[U-Boot] - Help with usb3503 hub enumeration

[Suriyan Ramasami]

Hello All and especially Dan Murphy,
    Reading thru the mailing list Dan seems to have worked on usb3503a +
LAN9730 enumeration wrt the OMAP5. Hence, I seek his help and anyone else!

   This is with regards to an odroid-u2. It is Exynos 4412 prime based. It
has a usb3503a hub and also a LAN 9730 - I am guessing pretty much like the
omap5.

  From the clock source and the PMIC perspective I do see that the usb3503a
is powered up and gets a REF_CLK. (I can verify this as I can read and
write via I2C to the usb3503a and get/set its configuration. Also, I do
have the correct GPIO pins for the INT_N, RESET_N and HUB_CONNECT wrt the
usb3503a.

  In the platform based ehci-exynos.c I do initialize the the USB_PHY,
HSIC_1_PHY and HSIC2_PHY that is present in the Exynos 4412 SoC. These I
have copied over from the Linux kernel (which has full usb support and
works). Once this is done, I can see that the values for hccr and hcor
appear correct as reported by Linux too.

  When it comes to starting up usb via usb start, I seem to hit the below
sequence - with debug on ... The u-boot is quite an older u-boot, but I
have ported most of the usb code over from the arndale port over at
insignal - which seems to have usb working (they too have a usb3503a but
with exynos5)

My question is how do I debug this to get it working. Looks like the hcd
does not see the usb3503a, am I correct?
