In these SoCs it's possible to control LEDs both as GPIOs or by hardware.
However, on some devices there are Serial LEDs (LEDs connected to a 74x164

Some of these Serial LEDs are hardware controlled (e.g. ethernet LEDs) and
exporting the 74x164 as spi-gpio prevents those LEDs to be hardware
controlled, so the only chance to keep them working is by using this driver.

When ptracing system calls (PTRACE_SYSCALL), the pt_regs.trap value contains
the system call type that can be used to distinguish between sc and scv 0
system calls, and the different register conventions can be accounted for.
If the value of (pt_regs.trap & 0xfff0) is 0xc00 then the system call was
