2010-10-20arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre7-14/+0
Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>
2010-10-20arm: return both physical and virtual addresses from addruartJeremy Kerr1-7/+5
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. Updated with fixes for OMAP from Jason Wang <jason77.wang@gmail.com> and Tony Lindgren <tony@atomide.com>, and fix for versatile express from Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>.

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.

2010-02-12ARM: 5910/1: ARM: Add tmp register for addruart and loadspTony Lindgren1-1/+1
Otherwise more complicated uart configuration won't be possible. We can use r1 for tmp register for both head.S and debug.S. NOTE: This patch depends on another patch to add the the tmp register into all debug-macro.S files.

2009-03-19[ARM] pass reboot command line to arch_reset()Russell King1-1/+1
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.

2008-11-30[ARM] Add a common typesafe __io implementationRussell King1-2/+2

2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King1-19/+0
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] clps711x: avoid polluting the kernel's namespaceRussell King1-2/+0

2008-11-28[ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre1-19/+1
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.

Move the xtime write mode seqlock into timer_tick(), so it only surrounds the call to do_timer(). This avoids a deadlock in update_process_times() ... hrtimer_get_softirq_time() which tries to get a read mode seqlock on xtime, thereby preventing booting.

2005-04-16Linux-2.6.12-rc2Linus Torvalds17-0/+1042
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!
