That patch regarding searching for a partition type that Tom accepted sorts that out. spl searches for the 0xA2 partition for the uboot.img when CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION_TYPE=y and CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_TYPE=0xa2. With that the uboot partition in raw mode can be anywhere.

I checked this patch series, it is in v8 and it hasn't integrate to mainline yet. I will working my patches on top of this patch series, is it okay?
It's fine. Dalon, what's the status here ?
Frankly, i would just ignore that patch set. i will submit a new one that just moves directly to distro boot. sorry for the fuss.
--dalon
i would look at this patch set though
[PATCH v9 0/2] SPL: Add support to boot a partition type
which also touches socfpga_common.h
From: Tien Fong Chee tien.fong.chee@intel.com
Add a defconfig file for Arria10, which does not include enabling SPL.

Use Makefile condition to exclude this from being compiled altogether.

The Arria10 device will not be able to re-use the GEN5 SDRAM controller, so we shouldn't build the driver. Move CONFIG_ALTERA_SDRAM to Kconfig option in drivers/ddr/altera/Kconfig.

Uh, wrap this into 3/28 ? You added this stuff earlier in the patchset only to remove it now ...

There is no dependency on doing a separate clrbits first in the dwmac_deassert_reset function. Combine them into a single clrsetbits call.

I don't think this patch is correct. The purpose of using these calls separately is so that the write with cleared physel mask actually reaches hardware, followed by read and another write with the physel mask set. clrsetbits will do only one read-modify-write cycle.

I checked the code in linux driver, it only need one read-modify-write. So, the new code should be fine.

The original code does TWO writes into the hardware (one with zeroed physel mask, the other with configured physel mask), the new code does ONE write into the hardware. Why ? Is that because of some special hardware property ? Or is one write really fine ?

On the Arria10, the EMAC phy mode configuration for each EMACs is located in separate registers versus being in 1 register for the GEN5 devices. The Arria10 also has 3 EMACs compared to 2 for the GEN5 devices.
Update the dwmac_deassert_reset function to support both GEN5 and Arria10 devices.

IMO it'd be better to have a "proxy" reset manager header, which would include either rst-mgr-gen5.h or rst-mgr-a10.h depending on the type of SoC used. That way you'd be able to avoid this ifdeffering in each file including rst-mgr-*h

You might want to consider separate clock manager for A10 and Gen5 to avoid the massive ifdeffery.
Yes, I will separate them to separate files.

We can't provide this info to user now, because software can't read back or know the frequency of it now.

gd->bd->bi_ddr_freq = 0;What ? This cannot work ...
For A10, ddr controller is on fpga side and we don't need the ddr freq for ddr setup.
And if the user wants to know ? Any chance we can pass this info to the user ? I presume this is still a hard-IP controller, not some soft core thing ...
We can't provide this info to user now, because software can't read back or know the frequency of it now.
Not even from the handoff files ? Hm, ok, too bad.
