2011-02-17ARM: P2V: avoid initializers and assembly using PHYS_OFFSETRussell King
As PHYS_OFFSET will be becoming a variable, we can't have it used in initializers nor assembly code. Replace those in generic code with a run-time initialization. Replace those in platform code using the individual platform specific PLAT_PHYS_OFFSET.

2011-02-15ARM: Defer lookup of machine_type to setup.cRussell King
Since the debug macros no longer depend on the machine type information, the machine type lookup can be deferred to setup_arch() in setup.c which simplifies the code somewhat. We also move the __error_a functionality into setup.c for displaying a message when a bad machine ID is passed to the kernel via the LL debug code. We also log this into the kernel ring buffer which makes it possible to retrieve the message via a debugger. Original idea from Grant Likely.

2011-01-31ARM: smp_on_up: allow non-ARM SMP processorsRussell King
Allow non-ARM SMP processors to use the SMP_ON_UP feature. CPUs supporting SMP must have the new CPU ID format, so check for this first. Then check for ARM11MPCore, which fails the MPIDR check. Lastly check the MPIDR reports multiprocessing extensions and that the CPU is part of a multiprocessing system.

Ensure that the ISA/PCI IO space accessors are properly ordered on ARMv6+ architectures. These should always be ordered with respect to all other accesses.

2011-01-31ARM: initrd: disable initrd if passed address overlaps reserved regionRussell King
Disable the initrd if the passed address already overlaps the reserved region. This avoids oopses on Netwinders when NeTTrom tells the kernel that an initrd is located at mem+4MB, but this overlaps the BSS, resulting in the kernels in-use BSS being freed. This should be applied to v2.6.37-stable. Cc: <stable@kernel.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-01-26console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn
The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

2011-01-25ARM: 6636/1: ep93xx: default multiplexed gpio ports to gpio modeHartley Sweeten
The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface peripheral.  At power-up they default into non-GPIO mode with the Key Matrix controller enabled so these ports are unusable for GPIO.  Note that the Keypad Interface peripheral is only available in the EP9307, EP9312, and EP9315 processor variants. The keypad support will clear the DeviceConfig bits appropriately to enable the Keypad Interface when the driver is loaded.  And, when the driver is unloaded it will set the bits to return the ports to GPIO mode. To make these ports available for GPIO after power-up on all EP93xx processor variants, set the KEYS and GONK bits in the DeviceConfig register. Similarly, the E, G, and H ports are multiplexed with the IDE Interface peripheral.  At power-up these also default into non-GPIO mode.  Note that the IDE peripheral is only available in the EP9312 and EP9315 processor variants. Since an IDE driver is not even available in mainline, set the EONIDE, GONIDE, and HONIDE bits in the DeviceConfig register so that these ports will be available for GPIO use after power-up.

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: 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.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

2011-01-18OMAP4: clockdomain: bypass unimplemented wake-up dependency functions on OMAP4Paul Walmsley
Commit 56a6a19dffda6b75cef8d4183c7c6ff650025cbd ("omap2plus: prm: Trvial build break fix for undefined reference to 'omap2_prm_read_mod_reg'") generates a lot of warnings on boot since clockdomain functions that manipulate wake-up dependencies are not implemented yet on OMAP4 for 2.6.38. This patch bypasses the OMAP2/3 functions on OMAP4, which in turn avoids the warnings when the functions would attempt to call the underlying OMAP2/3 PRCM functions. A one-line warning is still logged from the clockdomain code that the OMAP4 wake-up dependency code is not yet implemented. A clockdomain wake-up and sleep dependency implementation for OMAP4 from Rajendra should be possible to merge during the 2.6.39 merge window: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg41748.html http://www.mail-archive.com/linux-omap@vger.kernel.org/msg42222.html Reported-by: Russell King <rmk+kernel@arm.linux.org.uk> Cc: Rajendra Nayak <rnayak@ti.com> Cc: Benoît Cousson <b-cousson@ti.com> Cc: Santosh Shilimkar <santosh.shilimkar@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2011-01-18OMAP: counter_32k: init clocksource as part of machine timer initPaul Walmsley
After commit dc548fbbd2ecd0fc3b02301d551e5f8e19ae58fd ("ARM: omap: convert sched_clock() to use new infrastructure"), OMAPs that use the 32KiHz "synchronization timer" as their clocksource crash during boot: [ 0.000000] OMAP clockevent source: GPTIMER1 at 32768 Hz [ 0.000000] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 0.000000] pgd = c0004000 [ 0.000000] [00000000] *pgd=00000000 [ 0.000000] Internal error: Oops: 80000005 [#1] SMP [ 0.000000] last sysfs file: [ 0.000000] Modules linked in: [ 0.000000] CPU: 0 Tainted: G W (2.6.37-07734-g2467802 #7) [ 0.000000] PC is at 0x0 [ 0.000000] LR is at sched_clock_poll+0x2c/0x3c [ 0.000000] pc : [<00000000>] lr : [<c0060b74>] psr: 600001d3 [ 0.000000] sp : c058bfd0 ip : c058a000 fp : 00000000 [ 0.000000] r10: 00000000 r9 : 411fc092 r8 : 800330c8 [ 0.000000] r7 : c05a08e0 r6 : c0034c48 r5 : c05ffc40 r4 : c0034c4c [ 0.000000] r3 : c05ffe6c r2 : c05a0bc0 r1 : c059f098 r0 : 00000000 [ 0.000000] Flags: nZCv IRQs off FIQs off Mode SVC_32 ISA ARM Segment kernel [ 0.000000] Control: 10c53c7f Table: 8000404a DAC: 00000017 This is due to the recent ARM init_sched_clock() changes and the late initialization of the counter_32k clock source.
