* arch/sh/drivers/dma/dma-sh.c: Correct use of ! and &Julia Lawall2008-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: fix pci io access for r2d boardsMagnus Damm2008-02-14
| | | | | | | | | | | | Use generic_io_base to point out the pci io window, and make sure the highest port address used is SH7751_PCI_IO_SIZE - 1. This patch fixes pci io port access for the r2d boards - CONFIG_8139TOO_PIO now works as expected. So does the alsa driver for CMI8738.

* sh: update r7780rp interrupt codeMagnus Damm2008-01-28
| | | | | | | | | | | | | | | | | | This patch updates the board specific irq code for r7780rp. The new code is very similar to the other highlander implementations, with the exception that the r7780rp handles pci interrupts using IRL. To simplify the pci code and use the same interrupt numbers as r7780mp and r7785rp we hook in to the cpu specific pci vectors. The pci interrupts and the push switch all work well with and without this patch. CF and AX88796 are not ok though and the source of the problem is unknown at this point. The AX88796 does for not detect it's proper mac address (IPL gets it right) and the kernel hangs on CF access. As a workaround this patch removes the CF and the AX88796 from the platform datain case of r7780rp. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* Remove dma_cache_(wback|inv|wback_inv) functionsRalf Baechle2007-10-17
| | | | | | | | | | | | | | | | | | | | dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized cache managment API for I/O purposes. Originally it was basically the raw MIPS low level cache API exported to the entire world. The API has suffered from a lack of documentation, was not very widely used unlike it's more modern brothers and can easily be replaced by dma_cache_sync. So remove it rsp. turn the surviving bits back into an arch private API, as discussed on linux-arch.

* sh: intc - convert board specific r2d codeMagnus Damm2007-09-20
| | | | | | | | | | | | | | | | | | | | | This patch converts the board specific interrupt code for r2d to make use of intc. While at it we improve the Kconfig to avoid confusion. - Two sets of interrupt tables exist - one for R2D-1 and one for R2D-PLUS. - R2D-1 and R2D-PLUS use the same irq constants. - R2D-1 has AX88796 support, R2D-PLUS does not hook up that IRQ. - R2D-PLUS has KEY support, R2D-1 does not hook up that IRQ. - The number and order of IRQ values are disconnected from register bits. - Interrupt sources now start from IRQ 100. - The machvec demux function converts from irlm IRQ 0-14 to IRQ 100++. Tested on R2D-1 and R2D-PLUS boards. Version 2 adds CONFIG_RTS7751R2D_1 and CONFIG_RTS7751R2D_PLUS together with intc structured as __initdata.

* sh: Fix Dreamcast DMA issues.Adrian McMenamin2007-07-24
| | | | | | | | | | | | | The current SH DMA API is somewhat broken, not correctly matching virtual channel to the correct SH DMAC. This wasn't noticeable when using g2 DMA for the sound driver - one channel 0 is as good as any other! - but caused the pvr2 driver to fail. This patch fixes the pvr2 problem and consequently fixes the sound driver to ensure it continues to function.

| | | | | | | | | | | | | | | | | | | | | This patch updates the r2d board support in a few ways: - CPU_SUBTYPE_SH7751R is selected in the defconfig to play well with the r2d board Kconfig entry. Without this the defconfig results in no board enabled. - Enable EARLY_PRINTK. - Enable SH_STANDARD_BIOS - this works well for early printk on the r2d board. - Add "earlyprink=bios" to the cmdline for early serial port output by default. - CONFIG_SUBTYPE_SH7751R support is added to the sh-specific pci makefile.

| | | | | | | | | | | | | | The DMABRG is a special DMA unit within the SH7760 which does data transfers from main memory to Audio units and USB shared memory. It has 3 IRQ lines which generate 10 events, which have to be masked unmasked and acked in a single 32bit register. It works independently from the tradition SH DMAC, but blocks usage of DMAC channel 0. This patch adds 2 functions to associate callbacks with DMABRG events and initialization.

* sh: Fix PCI BAR address-space wraparound.Hideo Saito2007-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
