4Subject: [PATCH 33/38] Add initial port of linux gdbserver add
5 gdb_proc_service_h to gdbserver microblaze-linux
6
7gdbserver needs to initialise the microblaze registers
8
9other archs use this step to run a *_arch_setup() to carry out all
10architecture specific setup - may need to add in future
11
12 * add linux-ptrace.o to gdbserver configure
13 * Update breakpoint opcode
14 * fix segfault on connecting gdbserver
15 * add microblaze_linux_memory_remove_breakpoint
16 * add set_solib_svr4_fetch_link_map_offsets
17 * add set_gdbarch_fetch_tls_load_module_address
18 * Force reading of r0 as 0, prevent stores
