[U-Boot] [PATCH] ARM: socfpga: Convert to DM serial

Pull the serial port configuration from DT and use DM serial instead of having the serial configuration in two places, DT and board config.

Unfortunately I saw this just now, but it seems this breaks GEN5 SPL? At least git-bisect told me that 73172753f4f3351ed1c9d2f6586fc599ce4e728c is the first bad commit.
I tested socfpga_socrates_defconfig on my socrates board.
Any idea what's wrong there?
Regards, Simon

Nope, this should work fine. Can you investigate ?

Ok, so after adding "u-boot,dm-pre-reloc" to uart0 in socfpga_cyclone5_socrates.dts, U-Boot works (combined with an old SPL). SPL still does not work. Any idea? How does SPL get the uart?
Thanks for any pointers.

Unfortunately I saw this just now, but it seems this breaks GEN5 SPL? At least git-bisect told me that 73172753f4f3351ed1c9d2f6586fc599ce4e728c is the first bad commit.
I tested socfpga_socrates_defconfig on my socrates board.
Any idea what's wrong there?
Nope, this should work fine. Can you investigate ?
Ok, so after adding "u-boot,dm-pre-reloc" to uart0 in socfpga_cyclone5_socrates.dts, U-Boot works (combined with an old SPL).
Good!
SPL still does not work. Any idea? How does SPL get the uart?
Thanks for any pointers.
Dig around the NS16550 driver .

Not much I believe, I can't think of anything right now.

Yes. The pinmux docs are probably not public, it has to do with the iocsr ring programming and that's super-secret for whatever reason. What Altera did on Arria10 is pure trash, they encode registers in DT and are done with it. If you can design something saner, that'd be so nice.
I am working on a clock driver for Arria10 now, I might do Gen5 too afterward, since the clock block is similar. The clock DT bindings on the other hand are complete insanity, words fail me. The clock stuff in U-Boot on SoCFPGA right now is a complete disaster too, the way stuff gets added to mach-socfpga is really irritating.

DTOs maybe ?

As I'm not familiar with pinmux DTS, that might be hard for me, but I might try to get it done somehow (or by someone... :)
Could you give me a hint of a platform to take as a good example?

That would be cool. You can count on me testing on cyclone5 as much as I can (as much as I have the hardware, that is).
The clock DT bindings on the other hand are complete insanity, words fail me. The clock stuff in U-Boot on SoCFPGA right now is a complete disaster too, the way stuff gets added to mach-socfpga is really irritating.
But you would still use the existing bindings? How does this stuff get added to U-Boot, by first being added to Linux and the DTS being copied here?
I'm looking for a way to control pins from a fit image that includes kernel, dts and fpga because the pins may change depending on the fpga config...

Yeah, I thought of that too. The problem I see is that we would need pinmux and clock support for DTS in Linux but we're kind of stuck to 4.9.y for now due to using an RT configuration.

Maybe iMX series ?

Pretty much, except on A10 there are the generated handoff files at play too. Basically Altera really screwed it up there, it contains redundant nodes which are both in the base DT and handoff files, but each contain different set of DT properties and have different names, although they represent the same thing. Sigh ...

Well, implement those drivers ?

OK, so my DS-5 debugger shows me it's not the driver that fails but "malloc_simple()" returns 0x0 when being called from uclass_get_device_by_seq(). Which is strange because gd->malloc_base is 0xffffe000.
Also, gd->fdt_blob is not initialized at the time serial_init() is called from SPL. Should it be? Because that way, we don't seem to have dts control over which uart is used as console?

73172753f4f3351ed1c9d2f6586fc599ce4e728c
is the first bad commit.
I tested socfpga_socrates_defconfig on my socrates board.
Any idea what's wrong there?
Nope, this should work fine. Can you investigate ?
Ok, so after adding "u-boot,dm-pre-reloc" to uart0 in socfpga_cyclone5_socrates.dts, U-Boot works (combined with an old SPL).
Good!
SPL still does not work. Any idea? How does SPL get the uart?
Thanks for any pointers.
Dig around the NS16550 driver .
OK, so my DS-5 debugger shows me it's not the driver that fails but "malloc_simple()" returns 0x0 when being called from uclass_get_device_by_seq(). Which is strange because gd->malloc_base is 0xffffe000.
malloc() returns NULL because it ran out of space ?
No, the malloc limit is not even set in gd. It just somehow fails to add malloc_base. I don't get why, as it should do so given the disassembly.
The next step is then zeroing the memory from calloc() and it doesn't return from there.
I guess next I could check if malloc_simple is called at all without serial DM. That would at least explain how this error is connected to your commit...
Also, gd->fdt_blob is not initialized at the time serial_init() is
called from SPL. Should it be? Because that way, we don't seem to have dts control over which uart is used as console?
Can someone shed some light on this? Should the device tree be available when allocating the SPL console? Because if not, it would just use the first driver available, or am I wrong?

I know. That's why I just tested with a smaller config where I disable spi and spi-flash drivers. The SPL binary is now only 40kbyte but the error remains the same.
I wonder if the cause might be that now malloc_simple() is called earlier than before?

Maybe it's not, I recall that the SPL sometimes failed when it grew too large and noone explained in a satisfactory way why. Maybe the commit just triggers this.
I know. That's why I just tested with a smaller config where I disable spi and spi-flash drivers. The SPL binary is now only 40kbyte but the error remains the same.
I wonder if the cause might be that now malloc_simple() is called earlier than before?
And this was the right direction: malloc_simple just did not work at that time in the boot. But after fixing this (patches pending) other things (e.g. in dm core) did not work.
The solution was to call 'spl_early_init()' from socfpga's 'boart_init_f()', which not only correctly inits the heap but also inits the dm code.
Now the SPL is working for me, too! :-)
I'll have to prepare patches on top of the current git master though: for now, I have only tested changes on this patch.
I really don't know how this could have worked for other socfpga boards, but I saw the SPL split coming later after this patch, and I must say I don't think it's such a good idea. I'd prefer if all the socfpga platforms could stay with one SPL. That would greatly reduce that chance of old platforms getting broken like this.
Thanks, Simon

I agree, then again the Arria10 has quite different needs in SPL and than the Gen5 . Obviously, if the differences could be somehow pushed into drivers, that'd be nice.
