* sh: update r7780rp interrupt codeMagnus Damm2008-01-281-14/+2
| | | | | | | | | | | | | | | | | | 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>
* sh: use declared coherent memory for dreamcast pci ethernet adapterMagnus Damm2008-01-283-72/+11
| | | | | | | | | | | This patch makes the dreamcast use the recently added declared coherent memory functions to point out the memory window suitable for dma. Apart from cleaning up, this gives the dreamcast a proper memory allocator for pci dma memory. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Kill off the remaining ST40 cruft.Paul Mundt2007-11-073-625/+0
| | | | | | | | | | | | | 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.

* Remove dma_cache_(wback|inv|wback_inv) functionsRalf Baechle2007-10-171-1/+1
| | | | | | | | | | | | | | | | | | | | 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 Damm2007-09-211-4/+4
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | 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.

* sh: Fix PCI BAR address-space wraparound.Hideo Saito2007-03-121-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
