[meta-xilinx] Kernel (linux-xlnx) hangs when trying to mount root (SD card & NFS)

[Kleve, Jesse R]

I looked through this wiki page and followed it exactly. I noticed a different in the expected output vs what I'm getting. Does this indicate anything to you or anyone else?

http://www.wiki.xilinx.com/SD+controller

Expect output:
sdhci: Secure Digital Host Controller Interface driver
sdhci: Copyright(c) Pierre Ossman
sdhci-pltfm: SDHCI platform and OF driver helper
sdhci-arasan ff160000.sdhci: No vmmc regulator found
sdhci-arasan ff160000.sdhci: No vqmmc regulator found
mmc0: SDHCI controller on ff160000.sdhci [ff160000.sdhci] using ADMA 64-bit
sdhci-arasan ff170000.sdhci: No vmmc regulator found
sdhci-arasan ff170000.sdhci: No vqmmc regulator found
mmc1: SDHCI controller on ff170000.sdhci [ff170000.sdhci] using ADMA 64-bit
........
mmc0: new high speed SDHC card at address 1234
mmcblk0: mmc0:1234 SA04G 3.63 GiB
mmc0: Got data interrupt 0x00000002 even though no data operation was in progress.
mmcblk0: p1
.........
mmc1: new high speed SDHC card at address aaaa
mmcblk1: mmc1:aaaa SU08G 7.40 GiB
mmcblk1: p1

My output is as follows:
[    2.793138] sdhci: Secure Digital Host Controller Interface driver
[    2.799239] sdhci: Copyright(c) Pierre Ossman
[    2.803650] sdhci-pltfm: SDHCI platform and OF driver helper
[    2.809445] sdhci-arasan ff170000.sdhci: could not find pctldev for node /reset-controller, deferring probe

    Check this link, I think u-boot bootargs needs to be changed for SD boot
