2008-01-28sh: Add a SUPERH32 config symbol.Paul Mundt
We need to differentiate from SUPERH64, so add a SUPERH32 for regular sh. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: Move CPU subtypes to Kconfig.sh.Paul Mundt

2008-01-24Driver core: change sysdev classes to use dynamic kobject namesKay Sievers
All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-01-24Kobject: convert arch/* from kobject_unregister() to kobject_put()Greg Kroah-Hartman
There is no need for kobject_unregister() anymore, thanks to Kay's kobject cleanup changes, so replace all instances of it with kobject_put(). Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-01-24Kobject: change arch/sh/kernel/cpu/sh4/sq.c to use kobject_init_and_addGreg Kroah-Hartman
Stop using kobject_register, as this way we can control the sending of the uevent properly, after everything is properly initialized. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-11-30sh: Support PCI IO access of SH7780 base boards.Nobuhiro Iwamatsu
The IO access of PCI is not supported in R7780RP and the MS7780SE board now. The support of the IO access mode of e100 and a lot of IDE chips becomes possible by fixing the code. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-30sh: Fix PCI IO space base address of SH7780.Nobuhiro Iwamatsu
PCI IO space base address of SH7780 was wrong. Change from 0xFE400000 to 0xFE200000. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-23sh: include ax88796 in the defconfig for r7785rpMagnus Damm
This patch adds the ax88796 device driver to the r7785rp defconfig. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-23sh: include ax88796 in the defconfig for r7780mpMagnus Damm
This patch adds the ax88796 device driver to the r7780mp defconfig. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-23sh: fix R2D-1 CF supportMagnus Damm
This patch fixes CF support for R2D-1 boards. Both R2D-1 and R2D-PLUS are equipped with CF IRQs, but the R2D-1 FPGA version seem to deliver IRQ spikes with certain CF cards during libata probing. This patch enables polling for R2D-1 as a workaround for this broken FGPA logic. R2D-1 CF support was recently introduced by commit: 43f4b8c7578b928892b6f01d374346ae14e5eb70.

2007-11-19sh: lockless UTLB miss fast-path.Paul Mundt
With the refactored update_mmu_cache() introduced in older kernels, there's no longer any need to take the page_table_lock in this path, so simply drop it completely. Without this, performance degradation is seen on SMP on heavily threaded workloads that don't use the split ptlock, and ultimately we have no reason to contend for the lock in the first place. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-19sh: Kill off UTLB flush in fast-path.Paul Mundt
The __do_page_fault() fast-path contains a UTLB flush in order to force an ITLB reload, this isn't needed in practice as the ITLB is auto-reloaded from the UTLB anyways, which is already displaced by the manual 'ldtlb' in the update_mmu_cache() path. This provides a measurable speed up in the TLB miss fast-path. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-08Merge branch 'page_colouring_despair'Paul Mundt
2007-11-08sh: Kill off broken snapgear ds1302 code.Paul Mundt
This will force the snapgear boards to use the on-chip SH RTC instead, until the rtc-ds1302 driver is merged. The current code is broken and hasn't built in some time, so just kill it off and get the board working again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Fix heartbeart on Solution Engine seriesNobuhiro Iwamatsu
Access size to LED is not added on Solution Engine series. LED doesn't work. Fixed this problem. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: hs7751rvoip: Kill off dead IPR IRQ mappings.Paul Mundt
This is dead code, and doesn't build anyways. Kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: hs7751rvoip: irq.c needs linux/interrupt.h.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Kill off __{copy,clear}_user_page().Paul Mundt
Now that copy_to_user_page()/copy_from_user_page() are wired up, we can drop the old __copy_xxx() implementations. Now that the page colouring scheme has changed via kmap_coherent(), we can avoid the flush in these specific helpers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Optimized copy_{to,from}_user_page() for SH-4.Paul Mundt
This moves copy_{to,from}_user_page() out-of-line on SH-4 and converts for the kmap_coherent() API. Based on the MIPS implementation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Wire up clear_user_highpage().Paul Mundt
With the kmap_coherent() API in place, this is trivial to implement, and lets us avoid the cache flush in certain cases. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Kill off the remaining ST40 cruft.Paul Mundt
The ST40 stuff in-tree hasn't built for some time, and hasn't been updated for over 3 years. ST maintains their own out-of-tree changes and rebases occasionally, and that's ultimately where all of the ST40 users go anyways. In order for the ST40 code to be brought up to date most of the stuff removed in this changeset would have to be rewritten anyways, so there's very little benefit in keeping the remnants around either. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Export __{s,u}divsi3_i4i on all CPUs.Paul Mundt
Currently these are only being exported for CONFIG_CPU_SH4. This invariably breaks when building for an SH-3 that includes multiple targets in multilib. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Fix up kgdb-on-NMI branch target.Paul Mundt
This was all reworked some time ago, the old debug_enter was ripped out with everything going through a debug trap jump table instead. Kill off the debug_enter target and reference kgdb_handle_exception directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: ubc wakeup for SH-4 only.Paul Mundt
SH-4A parts generally don't have any use for this, and it requires an alternate implementation anyways. Leave this as an SH-4 only option, as that's the only place this has been needed in the past. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Fix compression method when making uImage.Nobuhiro Iwamatsu
When uImage is made by using 'make uImage', zImage is used. If zImage is used, the compression method need not be set. However, it is set for "gzip" for a compression method. I corrected to set "none". Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Kill off duplicate includes.Paul Mundt
Caught by the surprisingly not-entirely-useless 'includecheck'. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Add SH7705 and other to the support of Solution Engine.Nobuhiro Iwamatsu
This patch supports Hitachi Solution Engine (SuperH) of SH7705, SH7710, SH7712, SH7750S and SH7750R. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-11-02sh: mach-type updates.Paul Mundt
This adds in the x3proto and magicpanelr2 mach types, plugs in highlander and rts7751r2d groups, and also hooks up the r2d subtypes. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-02sh: Fix up r7780rp highlander CF access size.Paul Mundt
R7780RP can't do byte-sized accesses to CF, so needs to do word sized access with low-byte masking. This same problem exists on older versions of the R2D, with the same workaround having been implemented in 43f4b8c7578b928892b6f01d374346ae14e5eb70 there. Follow that change for the highlander boards. This does not impact R7780MP or SH7785 based Highlander modules. If you're unfortunate enough to be stuck with an R7780RP, this patch is for you!

2007-11-02sh: Terminate .eh_frame in VDSO with a 4-byte 0.Kaz Kojima
It's assumed that .eh_frame is terminated with 4-byte 0 in shared libraries and executable. It seems to be the case for VDSOs too. Without this terminator, I saw failures when unwinding from VDSO, though I don't know how other architectures handle this issue. For the normal libs, crtendS.o gives this terminator. We can use such terminating objects. Or we can add a 4-byte 0 with modifying the linker script like as the patch below.
