I've now branched from u-boot-dm.git/zynq-working2 and then merged
u-boot-spi/master into it.
After a few merge conflicts i'am able to build u-boot and boot it from
SD with working DM support during SPL and QSPI support.
The next step was/is burning this file into the QSPI flash and boot
from it.
burning was now problem, but boot ends up with:
U-Boot SPL 2015.10-rc4-00101-gb6dcb3f-dirty (Oct 08 2015 - 08:42:53)
qspi boot
boot device - 8
uclass_find_device_by_seq: 0 0
- not found
uclass_find_device_by_seq: 1 0
- not found
Invalid bus 0 (err=-19)
SPI probe failed.
### ERROR ### Please RESET the board ###
maybe there is yet another switch, which needs to be turned on.
Subject of suspicion is currently "support simple-bus driver in SPL".
But if i compile with this option,
boot ends up with:
U-Boot SPL 2015.10-rc4-00101-gb6dcb3f-dirty (Oct 08 2015 - 09:01:35)
mmc boot

spl: mmc: no boot mode left to try
### ERROR ### Please RESET the board ###
This is because there is only very limited heap (0x1000) enabled in
zynq-common.h and therefore the FAT buffers cannot be allocated -> solved.
Further i've found out that my board isn't booting from SPI because
there is nothing within "SPL-devicetree" about QSPI.
Can anyone explain me how the "normal" and the "SPL" devicetree is
separated ?
best regards,
Hannes
