* sh: pass through ioremap() for non-mmu processors.Magnus Damm2009-04-29
| | | | | | | | | | | | | | All 32-bit SuperH processors currently go through __ioremap_mode() and check for IO_TRAPPED and directly mapped segments. With this patch we simplify the MMU less case with a pass through version of __ioremap_mode() which just returns the physical address. The effects of this is change are: - fix non-MMU ioremap() of high address hardware blocks (sh7203 CMT) - make sure IO_TRAPPED is not selected Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: register the rtc-generic platform device properly.Paul Mundt2009-04-28
| | | | | | | | The device registration was accidentally omitted, add it back in. Do some basic device probing as well, so this doesn't show up for platforms that tie in to the RTC interface properly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: setup timers in late_time_init()Magnus Damm2009-04-28
| | | | | | | | | | | | | | This patch moves the SuperH timer setup code from time_init() to late_time_init(). Good things about this change: - interrupts: they are enabled at late_time_init() - mm: regular kmalloc() can be used at late_time_init() Together with moving to late_time_init() this patch changes the sh_cmt driver to always allocate with kmalloc(). This simplifies the code a bit and also fixes section mismatches. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* clocksource: improve sh_cmt clocksource overflow handlingMagnus Damm2009-04-28
| | | | | | | | | | | | This patch improves the sh_cmt clocksource handling. Currently the counter value is ignored in the case of overflow. With this patch the overflow flag is read before and after reading the counter, removing any counter value and overflow flag mismatch issues.

* sh: mach-r2d: add physmap-flash support for R2D+ boards.Jean-Christophe PLAGNIOL-VILLARD2009-04-27
| | | | | | | | | | | The RTS7751R2D_1 boards only support 1MB of socket-mounted MBM29F040 flash, which we just leave alone as it's not terribly interesting. This adds support for the s29gl256p on the r2d+ boards that makes a bit more sense to expose to the user.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The se7751 was still doing the PCI fixups in its own board directory, so we move it over to arch/sh/drivers/pci/ with the rest of the board fixups. It has bitrotted significantly over the years, so will still likely need a bit of work to bring back up to date. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | This follows the similar sort of scheme that the refactored SH7780 code uses, using a 64MB CS3 mapping to handle the window0 case, and simply discarding window1. This vastly simplifies the code, and allows most of the board-specific setup to go die. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the remaining common bits in to pci-lib. Thereby reducing pci.c/pci-new.c to simple bus fixups and controller registration. As more platforms are moved over, the old code will disappear completely and the pci-new bits will be rolled in to pci-lib, eventually replacing pci.c completely.

| | | | | | | | | | | | | | | | | | | | | | | | Now that the io and mem offsets are tracked accordingly, the pci-new version of the bus<->resource mappers can be used generically. This moves them in to pci-lib. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | Not all PCI channels have non-translatable memory windows, this is a special property of the on-chip PCIC with its 0xfd00... mapping, handle this explicitly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This consolidates the pci_iomap() definitions and reworks how the I/O port base is handled. PCI channels can register their own I/O map base, or if none is provided, the system-wide generic I/O base is used instead. Functionally nothing changes, while this allows us to kill off lots of I/O address special casing and lookups. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | * sh: pci: Consolidate pcibios_align_resource() definitions.Paul Mundt2009-04-20
| | | | | | | | | | | | | | | | | | | | | | | | This introduces a saner pcibios_align_resource() that can be used regardless of whether pci-auto or pci-new are being used, and consolidates it in pci-lib.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | This splits off a 'pci-new.c' which is aimed at gradually replacing the pci-auto backend and the arch/sh/drivers/pci/pci.c core respectively. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 68b42d1b548be1840aff7122fdebeb804daf0fa3 ("sh: sh7785lcr: Map whole PCI address space.") changed around the semantics of how various chip-selects are made accessible to PCI. Now that there is a single large mapping covering from CS0-CS6, there is no longer any need to do multi-window mapping. Subsequently, all of the differing implementations can be consolidated in to pci-sh7780. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | The SH7780 PCIC contains a read-only cache line size register that we can derive pci_cache_line_size from. So, make sure that the software idea of the cache line size actually matches the host controller's idea. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | Don't use pci_write_reg() for these, as it defaults to 32-bit. Rather than using the helper, use __raw_writeb() directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reworks how the host controller is probed, and makes it a bit more verbose in the event a new type of controller is detected. Additionally, we also log the revision information. This now uses the proper access sizes for the vendor/device registers, rather than relying on a larger access that encapsulated both of them. Not all devices support 32-bit read cycles for these registers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * sh: pci: Set class/sub-class code correctly for SH7780 PCIC.Paul Mundt2009-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SH7780 PCI host controller implements a configuration header that requires a fair bit of hand-holding to initialize properly. By default it appears as a pre-2.0 host controller given the zeroed out class code, so fix this up properly. Some boards that happened to be using the R7780RP version of the PCIC fixups had set this correctly, but this belongs in the standard initialization, and is by no means board specific.
