| * | sh: Integrate the SH-5 onchip_remap() more coherently.Paul Mundt2009-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently this is special-cased for early initialization. While there are situations where these static early initializations are still necessary, with minor changes it is possible to use this for the regular ioremap implementation as well. This allows us to kill off the special-casing for the remap completely and to start tidying up all of the SH-5 special-casing in drivers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * | sh: Kill off the now unused ARCH_USES_GETTIMEOFFSET code.Paul Mundt2009-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the stragglers (MTU2/CMT/etc.) have been rewritten and we are selecting both GENERIC_TIME and GENERIC_CLOCKEVENTS, the get_offset() timer op is completely unused. As a result, we are now able to kill off the ARCH_USES_GETTIMEOFFSET references. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: remove old MTU2 driverMagnus Damm2009-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the old MTU2 driver (CONFIG_SH_MTU2/timer-mtu2.c) As replacement, select the sh_cmt driver with CONFIG_SH_TIMER_MTU2 and configure timer channel using platform data. If multiple MTU channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_mtu2.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

* | | flat: fix data sections alignmentOskar Schirmer2009-05-29
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flat loader uses an architecture's flat_stack_align() to align the stack but assumes word-alignment is enough for the data sections. However, on the Xtensa S6000 we have registers up to 128bit width which can be used from userspace and therefor need userspace stack and data-section alignment of at least this size. This patch drops flat_stack_align() and uses the same alignment that is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's not defined by the architecture. It also fixes m32r which was obviously kaput, aligning an uninitialized stack entry instead of the stack pointer.

| * sh: Fix up DSP context save/restore.Michael Trimarchi2009-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a number of issues with the DSP context save/restore code, mostly left-over relics from when it was introduced on SH3-DSP with little follow-up testing, resulting in things like task_pt_dspregs() referencing incorrect state on the stack. This follows the MIPS convention of tracking the DSP state in the thread_struct and handling the state save/restore in switch_to() and finish_arch_switch() respectively. The regset interface is also updated, which allows us to finally be rid of task_pt_dspregs() and the special cased task_pt_regs().
