* [ARM] Kirkwood: instantiate the orion_spi driver in the platform codeLennert Buytenhek2008-08-093-0/+54

* [ARM] prevent crashing when too much RAM installedLennert Buytenhek2008-08-093-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch will truncate and/or ignore memory banks if their kernel direct mappings would (partially) overlap with the vmalloc area or the mappings between the vmalloc area and the address space top, to prevent crashing during early boot if there happens to be more RAM installed than we are expecting. Since the start of the vmalloc area is not at a fixed address (but the vmalloc end address is, via the per-platform VMALLOC_END define), a default area of 128M is reserved for vmalloc mappings, which can be shrunk or enlarged by passing an appropriate vmalloc= command line option as it is done on x86. On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000, two 512M RAM banks and vmalloc=128M (the default), this patch gives: Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap). Memory: 512MB 352MB = 864MB total On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe800000, two 256M RAM banks and vmalloc=768M, this patch gives: Truncating RAM at 00000000-0fffffff to -0e7fffff (vmalloc region overlap). Ignoring RAM at 10000000-1fffffff (vmalloc region overlap). Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Tested-by: Riku Voipio <riku.voipio@iki.fi>

* [ARM] Orion: export red SATA lights on TS-409, fix SATA presence/activityMartin Michlmayr2008-08-091-0/+42
| | | | | | | | | | | | Export the four red SATA LEDs on the QNAP TS-409 that are connected through gpio. Since the boot loader apparently sets the SATA LEDs 2-4 to red and the SATA LED can only be red or green (but not both), exporting the red SATA LEDs (which automatically turns them off upon boot) makes the green SATA presence/activity indication visible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ideally this could be simplified further such that we could pass the pointer down directly into the xcall_deliver() implementation.

Therefore we can pass a pointer to the mask directly. One of the motivations in this transformation is to make use of "&cpumask_of_cpu(cpu)" which evaluates to a pointer to constant data in the kernel and thus takes up no stack space. Hopefully someone in the future will change the interface of arch_send_call_function_ipi() such that it passes a const cpumask_t pointer so that this will optimize ever further.
