Re: [U-Boot] [PATCH 1/1] trace: conserve gd register

An UEFI application may change the value of the register that gd lives in. But some of our functions like get_ticks() access this register. So we have to set the gd register to the U-Boot value when entering a trace point and set it back to the application value when exiting the trace point.
