      ARM: 7750/1: update legacy CPU ID in decompressor cache support jump table · ced2a3b8
      Marc C 提交于
      The previous mask values for the legacy ARM CPU IDs were conflicting
      with the CPU ID assignments for late-generation CPUs (like the
      Qualcomm MSM/QSD or Broadcom Brahma-15 processors). This change
      corrects the legacy ARM CPU ID value so that the jump table can
      fall-through to the appropriate cache maintenance / MMU functions.

      ARM: 7743/1: compressed/head.S: work around new binutils warning · da94a829
      Arnd Bergmann 提交于
      In August 2012, Matthew Gretton-Dann checked a change into binutils
      labelled "Error on obsolete & warn on deprecated registers", apparently as
      part of ARMv8 support. Apparently, this was supposed to emit the message
      "Warning: This coprocessor register access is deprecated in ARMv8" when
      using certain mcr/mrc instructions and building for ARMv8. Unfortunately,
      the message that is actually emitted appears to be '(null)', which is
      less helpful in comparison.
      
      Even more unfortunately, this is biting us on every single kernel
      build with a new gas, because arch/arm/boot/compressed/head.S and some
      other files in that directory are built with -march=all since kernel
      commit 80cec14a "[ARM] Add -march=all to assembly file build in
      arch/arm/boot/compressed" back in v2.6.28.
      
      This patch reverts Russell's nice solution and instead marks the head.S
      file to be built for armv7-a, which fortunately lets us build all
      instructions in that file without warnings even on the broken binutils.
      
      Without this patch, building anything results in:

      ARM: 7737/1: fix kernel decompressor compilation error with CONFIG_DEBUG_SEMIHOSTING · 27523679
      Nicolas Pitre 提交于
      Selecting this option produces:
      
        AS      arch/arm/boot/compressed/debug.o
      arch/arm/boot/compressed/debug.S:4:33: fatal error: mach/debug-macro.S: No such file or directory
      compilation terminated.
      make[3]: *** [arch/arm/boot/compressed/debug.o] Error 1
      
      The semihosting support cannot be modelled into a senduart macro as
      it requires memory space for argument passing.  So the
      CONFIG_DEBUG_LL_INCLUDE may not have any sensible value and the include
      directive should be omitted.
      
      While at it, let's add proper semihosting output support to the
      decompressor.
