The crash at dwc3 driver observed due to offset misalignment of structure members across files causing wrong code generation and leads to crash, the issue is found during dfu test.
For instance, ther is is mismatch in code generation to access the address of structure member dwc->dep[0] in gadget.c and ep0.c. This leads to NULL pointer reference casuing the crash. The inclusion of common.h fixes the issue.
The crash occurs due to below commit[1], revert of this patch resolves the issue.
[1] commit 95ebc253e6d4a3370e3dab14743bfc99fcd9cf1b Author: Masahiro Yamada yamada.masahiro@socionext.com Date: Tue Jun 28 10:48:40 2016 +0900
types.h: move and redefine resource_size_t
Currently, this is only defined in arch/arm/include/asm/types.h, so move it to include/linux/types.h to make it available for all architectures.
I defined it with phys_addr_t as Linux does. I needed to surround the define with #ifdef __KERNEL__ ... #endif to avoid build errors in tools building. (Host tools should not include <linux/types.h> in the first place, but this is already messy in U-Boot...)
