 - complete tracehook implementation
 - add syscall tracepoints support
 - add jumplabels support
 - add memtest support
 - drop unused/duplicated code from entry.S, ptrace.c, coprocessor.S,
   elf.h and syscall.h
 - clean up warnings caused by WSR/RSR macros
 - clean up DTC warnings about SPI controller node names in xtfpga.dtsi
 - simplify coprocessor.S
 - get rid of explicit 'l32r' instruction usage in assembly
