* sh: Solution Engine 7722 board support.Ryusuke Sakato2007-05-06
| | | | | | | | | This adds more full-featured support for the SH7722 Solution Engine. Previously this was using the generic board, and lacked most of the peripheral support. Signed-off-by: Ryusuke Sakato <sakato.ryusuke@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: L-BOX RE2 support.Nobuhiro Iwamatsu2007-05-06
| | | | | | | | | | | | | | | | This adds support for the L-BOX RE2 router. http://www.nttcom.co.jp/l-box/ L-BOX RE2 is a SH7751R-based router. It has CF, Cardbus, serial, and LAN x2. This is one of the very few SH boards that a general person can obtain now. The L-BOX shipped with a 2.4.28 kernel, this is a rewritten patch adding it to current git.

* sh: Add SH7785 Highlander board support (R7785RP).Paul Mundt2007-05-06
| | | | | | | | | | | This adds preliminary support for the SH7785-based Highlander board. Some of the Highlander support code is reordered so that most of it can be reused directly. This also plugs in missing SH7785 checks in the places that need it, as this is the first board to support the CPU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: generic BUG() support.Paul Mundt2007-05-06
| | | | | | | | | Wire up GENERIC_BUG for SH. This moves off of the special bug frame and on to the generic struct bug_entry. Roughly the same semantics are retained, and we can kill off some of the verbose BUG() reporting code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: speculative execution support for SH7780.Paul Mundt2007-05-06
| | | | | | | | | | SH7780 has a speculative execution mode where it can speculatively perform an instruction fetch for subroutine returns, this allows it to be enabled. There are some various pitfalls associated with this mode, so it's left as depending on CONFIG_EXPERIMENTAL and not enabled by default. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off dead bigsur and ec3104 boards.Paul Mundt2007-02-14

* sh: heartbeat consolidation for banked LEDs.Paul Mundt2007-02-13
| | | | | | | | | | | This consolidates the various board heartbeat LED implementations, used for strobing the load average across a LED bank. Those boards not implementing a full bank can hook in via the LED class. We leave the compat hook in the machvec for now until those non-banked boards are able to migrate to the drivers/leds.

* [PATCH] LOG2: Implement a general integer log2 facility in the kernelDavid Howells2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

* sh: sh775x/titan fixes for irq header changes.Jamie Lenehan2006-12-05
| | | | | | | | | | | | | | | | | | | | | The following moves the creation of IPR interupts into setup-7750.c and updates a few other things to make it all work after the "Drop CPU subtype IRQ headers" commit. It boots and runs fine on my titan board. - adds an ipr_idx to the ipr_data and uses a function in the subtype code to calculate the address of the IPR registers - adds a function to enable individual interrupt mode for externals in the subtype code and calls that from the titan board code instead of doing it directly. - I changed the shift in the ipr_data to be the actual # of bits to shift, instead of the numnber / 4 - made it easier to match with the manual.

* sh: Explicit endian selection support.Paul Mundt2006-12-05
| | | | | | | | | | | | Previously big endian was simply assumed if little endian was not set, which led to some cflags ordering issues. There's not much point to not having a big endian option, so shove one in a choice and wire it up in the Makefile. This lets us clean up some of the cflags ordering while we're at it.

* sh: First step at generic timeofday support.Paul Mundt2006-10-06
| | | | | | | | | | | | | At the moment we wrap GENERIC_TIME around our existing timer API. As boards start providing their own clocksources, they're able to select GENERIC_TIME accordingly and optimize out most of the timer API. Once the current timers have been reworked as proper clocksource drivers, the rest of the place holders for the timer API can go away and we can flip on GENERIC_TIME unconditionally.

* [PATCH] Configurable NODES_SHIFTYasunori Goto2006-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

* [PATCH] sh: Drop hp690 discontig supportPaul Mundt2005-11-07
| | | | | | | | | | | | | | | | There was only one board using this (hp690 specifically), and it just so happens that it's only physically discontiguous at the "normal" P1 offset. If we bump up the P1 offset, it's possible to hit a shadowed region of memory where we suddenly become magically contiguous. As people have been using this shadowed region workaround for quite some time (and without any adverse effects), it's time to drop the left over discontig bits that no longer have any practical use (it was always very much hp690-centric to begin with).

While we are at it, fixed several obvious cases when BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h are *not* going to have floppy.c compile, let alone work).
