+Subject: [PATCH 06/40] microblaze: 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.

+Subject: [PATCH 07/40] upstream change to garbage collection sweep causes mb
+ regression
+
+Upstream change for PR13177 now clears the def_regular during gc_sweep of a
+section. (All other archs in binutils/bfd/elf32-*.c received an update
+to a warning about unresolvable relocations - this warning is not present
+in binutils/bfd/elf32-microblaze.c, but this warning check would not
+prevent the error being seen)
+
+The visible issue with this change is when running a c++ application
+in Petalinux which links libstdc++.so for exception handling it segfaults
+on execution.
+
+This does not occur if static linking libstdc++.a, so its during the
+relocations for a shared lib with garbage collection this occurs

+Subject: [PATCH 08/40] Fix bug in TLSTPREL Relocation
+
+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 10/40] Add new bit-field instructions
+
+This patches adds new bsefi and bsifi instructions.
+BSEFI- The instruction shall extract a bit field from a
+register and place it right-adjusted in the destination register.
+The other bits in the destination register shall be set to zero
+BSIFI- The instruction shall insert a right-adjusted bit field
+from a register at another position in the destination register.
+The rest of the bits in the destination register shall be unchanged
+

++
++   This function does not have to worry about setting the reloc
++   address or the reloc symbol index.
++
++   LOCAL_SYMS is a pointer to the swapped in local symbols.
++
++   LOCAL_SECTIONS is an array giving the section in the input file
++   corresponding to the st_shndx field of each local symbol.
++
++   The global hash table entry for the global symbols can be found
++   via elf_sym_hashes (input_bfd).
++
++   When generating relocatable output, this function must handle
++   STB_LOCAL/STT_SECTION symbols specially.  The output symbol is
++   going to be the section symbol corresponding to the output
++   section, which means that the addend must be adjusted

+
+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.
