+Subject: [PATCH 05/43] [LOCAL]: Fixup debug_loc sections after linker
+ relaxation Adds a new reloctype R_MICROBLAZE_32_NONE, used for passing reloc
+ info from the assembler to the linker when the linker manages to fully
+ resolve a local symbol reference.
 
 This is a workaround for design flaws in the assembler to
 linker interface with regards to linker relaxation.

 Fixed the problem related to the fixup/relocations TLSTPREL.
 When the fixup is applied the addend is not added at the correct offset
 of the instruction. The offset is hard coded considering its big endian
 and it fails for Little endian. This patch allows support for both
 big & little-endian compilers

+Subject: [PATCH 32/43] Add initial port of linux gdbserver add
+ gdb_proc_service_h to gdbserver microblaze-linux
+
+gdbserver needs to initialise the microblaze registers
+
+other archs use this step to run a *_arch_setup() to carry out all
+architecture specific setup - may need to add in future
+
+ * add linux-ptrace.o to gdbserver configure
+ * Update breakpoint opcode
+ * fix segfault on connecting gdbserver
+ * add microblaze_linux_memory_remove_breakpoint
+ * add set_solib_svr4_fetch_link_map_offsets
+ * add set_gdbarch_fetch_tls_load_module_address
+ * Force reading of r0 as 0, prevent stores

+
+For Microblaze linux toolchains, set the build_gdbserver=yes
+to allow driving gdbserver configuration from the upper level
+
+This patch has been absorbed into the original patch to add
+linux gdbserver support for Microblaze.

+Subject: [PATCH 44/45] gdb/microblaze-linux-nat.c: Fix target compilation of
+ gdb
+
+Add the nat to the configure file
+
+Remove gdb_assert.h and gdb_string.h.
+
+Adjust include for opcodes as well.
+
+Update to match latest style of components, similar to ppc-linux-nat.c
+
+Update:
+  get_regcache_arch(regcache) to regcache->arch()
+  regcache_raw_supply(regcache, ...) to regcache->raw_supply(...)
+  regcache_raw_collect(regcache, ...) to regcache->raw_collect(...)
