Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

ARM: 6058/1: Add support for PCI domains This patch adds support for PCI domains on ARM platforms. Also, protect asm/mach/pci.h from multiple inclustions, otherwise build fails because of pci_domain_nr() and pci_proc_domain() redefinitions.

ARM: convert PCI defines to variables 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.

[ARM] Fix PCI_DMA_BUS_IS_PHYS for ARM PCI_DMA_BUS_IS_PHYS was defined to be zero, which meant we ignored the DMA mask for IDE and SCSI transfers. This is wrong - we have no DMA translation hardware. We want to obey DMA masks so that the block layer performs bouncing itself. Reported-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
