When you see the repeating C's, I believe that is the ROM not finding
u-boot. You have an issue with the mailbox drivers
I use the following mailbox values for my kernel config
CONFIG_MAILBOX=y # CONFIG_OMAP_MBOX is not set # CONFIG_OMAP2PLUS_MBOX
is not set # CONFIG_OMAP_MBOX_KFIFO_SIZE is not set
The davinci mdio driver should report a phymask and that value is used to
update the device tree.
I load the following drivers in the following order.
libphy
smsc
davinci_cpdma
davinci_mdio
ti_cpsw
I also remove the second phy slave from the device tree.
I would verify your device tree blob has the correct values for your pin
setup.
