When downloading a firmware into a big flash partition the erase
operation can take a long time to be complete from few seconds to
minutes in extreme cases. During the erase the DFU gadget does not
respond to any USB setup request, the host only see a stalled USB
endpoint and cannot get responses
The gadget driver set the bInterfaceProtocol value to 1 in the DFU
interface descriptor. However this value is used to indicate that the
gadget is in run-time mode and not ready for DFU. When ready for DFU
operation the bInterfaceProtocol value must be set to 2 (DFU mode).
>From the DFU 1.1
Global variables must be reset to their default value before a new
dfu_bind is done. Otherwise things wont work and are likely to cause
a system crash due to a use after free: the global dfu_files was still
pointing deallocated structure after unbind.

Hi,
The two first patch are focused on two fixes for an issue I encountered
when trying to use the DFU gadget on big flash partition (2MB).
You can find more information in each patch, but here is a short summary
of the issue:

These changes introduce support for Grinn i.MX6ULL liteBoard revision.
There are no other changes except the CPU therefore the existing
board directory was used.

Hi,
I'm having problems booting a linux kernel image on an imx7d.
What I want is to boot in nonsecure mode and that the kernel enables the
second core with the PSCI.
What I see is that barebox crashes within the call to __mmu_cache_on()
in the file arch/arm/cpu/sm.c:

Right, thanks for noting. Fixed.
