Can you send the value of SCR you found at SPL entry? This will clarify
what's enabled and what's not.
I would like to try that on my board as well for comparison. Could you
please tell me how this register can be read? In the ARM manuals SCR
seems to have several meanings... Thank you!

If you have a JTAG based debugger that has the capability of displaying
CP15 registers, look for "CP15 System Control Register". Otherwise you
will have to read it using an assembly instruction like below:
mrc p15, 0, r0, c1, c0, 0
After this instruction r0 will contain the SCR value. arm926ejs/start.S
has this instruction at line #367. You can put a breakpoint after this
and look at r0.

Aneesh
