2010-01-11arm: add support for LZO-compressed kernelsAlbin Tonnerre
- changes to ach/arch/boot/Makefile to make it easier to add new compression types - new piggy.lzo.S necessary for lzo compression - changes in arch/arm/boot/compressed/misc.c to allow the use of lzo or gzip, depending on the config - Kconfig support Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Tested-by: Wu Zhangjin <wuzhangjin@gmail.com> Acked-by: "H.

2010-01-07ARM: S3C64XX: Fix possible clock look in EPLL and MPLL clock chainsBen Dooks
There is a possibility of a loop happening in the PLL output clock chain on the S3C64XX series. clk_mpll's parent was set to be clk_mout_mpll, but this is fed from clk_fout_epll (which is also clk_mpll). clk_mpll is meant to be the output from the MPLL, and clk_mout_mpll is a seperate clock derived from the mux of clk_mpll and clk_fin_mpll and thus should be considered a seperate clock. Anything using clk_mpll directly really should not be relying on this being the clock that is eventually routed to a peripheral, so remove the loop and ensure that the clocks accurately represent the clock chain in the device. The clk_mpll is not being used outside of the s3c6400-clock.c code, so this change should not break anything else. Do the same for the EPLL. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2010-01-06davinci: enable ARCH_HAS_HOLES_MEMORYMODEL for DaVinciSekhar Nori
All DaVinci platforms include a DSP or co-processor for audio/video acceleration. While creating memory for the DSP/co-processor, system integrator can end up creating a hole in the memory map of the sort: <kernel memory> <hole (memory for DSP)> <kernel memory> This sort of configuration needs ARCH_HAS_HOLES_MEMORYMODEL enabled. See further details see this discussion on ARM linux mailing list: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg15262.html The patch is boot tested on OMAP-L138, DM6446 and DM355 EVMs Signed-off-by: Sekhar Nori <nsekhar@ti.com> CC: Sriramakrishnan <srk@ti.com> CC: Khasim Syed Mohammed <khasim@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-01-06davinci: da8xx/omap-l1: mark RTC as a wakeup sourceSekhar Nori
On da850, RTC alarm is a wakeup source from deep sleep. Mark it as a wakeup source after the rtc platform device is registered. Without this patch, the rtc-omap driver suspends the RTC during the suspend sequence and hence it cannot wakeup the SoC.

2010-01-06davinci: cp_intc: provide set_wake functionSekhar Nori
There is nothing special to be done for interrupts which can wakeup the device from sleep on CP-INTC, but not having a set_wake implemented prevents use of common drivers which expect this function to be implemented for all wakeup interrupt sources. This patch fixes the issue encountered when using the omap-rtc driver on DA850. On DA850 the RTC alarm interrupt is used to wake up the SoC from deep sleep mode. Without this patch, the disable_irq_wake throws an unbalanced wake disable warning while resuming because the previous enable call fails for lack of set_wake implementation.
