* ARM: zImage: remove the static qualifier from global data variablesNicolas Pitre2011-05-071-6/+6
| | | | | | | | | | | | | | | To be able to relocate the .bss section at run time independently from the rest of the code, we must make sure that no GOTOFF relocations are used with .bss symbols. This usually means that no global variables can be marked static unless they're also const. Let's remove the static qualifier from current offenders, or turn them into const variables when possible. Next commit will ensure the build fails if one of those is reintroduced due to otherwise enforced coding standards for the kernel.

* ARM: 6484/1: fix compile warning in mm/init.cAnand Gadiyar2010-11-211-1/+1
| | | | | | | | | | | | | | | | | | 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.

* arm: return both physical and virtual addresses from addruartJeremy Kerr2010-10-201-7/+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>.

* ARM: do not define VMALLOC_END relative to PAGE_OFFSETNicolas Pitre2010-10-011-1/+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.

* ARM: 5910/1: ARM: Add tmp register for addruart and loadspTony Lindgren2010-02-121-1/+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. That can be done with: $ sed -i -e "s/addruart,rx|addruart, rx/addruart, rx, tmp/" arch/arm/*/include/*/debug-macro.S Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] pass reboot command line to arch_reset()Russell King2009-03-191-1/+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.

| * [ARM] dma: Use sensible DMA parameters for Acorn driversRussell King2008-12-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The hardware supports transfers up to a page boundary per buffer. Currently, we work around that in the DMA code by splitting each buffer up as we run through the scatterlist. Avoid this by telling the block layers about the hardware restriction. Eventually, this will allow us to phase out the splitting code, but not until the old IDE layer allows us to control the value it gives to blk_queue_segment_boundary().

* [ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre2008-11-281-7/+0
| | | | | | | | | | | | | | | | 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.
