sh: Fix PCI BAR address-space wraparound.

2007-03-12T05:50:49Z

When a SH7751R system includes a card that has wide range space like a graphics card, the pci-pci bridge controller can't set the correct address range. For example, when *lower_limit is 0xfd000000 and bar_size is 0x4000000, in the following code at arch/sh/drivers/pci/pci-auto.c, 0x0 is set in bar_value. pciauto_setup_bars() { ... bar_value = ((*lower_limit - 1) & ~(bar_size - 1)) + bar_size; ... *lower_limit = bar_value + bar_size; } As a result, 0x4000000 is set in *lower_limit, but this value is wrong. The following patch avoids this problem by checking the range of the value and refusing to update the BAR if the calculated value ends up being bogus.

sh: Kill off dead bigsur and ec3104 boards.

Neither of these have had any maintenance in years, and there's no interest in keeping them straggling along. These have already been slated for removal some time, so finally just get rid of them. Signed-off-by: Paul Mundt

sh: heartbeat consolidation for banked LEDs.

2007-02-13T06:42:28Z

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. Signed-off-by: Paul Mundt

sh: SH-DMAC compile fixes

2007-02-13T01:54:45Z

This patch does the following: - remove the make_ipr_irq stuff from dma-sh.c and replace it with a simple channel<->irq mapping table. - add DMTEx_IRQ constants for sh4 cpus - fix sh7751 DMAE irq number The SH7780 uses the same IRQs for DMA as other SH4 types, so I put the constants on top of the dma.h file. Other CPU types need to #define their own DMTEx_IRQ contants in their appropriate header. Signed-off-by: Manuel Lauss Signed-off-by: Paul Mundt

sh: push-switch fixups for work_struct API damage.

INIT_WORK() dropped the data arg, so now we have to stash an extra pointer and backpedal instead. Signed-off-by: Paul Mundt

sh: sh775x/titan fixes for irq header changes.

2006-12-06T03:05:02Z

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: dma-api channel capability extensions.

2006-12-06T01:45:39Z

This extends the SH DMA API for allowing handling of DMA channels based off of their respective capabilities. A couple of functions are added to the existing API, the core bits are register_chan_caps() for registering channel capabilities, and request_dma_bycap() for fetching a channel dynamically based off of a capability set.

sh: Drop name overload in dma-sh.

2006-12-06T01:45:39Z

Pass along the dev_id from request_dma() all the way down, rather than inserting an artificial name relating to the TEI line that we were doing before. This makes the line a bit less obvious, but dev_id is the proper behaviour for this regardless. Signed-off-by: Paul Mundt

sh: Make dma-isa depend on ISA_DMA_API.

2006-12-06T01:45:39Z

Previously we linked in the ISA DMA wrapper unconditionally. As there are very few users of this, it's better to make it conditional. Signed-off-by: Paul Mundt
