[U-Boot] [NEXT PATCH v1 0/7] In this patchset, a new i.MX35 board is added implementing

[Stefano Babic]

the internal boot mode and using the general SPL Framework.

For this reason, this patchset depends on:

Tom Rini's SPL generic framework:
	http://lists.denx.de/pipermail/u-boot/2012-August/132813.html

To fix that relocation should not happen in SPL, the following patch
is also required:

	http://patchwork.ozlabs.org/patch/181166/

The woodburn board boots from SD Card. However, the presented way
introducing SPL is general, and can applied to other devices.



Stefano Babic (7):
  ARM: Fix start.S when used with SPL in arm1136
  NAND: added NAND type to nand_ids
  MX35: add LOW_LEVEL_SRAM_STACK to use SPL_FRAMEWORK
  MX35: Add soc_boot_mode and soc_boot_device to MX35
  SPL: Added MLO for mx35 SOC to SPL Makefile
  ARM: Add MLO target to arm1136
  MX35: add support for woodburn board

[U-Boot] [NEXT PATCH v1 1/7] ARM: Fix start.S when used with SPL in arm1136

[Stefano Babic]

This patch modifies start.S for the arm1136 to make it
conform to start.S  in armv7 architecture, to make it
usable if the SPL framework is used.

Why does this NAND chip need things specified that are zeroes for other

At least on this board with MX35, the chip cannot be recognized.
Manufacturer ID and device ID are read flawlessly, but then u-boot fails
to get the correct geometry. Setting explicitely the values, I can then
read / write into the NAND without any problem. It can be more a problem
related to the specific MXC NAND driver (mxc_nand.c).

Regards,
Stefano

It seems to me that the values returned by this flash cannot be
interpreted in nand_get_flash_type().

The values returned from a READ-ID command with address 0x00 are:

	0x2C 0x48 0x04 0x4A 0xA5,

I can really get these values from the flash, so the MXC controller gets
the correct data.

However, the code in nand_base.c (lines from 2718, so not-Samsung case)
parses the answer setting the NAND as a 16-bit device, but this is
really a 8bit device. I do not know the meaning of the answer, it is not
described in the datasheet.

Cheers,
Stefano

Does the datasheet say anything about what the ID data is supposed to
look like and how to interpret it?  I tried to download it and Micron
shoved an NDA in my face.

What kind of chip is this?  Is the datasheet publicly available?

These threads seem relevant:
http://patchwork.ozlabs.org/patch/60042/
http://old.nabble.com/-U-Boot--Add-new-NAND-flash-td29858370.html

Does the chip support ONFI?

It is the same case,  as I can see, with the same chip.

The chip supports ONFI, but it seems the i.MX driver does not. Quite as
described in http://patchwork.ozlabs.org/patch/60042/. READ-ID is always
sent with address 0, I do not know if we can convince the driver to send
the address.

Stefano

How did Linux end up resolving this?  I think it'd be better to have the
Micron decoding logic from that patch, than to introduce a special
addition to the ID table for this one chip, which might not be correct
for all chips with that ID byte.

Or, we could treat it as information to be supplied by platform code (or
the device tree).

I could take a closer look. The issue is not solved on linux, too. In
fact, the MXC driver in current kernel supports ONFI, but it should work
for newer version of the controller - I think with MX5.

On MX35, the NFC controller is V1.1, exactly as on MX25, and I have the
same issue reported by Matthias that you pointed out in the past
threads: ONFI command does not work.

Agree. I am trying to contact Micron to get some information about it. I
have tried to decode the bytes on basis of other Micron's NAND, but then
bit 6 in byte 4 says that the NAND is a 16 bit device, and that is
wrong. Exactly the same wrong value that Matthias found some times ago.

to add ONFI support to i.MX's driver, you can check this patch (in
barebox, a similar patch for Linux is cooking, actually tested on
i.MX53 and i.MX25) :

thisseems not clean and seems caused by the fact that the define
RCSR_MEM_CTL_SD should be 3 and not 2 so in your tests the function
spl_boot_device was not detecting the right boot mode. Also IMHO this
define should be named RCSR_MEM_CTL_EXPANSION as in the app note AN3996
at end of page 3 (there is a typo in the reference manual which seems
to be a copy'n paste from i.MX25 as it doesn't take in acount the ATA
HDD case) :

Is that really the name you want?  MLO comes from some part or another
(I've read it, just can't recall off-hand) of the IT ROM docs saying it
will read a file named MLO.  Is mx35 in the same boat?  Or just looking
for a common name?  Thanks!

Right. It makes no sense that the binary for Freescale's SOCs has a
name, for TI another one, for...we can generates less confusion if we
uses the same name.

Agreed.  I guess what I'm asking is, in the TI case the ROM reads FAT
and must find 'MLO'.  Does mx35 do the same or is the post-build step
"dd if=MLO of=/dev/... ..." and the filename doesn't matter?  I'm fine
with the change now, just looking for the full details.  Thanks!

No. And not only the MX35, but also the MX5/MX6.

Exactly. The ROM does not understand a filesystem, and the SPL must be
stored at a fixed address in the SD card. The filename does not matter,
and the SPL is not seen as file, but as a raw image.

As for Freescale the filename does not matter while for TI does, we can
use for both MLO ;-)

Then in that case I would precisely *not* use the same filename, in
order to make it clear that Freescale SPL cannot be used in the same
way as the TI SPL. Naming it MLO will certainly confuse users having
previous experience with TI stuff: it will lead them to believe that
creating a FAT filesystem and putting the MLO file in it will be the
necessary steps to get this SPL loaded by the ROM code.

Best regards,

Thomas

Of couse, setting a common name is not a reason enough for the users to
not read the manual ;-). The way TI and Freescale have chosen to boot
their SOCs are and remain quite differently.

The reason to have a common name is to avoid to document for each SOC
which is the binary result. Maybe a more neutral name as "SPL" instead
of "MLO" ? This is the first attempt to set SPL for a not-TI SOC, but
hopefully other SOCs will follow, and it is better to set already some
simple rules,

In any case, the resulting binary is a different thing as how to put the
binary into the target: SPL can be copied as MLO on the SD-Card. Tom,
what do you think ?

Best regards,
Stefano

I think Thomas raises a good point.  The important thing is that 'make
fooboard' produces everything to boot the board (when possible).  But
at the end of the day, it comes down to the user needs to understand
how to boot their board.  The TI MLO file can be dd'ed to an SD card
and booted too, for example.

[U-Boot] [NEXT PATCH v1 7/7] MX35: add support for woodburn board

[Stefano Babic]

The woodburn board is based on the MX35 SOC.
Support for both external (NOR) and internal
(SD Card) boot mode are added. It uses the
generic SPL framework to implement the internal boot
mode.

The following peripherals are supported:
	- Ethernet (FEC)
	- SD Card
	- NAND (16 Gb)
	- NOR Flash

In the internal boot mode, a simple imximage header
file is generated to set the address in internal RAM
where the SOC must copy the SPL code. The initial setup
is then demanded to the SPL itself.
