      ARM: OMAP1: fix USB configuration use-after-release · 07fd296d
      Aaro Koskinen authored
      All boards, except Amstrad E3, mark USB config with __initdata.
      
      As a result, when you compile USB into modules, they will try to refer
      already released platform data and the behaviour is undefined. For example
      on Nokia 770, I get the following kernel panic when modprobing ohci-hcd:

      Merge tag 'omap-fixes-a2-for-v3.8-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8-rc2/fixes
      
      Some OMAP PRCM and sparse fixes against v3.8-rc1.  A basic set of test
      logs are available here:
      
          http://www.pwsan.com/omap/testlogs/prcm_fixes_b_3.8-rc/20130102120724/
      
      The 3730 Beagle XM here has an intermittent failure mounting SD root,
      but the suspicion right now is that this is due to a failing SD card,
      rather than any change introduced by these patches.
      
      This second version includes a few changes requested by Tony Lindgren.

      ARM: OMAP: SRAM: resolve sparse warnings · 9fbe7c24
      Paul Walmsley authored
      Commit bb772094 ("ARM: OMAP: Move
      omap2+ specific parts of sram.c to mach-omap2") adds some new sparse
      warnings:
      
      arch/arm/plat-omap/sram.c:43:6: warning: symbol 'omap_sram_push_address' was not declared. Should it be static?

      arch/arm/plat-omap/sram.c:73:13: warning: symbol 'omap_map_sram' was not declared. Should it be static?
      
      This second version fixes the warnings by including <plat/sram.h>, at
      Tony's request.

        Here are few more patches to finish the omap changes for multiplatform
