2009-08-18iop3xx: ATU and PCI memory configuration correctedAaro Koskinen
There are two 64 MB outbound memory windows at bus addresses 0x80000000..0x83ffffff and 0x84000000..0x87ffffff for PCI memory. Currently, on iop32x, only the lower window is available for allocations, limiting the available space to 64 MB. On iop33x the full 128 MB can be allocated, but the translation value is wrong for the upper window. The patch enables the full 128 MB space on iop32x and corrects the initialization of OMWTVR1. Redundant definitions are deleted. Tested using a Thecus N2100 board with a graphics adapter in the expansion slot. Both windows are in use: 00:05.0 VGA compatible controller: XGI Technology Inc.

2009-03-19[ARM] pass reboot command line to arch_reset()Russell King
OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

2008-11-28[ARM] iop3xx: avoid polluting the kernel's namespaceRussell King
Avoid unnecessarily pollution of the kernel's namespace by avoiding mach/hardware.h in mach/io.h, mach/memory.h and mach/timex.h. Include this header file where necessary. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre
Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.
