Thanks, that helped quite a bit. After inserting various print
statements, I found that the system is hanging in the readl call in
orion_pcie_dev_id. The call chain is:
The readl is attempting to access the address
KIRKWOOD_REGS_VIRT_BASE + 0x40000.
This same code gets executed successfully when the kernel is started
from u-boot; I'm not sure what's different in the post-kexec
environment. Any suggestions on what to try next would be
