Should one be able to run top of the linux-next on MX28 EVK hardware
with DT support enabled?
I have attached boot log I see when I try to do that.
Further if one enables, CONFIG_MTD_NAND_GPMI_NAND=y
CONFIG_MTD_NAND_PLATFORM=y code in
drivers/mtd/nand/gpmi-nand/gpmi-nand.c doesn't compile because of this code:
pinctrl = devm_pinctrl_get_select_default(&pdev->dev);
if (IS_ERR(pinctrl)) {
ret = PTR_ERR(pinctrl);
goto exit_pin;
}

Yes, I'm running it well with next-20120516.

One thing from the boot log worth checking is
[ 0.820000] stmp_reset_block(f5010000): module reset timeout
My wild guess is stmp_reset_block call on mmc0 failed on your end.

Thanks for reporting it. It's my bad. I thought I had mxs_defconfig
build testing cover the change. Actually, the gpmi is not enabled in
mxs_defconfig yet. I will send the following fix to Arnd and Olof soon.

Could you please confirm next-20120517 also boots?
I am not getting nothing on console.
This is my U-boot setup:
run netargs; tftpboot 42000000 uImage; tftpboot 42800000
imx28-evk.dtb; bootm 0x4000000 - 0x42000000

The addresses in bootm mismatch the ones in tftpboot?

Sorry, my typo. The line I use is:
run netargs; tftpboot 42000000 uImage; tftpboot 42800000
imx28-evk.dtb; bootm 0x42000000 - 0x42800000
This is what I see:

The next-20120517 seems working for me too.
You can turn on low-level debug option to see where it goes wrong
at your end.

Ok, so I changed the bootloader to U-boot 2012.04.01 +
CONFIG_OF_LIBFDT, and now it boots fine.
Thanks,

Rebase your uboot on top of git://git.denx.de/u-boot-arm.git -master . u-boot-
imx is missing a patch and won't be updated for next 3 weeks (maintainer is on
vacation). u-boot-arm has a bugfix for this issue

I followed the subsequent discussion on this, looks like most of you are
booting your kernels with uBoot.
We are using linux_prep bootlets from freescale to boot linux kernel.
I have following options turned on in my setup
CONFIG_ARM_APPENDED_DTB=y
CONFIG_ARM_ATAG_DTB_COMPAT=y
I am building imx28-evk.dtb and appending it to zImage as in:
make imx28-evk.dtb
cat zImage imx28-evk.dtb > zImage_w_dtb
We will investigate this further and let you know what I find, would be
glad to hear if anybody else is using MXS platform with appended device
tree.

Hm actually ... does anyone have dts file for mx28 with enabled GPMI nand? Looks
like that thing from example doesn't work (had to replace gpmi-nand with gpmi),
then it stopped complaining about clock. But now it dies on ecc.strength not
being set. MMC doesn't probe either etc.

Huang Shijie (Cc-ed) might be interested in knowing and fixing those,
but probably during v3.5-rc.

Are you using next-20120516 or later?

I guess you are not running Freescale imx28-evk board. Can you post
