2006-12-01[ARM] 3965/1: ixp2000: fix handling of pci master abortsLennert Buytenhek
The master abort check in ixp2000_pci_read_config() recently started failing due to the compiler optimising out the read access following the clearing of pci_master_aborts. Mark pci_master_aborts volatile to force the compiler to reload it on every use. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-11-01[ARM] 3064/1: start using ixp2000_reg_wrbLennert Buytenhek
Patch from Lennert Buytenhek Switch the users of ixp2000_reg_write that depend on writes being flushed out of the write buffer by the time that function returns over to ixp2000_reg_wrb. When using XCB=101, writes to the same functional unit are still guaranteed to complete in order, so we only need to protect against: - reordering of writes to different functional units - masking an interrupt and then reenabling the IRQ bit in CPSR Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Deepak Saxena <dsaxena@plexity.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-09-29[ARM] Don't include mach-types.h unnecessarilyRussell King
It's pointless to include mach-types.h if you're not going to use anything from it. These references were removed as a result of: grep -lr 'asm/mach-types\.h' . | xargs grep -L 'machine_is_\|MACH_TYPE_\|MACHINE_START\|machine_type' Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-06-25[PATCH] ARM: 2752/1: disable ixp2000 PCI I/O software workaround on chips ↵Lennert Buytenhek
that don't need it Patch from Lennert Buytenhek The later ixp2000 models don't need the PCI I/O workaround that we currently perform. Add a config option to disable the workaround, and panic on boot if a kernel without the workaround is booted on a buggy chip. As only pre-production ixp2000s need the workaround, the default is for it not to be configured in.

2005-04-29[PATCH] ARM: 2659/1: do not assign PCI I/O address zero on IXP2000Lennert Buytenhek
Patch from Lennert Buytenhek Assigning the address zero to a PCI device BAR causes some part of the PCI subsystem to believe that resource allocation for that BAR failed due to resource conflicts, which will make attempts to enable the device fail. Work around this by assigning I/O addresses starting from 00010000. While we're at it, make the PCI I/O resource end at 0001ffff, since we only have 64k of outbound I/O window on the IXP2000, and we don't do bank switching.

2005-04-29[PATCH] ARM: 2658/1: start ixp2000 pci memory resource at 0xe0000000Lennert Buytenhek
Patch from Lennert Buytenhek On the IXDP2800, the bootloader does an awful job of configuring the PCI bus, so we make linux reconfigure everything. Having a 1:1 pci:phys address mapping generally simplifies everything, so try to allocate PCI addresses from the [e0000000..ffffffff] range, which is the physical address range of the outbound PCI window on the IXP2000. This does not affect any of the other IXP2000 platforms since they all use their bootloader's PCI resource assignment.

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!
