2011-07-28arm/versatile: Add device tree supportGrant Likely5-0/+126
For testing the dt work, define a dt-enabled versatile platform. This patch adds a new versatile platform for when using the device tree. Add platform and amba devices are discovered and registered by parsing the device tree. Clocks and initial io mappings are still configured statically. This patch still depends on some static platform_data for a few devices which is passed via the auxdata structure to of_platform_populate(), but it is a viable starting point until the drivers can get all configuration data out of the device tree.

2011-07-22PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.Ralf Baechle1-1/+1
Aside of the usual motivation for constification, this function has a history of being abused a hook for interrupt and other fixups so I turned this function const ages ago in the MIPS code but it should be done treewide. Due to function pointer passing in varous places a few other functions had to be constified as well.

2011-07-12ARM: convert PCI defines to variablesRob Herring2-4/+3
Convert PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to variables to allow multi-platform builds. This also removes the requirement for a platform to have a mach/hardware.h. The default values for i/o and mem are 0x1000 and 0x01000000, respectively. Per Arnd Bergmann, other values are likely to be incorrect, but this commit does not try to address that issue.

2011-05-20ARM: 6910/1: MTD: physmap: let set_vpp() pass a platform_device instead of a map_infoMarc Zyngier1-1/+1
The set_vpp() method provided by physmap passes a map_info back to the platform code, which has little relevance as far as the platform is concerned (this parameter is completely unused). Instead, pass the platform_device, which can be used in the pismo driver to retrieve some important information in a nicer way, instead of the hack that was in place. The empty set_vpp function in board-at572d940hf_ek.c is left untouched, as the board/SoC is scheduled for removal.

Commit 7c63984b86 (ARM: do not define VMALLOC_END relative to PAGE_OFFSET) changed VMALLOC_END to be an explicit value. Before this, it was relative to PAGE_OFFSET and therefore converted to unsigned long as PAGE_OFFSET is an unsigned long. This introduced the following build warning. Fix this by changing the explicit defines of VMALLOC_END to be unsigned long.

Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in.

2010-10-01ARM: do not define VMALLOC_END relative to PAGE_OFFSETNicolas Pitre1-1/+1
VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may vary depending on the selected user:kernel memory split mode through CONFIG_VMSPLIT_*. In fact, the goal of moving PAGE_OFFSET down is to accommodate more directly addressed RAM by the kernel below the vmalloc area, and having VMALLOC_END move along PAGE_OFFSET is rather against the very reason why PAGE_OFFSET can be moved in the first place.
