2008-05-28MX27 Serial: Disable all UARTS but the firstJustin Waters
The Lite kit only uses the first UART. The rest have been scavenged for pins. This disables all UARTS but the first so that there are no more pin conflicts. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-28MXC GPIO: Fix datain reading for MX27Justin Waters
The GPIO pins for the MX27 are read differently than those on the MX31. Rather than reading the Data Register (DR), you must read the Sample Status Register (SSR). Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-23Clean up MX27 CRM Register DefinitionsJustin Waters
The MX27 crm_regs.h file was a complete mess, obviously hastily ported from the MX31 version, which was also a mess. I cleaned it up quite a bit, although more work still needs to be done such as fixing the naming conventions. This is build tested on the MX27 Lite Kit. It may break MX27 builds. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-23MX27 DPTC: Remove Vestigal CodeJustin Waters
The Dynamic Processor Temperature Control Module is significantly different on the MX27 as compared to the MX31. It seems that some MX31 code slipped into the MX27 devices file, but essentially did nothing except try to register a device that didn't have a driver. I removed this code. I also fixed an issue with the Kconfig where you could select the DPTC module without the power management chip enabled, which causes a compilation error.

2008-05-21MX27LITE: Miscellaneous code cleanupJustin Waters
There were a lot of carryovers from the MX27 ADS code that were either useless or just plain wrong. This commit gets rid of these issues. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-21MX27LITE: Modify GPIO pins for SDHC2Justin Waters
The SDHC2 uses GPIO pins for WP and CD signals. This patch assigns these pins to that interface. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-21MX27: Add ability to enable individual Secure Digital controllersJustin Waters
Enabling the SD interface on the MX27 chip will enable all of the interfaces. Since we only use one of them, we should be able to flip them on and off individually. Ultimately, we'd like to do this is the board-specific file, but that will require additional work. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-20MX27LITE_GPIO: Fix pins for USBOTG interfaceJustin Waters
The USBOTG interface uses two GPIO pins for its PWR_EN and OC signals. These pins are associated with the OTG interface and the PWR_EN is cleared since the power enable signal for the power controller is low-true. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-20Update pin configuration for USB Host 2 on the Lite Kit.Justin Waters
The USB Host 2 on the MX27 Litekit uses the USB_POWER and USB_OC_B pins for power and overcurrent detect, respectively. In order to make them function properly, we need to assign those pins to the Host 2 driver and change the H2PM field of the USB_CTRL register on the i.MX27. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-20MX27LITE_GPIO: Fix GPIO conflicts between USB Host 2 and SPI 1Justin Waters
USB Host 2 and SPI 1 only conflict with one pin. If the SPI bus is not using the slave select 2 (SS2) pin (which the Atlas chip does not), then you can use both the SPI 1 and USB Host 2 interfaces simultaneously. This patch disables the MSB of the slave select if Host 2 is enabled. This will limit SPI1 to only 4 slaves instead of 8. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-16MX27Litekit: Update NOR Flash partition tableJustin Waters
The NOR flash on the Litekit is significantly smaller than that on the ADS board. This breaks the partitions into three blocks: one for LogicLoader, one for the LogicLoader configuration data, and one for miscellaneous use. Signed-off-by: Justin Waters <justin.waters@timesys.com>
2008-05-14Backport mach-types to include mx27litekitJustin Waters
The mach-type for the i.MX27 litekit is not in 2.6.24. This is a backport from another version of the kernel. It was provided to us by LogicPD. Signed-off-by: John Scherzer <john.scherzer@timesys.com> Acked-by: Justin Waters <justin.waters@timesys.com>
2008-05-14i.MX27 Litekit board supportJustin Waters
The i.MX27 Litekit is based off of Freescale's i.MX27 processor. This patch adds the basic board support files and memory map information for this board. Signed-off-by: John Scherzer <john.scherzer@timesys.com> Acked-by: Justin Waters <justin.waters@timesys.com>

2008-01-15Fix ARM profiling/instrumentation configurationLinus Torvalds
Commit 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 ("Combine instrumentation menus in kernel/Kconfig.instrumentation") broke ARM profiling support, since ARM has some extra Kconfig options and doesn't just use the common OPROFILE/KPROBES config options. Rather than just revert the thing outright, or add ARM-specific knowledge to the generic Kconfig.instrumentation file (where the only and whole point was to be generic, not too architecture-specific), this just makes ARM not use the generic version, since it doesn't suit it. So create an arm-specific version of Kconfig.instrumentation instead, and use that.

2008-01-10[ARM] vfp: fix fuitod/fsitod instructionsRussell King

2007-11-26[ARM] 4659/1: remove possibilities for spurious false negative with ↵Nicolas Pitre
__kuser_cmpxchg The ARM __kuser_cmpxchg routine is meant to implement an atomic cmpxchg in user space. It however can produce spurious false negative if a processor exception occurs in the middle of the operation. Normally this is not a problem since cmpxchg is typically called in a loop until it succeeds to implement an atomic increment for example. Some use cases which don't involve a loop require that the operation be 100% reliable though. This patch changes the implementation so to reattempt the operation after an exception has occurred in the critical section rather than abort it. Here's a simple program to test the fix (don't use CONFIG_NO_HZ in your kernel as this depends on a sufficiently high interrupt rate): #include <stdio.h> typedef int (__kernel_cmpxchg_t)(int oldval, int newval, int *ptr); #define __kernel_cmpxchg (*(__kernel_cmpxchg_t *)0xffff0fc0) int main() { int i, x = 0; for (i = 0; i < 100000000; i++) { int v = x; if (__kernel_cmpxchg(v, v+1, &x)) printf("failed at %d: %d vs %d\n", i, v, x); } printf("done with %d vs %d\n", i, x); return 0; } Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
