2011-02-19ARM: integrator: switch Integrator platforms to use consolidated CLCDRussell King
This switches integrator platforms to use the consolidated CLCD panel support, including the display capabilities. These capabilities prevent the unsupported BGR565 mode being selected, while still allowing RGB5551, BGR5551 and RGB565 modes.

2011-02-19ARM: add versatile family consolidated CLCD supportRussell King
This consolidates the CLCD panel definitions and memory allocation into one location. Rename the Sanyo 2.5in and Epson 2.2in displays after their respective part numbers. Rather than using a general "Sanyo 2.5in" and "Epson 2.2in" description of the display panel, use the manufacturers part number to be more specific. This helps people identify what the timings actually refer to, which are panel specific. While here, add CLCD capability information to each panel definition, which has no effect until we add the board-level capabilities.

2011-02-19ARM: integrator: support CLCD RGB5551 layout for 16bppRussell King
When the CLCD is in anything but RGB888 mode, its outputs are configured for RGB5551 output. Integrator/CP supports RGB565 via an external multiplexer, which we configure for RGB5551 or RGB565 based only on the bits per pixel. So when userspace asks for the RGB555 layout, the mux remains in RGB565 mode, and we produce incorrect colours. Fix this. Note that Integrator doesn't support BGR565 mode, but does support BGR5551.

2011-01-25ARM: 6635/2: Configure reference clock for Versatile Express timersPawel Moll
Timers on Versatile Express mainboard are used as system clock/event sources. Driver assumes that they are clocked with 1MHz signal. Old V2M firmware apparently configured it by default, but on newer boards one can observe that "sleep 1" command takes over 30 seconds to finish, as the timers are fed with 32kHz instead... This patch performs required magic and also removes code clearing timer's control registers, as exactly the same operations are performed by the timer driver few jiffies later.

2011-01-25ARM: versatile: name configuration options after actual board namesRussell King

2011-01-25ARM: realview: name configuration options after actual board namesRussell King
As no one seems to really know which configuration options tie up with which boards, I thought I'd do some investigation and try to work it out. After discussion with some folk in linaro, I think I have this nailed. The names are updated to use the name on the front of the appropriate board user guide for the various baseboards, which I've taken to be the official name for each board. I haven't significantly updated the descriptions for the tiles as that is even less clear - as far as I can see on ARMs website, there is no Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S, ARM1176TZF-S and Cortex-R4F. So exactly what this 'Multicore Cortex-A9 Tile' is... Acked-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-01-21xen: p2m: correctly initialize partial p2m leafStefan Bader
After changing the p2m mapping to a tree by commit 58e05027b530ff081ecea68e38de8d59db8f87e0 xen: convert p2m to a 3 level tree and trying to boot a DomU with 615MB of memory, the following crash was observed in the dump: kernel direct mapping tables up to 26f00000 @ 1ec4000-1fff000 BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<c0107397>] xen_set_pte+0x27/0x60 *pdpt = 0000000000000000 *pde = 0000000000000000 Adding further debug statements showed that when trying to set up pfn=0x26700 the returned mapping was invalid. pfn=0x266ff calling set_pte(0xc1fe77f8, 0x6b3003) pfn=0x26700 calling set_pte(0xc1fe7800, 0x3) Although the last_pfn obtained from the startup info is 0x26700, which should in turn not be hit, the additional 8MB which are added as extra memory normally seem to be ok. This lead to looking into the initial p2m tree construction, which uses the smaller value and assuming that there is other code handling the extra memory. When the p2m tree is set up, the leaves are directly pointed to the array which the domain builder set up. But if the mapping is not on a boundary that fits into one p2m page, this will result in the last leaf being only partially valid. And as the invalid entries are not initialized in that case, things go badly wrong. I am trying to fix that by checking whether the current leaf is a complete map and if not, allocate a completely new page and copy only the valid pointers there. This may not be the most efficient or elegant solution, but at least it seems to allow me booting DomUs with memory assignments all over the range.
