2009-06-08[ARM] Kirkwood: create a mapping for the Security Accelerator SRAMNicolas Pitre4-8/+12
Always creating the physical mapping should do no harm, so let's remove the interface that was provided for its optional creation and make the mapping static. Signed-off-by: Nicolas Pitre <nico@marvell.com>
2009-06-08[ARM] Kirkwood: let's use real size for resourcesNicolas Pitre1-3/+1
We don't have to define resources to the minimal physical window size as setup_cpu_win() will cope with smaller sizes already. Signed-off-by: Nicolas Pitre <nico@marvell.com>
2009-06-08[ARM] orion5x: add sram support for cryptoSebastian Andrzej Siewior4-2/+56
The security accelerator which can act as a puppet player for the crypto engine requires its commands in the sram. This patch adds support for the phys mapping and creates a platform device for the actual driver.

2009-06-08[ARM] Orion/Kirkwood: rename orion5x_wdt to orion_wdtNicolas Pitre3-10/+10
The Orion watchdog driver is also used on Kirkwood. Convention is to use orion5x for stuff specific to 88F5xxx Orion chips and simply "orion" for shared stuff across SoCs including Kirkwood. Signed-off-by: Nicolas Pitre <nico@marvell.com>
2009-06-08[ARM] Kirkwood: Add the watchdog timer as a platform device.Thomas Reitmayr2-0/+28

The name of the define for the Reset-Out-Mask register as well as its bit for the watchdog reset are changed to match the names used for Kirkwood (which in turn match the processor specification more closely). There is no functional change. This patch prepares for adding orion5x_wdt as a platform device to Kirkwood.

2009-06-08[ARM] orion: make sure sched_clock() usage of cnt32_to_63() is safeNicolas Pitre1-12/+32
With a TCLK = 200MHz, the half period of the hardware timer is roughly 10 seconds. Because cnt32_to_63() must be called at least once per half period of the base hardware counter, it is a bit risky to rely solely on scheduling to generate frequent enough calls. Let's use a kernel timer to ensure this. Signed-off-by: Nicolas Pitre <nico@marvell.com>

You're right - I got the IOMUX tables wrong and thought UART0 pins are selected unconditionally. But as it turns out TXD1/RXD1 is for UART0 (mxc_uart_device0), TXD2/RXD2 for UART1 (mxc_uart_device1) etc. Below is a new patch.

2009-05-29x86: ignore VM_LOCKED when determining if hugetlb-backed page tables can be ↵Mel Gorman1-1/+5
shared or not Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13302 On x86 and x86-64, it is possible that page tables are shared beween shared mappings backed by hugetlbfs. As part of this, page_table_shareable() checks a pair of vma->vm_flags and they must match if they are to be shared. All VMA flags are taken into account, including VM_LOCKED. The problem is that VM_LOCKED is cleared on fork(). When a process with a shared memory segment forks() to exec() a helper, there will be shared VMAs with different flags. The impact is that the shared segment is sometimes considered shareable and other times not, depending on what process is checking. What happens is that the segment page tables are being shared but the count is inaccurate depending on the ordering of events. As the page tables are freed with put_page(), bad pmd's are found when some of the children exit. The hugepage counters also get corrupted and the Total and Free count will no longer match even when all the hugepage-backed regions are freed. This requires a reboot of the machine to "fix". This patch addresses the problem by comparing all flags except VM_LOCKED when deciding if pagetables should be shared or not for hugetlbfs-backed mapping.

2009-05-29flat: fix data sections alignmentOskar Schirmer6-8/+0
The flat loader uses an architecture's flat_stack_align() to align the stack but assumes word-alignment is enough for the data sections. However, on the Xtensa S6000 we have registers up to 128bit width which can be used from userspace and therefor need userspace stack and data-section alignment of at least this size. This patch drops flat_stack_align() and uses the same alignment that is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's not defined by the architecture. It also fixes m32r which was obviously kaput, aligning an uninitialized stack entry instead of the stack pointer.

2009-05-28davinci: add SRAM allocatorDavid Brownell4-1/+103
Provide a generic SRAM allocator using genalloc, and vaguely modeled after what AVR32 uses. This builds on top of the static CPU mapping set up in the previous patch, and returns DMA mappings as requested (if possible). Compared to its OMAP cousin, there's no current support for (currently non-existent) DaVinci power management code running in SRAM; and this has ways to deallocate, instead of being allocate-only. The initial user of this should probably be the audio code, because EDMA from DDR is subject to various dropouts on at least DM355 and DM6446 chips.

Package on-chip SRAM. It's always accessible from the ARM, so set up a standardized virtual address mapping into a 128 KiB area that's reserved for platform use. In some cases (dm6467) the physical addresses used for EDMA are not the same as the ones used by the ARM ... so record that info separately in the SOC data, for chips (unlike the OMAP-L137) where SRAM may be used with EDMA. Other blocks of SRAM, such as the ETB buffer or DSP L1/L2 RAM, may be unused/available on some system. They are ignored here.
