| | | | | | | | | | | | | This patch adds the main functionality for parsing the stack unwinding information generated by the ARM EABI toolchains. The unwinding information consists of an index with a pair of words per function and a table with unwinding instructions.

| | | | | | | | | | | | | | | | | | | | | | | | xm_x2xx_defconfig currently supports 3 platforms: CM-X255, CM-X270 and EM-X270. Although EM-X270 is similar to CM-X2XX, it has a lot of unique features. Keeping these features in the same _defconfig increases the kernel size in the way it does not fit into CM-X2XX NOR flash.

(refer to 76d2160147f43f982dfe881404cfde9fd0a9da21) But if interrupts are not masked, the processor can wake up while in Suspend-to-RAM state by an external interrupt. For example, if an OMAP3 board is connected to Host PC by USB and entered to Suspend-to-RAM state, it wake up automatically by M_IRQ_92. The disable_irq() function can't disable the interrupt in H/W level, So I modified arch/arm/mach-omap2/irq.c Signed-off-by: Kim Kyuwon <chammoru@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

A write to the timer device will be usually posted, but it takes roughly 3 cycles before it is effective. If the timer is reprogrammed before that, the CPU will stall until the previous write completes. This was pointed out by Richard Woodruff. Since the lower bound for min_delta_ns is 1000, the change is visible only with tick rates less than 3 MHz. Also note that the old value is incorrect for 32 kHz also due to a rounding error, and it can cause the timer queue to hang (due to clockevent code trying to program the timer with zero ticks).
