      microblaze: Add support for CCF · c1120542
      Michal Simek authored 
      
Add support for CCF for Microblaze.

Old binding:
system_timer: system-timer@41c00000 {
	clock-frequency = <75000000>;
	...
}

New binding:
system_timer: system-timer@41c00000 {
	clocks = <&clk_bus>;
	...
}

Both should be supported for a while

Microblaze clock binding:
clocks {
	#address-cells = <1>;
	#size-cells = <0>;
	clk_bus: bus {
		#clock-cells = <0>;
		clock-frequency = <75000000>;
		clock-output-names = "bus";
		compatible = "fixed-clock";
		reg = <1>;
	} ;
	clk_cpu: cpu {
		#clock-cells = <0>;
		clock-frequency = <75000000>;
		clock-output-names = "cpu";
		compatible = "fixed-clock";
		reg = <0>;
	} ;
} ;

      Make most arch asm/module.h files use asm-generic/module.h · 786d35d4
      David Howells authored 
      
Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
into asm-generic/module.h for all arches bar MIPS.

Also, use the generic definition mod_arch_specific where possible.

To this end, I've defined three new config bools:

 (*) HAVE_MOD_ARCH_SPECIFIC

     Arches define this if they don't want to use the empty generic
     mod_arch_specific struct.

 (*) MODULES_USE_ELF_RELA

     Arches define this if their modules can contain RELA records.  This causes
     the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
     defined by the arch rather than have the core emit an error message.

 (*) MODULES_USE_ELF_REL

     Arches define this if their modules can contain REL records.  This causes
     the Elf_Rel mapping to be emitted and allows apply_relocate() to be
     defined by the arch rather than have the core emit an error message.

Note that it is possible to allow both REL and RELA records: m68k and mips are
two arches that do this.

With this, some arch asm/module.h files can be deleted entirely and replaced
with a generic-y marker in the arch Kbuild file.

Additionally, I have removed the bits from m32r and score that handle the
unsupported type of relocation record as that's now handled centrally.

      microblaze: Do not select GENERIC_GPIO by default · 59516b07
      Lars-Peter Clausen authored 
      
The microblaze architecture does not provide a native GPIO API implementation
nor requires GPIOLIB, but still selects GENERIC_GPIO by default. As a result the
following build error occurs, if GPIOLIB is not selected:

	include/asm-generic/gpio.h: In function 'gpio_get_value_cansleep':
	include/asm-generic/gpio.h:218: error: implicit declaration of function '__gpio_get_value'
	include/asm-generic/gpio.h: In function 'gpio_set_value_cansleep':
	include/asm-generic/gpio.h:224: error: implicit declaration of function '__gpio_set_value'

This patch addresses the issue by not selecting GENERIC_GPIO by default. This
causes the GPIO API to be stubbed out if no implementation is provided.

      microblaze: generic atomic64 support · eacb6ec9
      Daniel Borkmann authored 
      
This tiny patch adds generic atomic64 support for the Microblaze
architecture.

The patch is against the latest linux-2.6-microblaze tree. It also
fixes the kernel build for microblaze:

Error log:

      microblaze: switch to GENERIC_PCI_IOMAP · 1b34d160
      Michael S. Tsirkin authored 
      
microblaze copied pci_iomap from generic code, probably to avoid
pulling the rest of iomap.c in.  Since that's in
a separate file now, we can reuse the common implementation.

The only difference is handling of nocache flag,
that turns out to be done correctly by the
generic code since arch/microblaze/include/asm/io.h
defines ioremap_nocache same as ioremap.
