      sh: Tidy up SH-4A boot_cpu_data.flags probing. · 0bf8513e
      由 Paul Mundt 提交于 
      This tidies up the boot_cpu_data.flags probing on SH-4A. All of them have
a few things in common, which we can blindly set, rather than having each
subtype have to set the same flags. We can also make assumptions about
cache ways and the validity of PTEA, so this also kills off CPU_HAS_PTEA
as a config option. There was also a bug in the FPU probing, which is now
tidied up.

      sh: clkfwk: Make clock-cpg usable for non-legacy platforms. · 36aa1e32
      由 Paul Mundt 提交于 
      This adds a new SH_CLK_CPG for parts that have CPG support.
SH_CLK_CPG_LEGACY is made to depend on this, and still needs to be set
for platforms that want clock-cpg to register the legacy clocks. With
this new config item in place, it is now possible to start layering more
generic CPG code in place while other platforms transition off of the
legacy clocks.

      sh: remove old CMT driver · f425752f
      由 Magnus Damm 提交于 
      This patch removes the old CMT driver (CONFIG_SH_CMT/timer-cmt.c)

As replacement, select the sh_cmt driver with CONFIG_SH_TIMER_CMT
and configure timer channel using platform data.

If multiple CMT channels are enabled using platform data, use the
earlytimer parameter on the kernel command line to select channel.
For instance, use "earlytimer=sh_cmt.0" to select the first channel.

To verify which timer is being used, look at printouts or the timer
irq count in /proc/interrupts.

      sh: add kexec jump support · b7cf6ddc
      由 Magnus Damm 提交于 
      Add kexec jump support to the SuperH architecture.

Similar to the x86 implementation, with the following
exceptions:

- Instead of separating the assembly code flow into
two parts for regular kexec and kexec jump we use a
single code path. In the assembly snippet regular
kexec is just kexec jump that never comes back.

- Instead of using a swap page when moving data between
pages the page copy assembly routine has been modified
to exchange the data between the pages using registers.

- We walk the page list twice in machine_kexec() to
do and undo physical to virtual address conversion.

      sh: Support for extended ASIDs on PTEAEX-capable SH-X3 cores. · 8263a67e
      由 Paul Mundt 提交于 
      This adds support for extended ASIDs (up to 16-bits) on newer SH-X3 cores
that implement the PTAEX register and respective functionality. Presently
only the 65nm SH7786 (90nm only supports legacy 8-bit ASIDs).

The main change is in how the PTE is written out when loading the entry
in to the TLB, as well as in how the TLB entry is selectively flushed.

While SH-X2 extended mode splits out the memory-mapped U and I-TLB data
arrays for extra bits, extended ASID mode splits out the address arrays.
While we don't use the memory-mapped data array access, the address
array accesses are necessary for selective TLB flushes, so these are
implemented newly and replace the generic SH-4 implementation.

With this, TLB flushes in switch_mm() are almost non-existent on newer
parts.

      sh: SuperH Mobile suspend support · 77594912
      由 Magnus Damm 提交于 
      This patch contains CONFIG_SUSPEND support to the SuperH
architecture. If enabled, SuperH Mobile processors will
register their suspend callbacks during boot.

To suspend, use "echo mem > /sys/power/state". To allow
wakeup, make sure "/sys/device/platform/../power/wakeup"
contains "enabled". Additional per-device driver patches
are most likely needed.
