      x86, earlyprintk: Add earlyprintk for Intel Moorestown platform · c20b5c33
      Feng Tang 提交于
      Intel Moorestown platform has a spi-uart device(Maxim3110),
      which connects to a Designware spi core controller. This patch
      will add early console function based on it.
      
      As it will be used long before Linux spi subsystem get
      initialised, we simply directly manipulate the spi controller's
      register to acheive the early console func. This is safe as it
      will be disabled when devices subsytem get initialised.
      
      To use it, user need enable CONFIG_X86_MRST_EARLY_PRINTK in
      kenrel config and add "earlyprintk=mrst" in kernel command line.

      x86: Add two helper macros for fixed address mapping · 5a47c7da
      Feng Tang 提交于
      Sometimes fixmap will be used to map an physical address which
      is not PAGE align, so to use it we need first map it and then
      add the address offset to the mapped fixed address. These 2 new
      helpers are suggested by Ingo Molnar to make the process
      simpler.
      
      For a physicall address like "phys", a directly usable virtual
      address can be get by
      	virt = (void *)set_fixmap_offset(fixed_idx, phys);
      or
      	virt = (void *)set_fixmap_offset_nocache(fixed_idx, phys);
      (depends on whether the physical address is cachable or not).

      x86, mrst: A function in a header file needs to be marked "inline" · 55572b29
      H. Peter Anvin 提交于
      A function in a header file needs to be explicitly marked "inline", or
      gcc will complain if it is not used.
