB bindings, which have split EHCI controller and PHY nodes.

These are the board files for Venice2 (t124), plus the AS3722 PMIC files. PMIC init will be moved to pmic_common_init later.
This builds/boots on Venice2, SPI/MMC/USB/I2C all work. Audio and display and WB/LP0 are not supported yet.

These are the board files for Venice2 (t124), plus the AS3722 PMIC files. PMIC init will be moved to pmic_common_init later.
This builds/boots on Venice2, SPI/MMC/USB/I2C all work. Audio and display and WB/LP0 are not supported yet.

Wouldn't it be better to only include the active code? We can always just make a patch to move to different code later if we want.

That doesn't seem sorted. I would have expected tegra114 before tegra124? Same if it's sorted by board name.

A blank line is typical after the include guard.
+#define CONFIG_TEGRA124 /* in a NVidia Tegra124 core */
NVIDIA not NVidia.
+#define CONFIG_SPL_LDSCRIPT "$(CPUDIR)/tegra124/u-boot-spl.lds"
I don't think that's used upstream. Perhaps diff these files against the Tegra114 versions and check for unexpected differences?

We should either always do that or never; boards shouldn't make the decision. Rather, the core Tegra code should make the decision based on the SoC ID.
Also, CONFIG_TEGRA_USE_EMC_DRAM_SIZE doesn't exist upstream.

Dalmore says:
#define CONFIG_ENV_OFFSET (-CONFIG_ENV_SIZE)
... which seems a bit more self-managing.

In a future (RSN) patch I'll point the T114 headers at the new common tegra1x4-xxx files, too.

As a general note: you should strip these Change-Id tags when posting patches upstream. It's completely useless unless you provide a URL and access to the gerrit instance that carries the change.

For the reasons I mentioned earlier, I'd like to avoid "tegra1x4" in these filenames too.
