2008-10-21[ARM] S3C: Fix PWM build on S3C6400Ben Dooks
The pwm-clock.c needs <mach/map.h> which is included via other means on S3C24XX systems, so ensure it is explicitly included. Remove the includes of regs-clock.h and regs-gpio.h as these are not needed by the build. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-10-21[ARM] S3C64XX: Initial arch header filesBen Dooks
Add the initial header files for the S3C64XX support to satisfy the minimal requirements to build a kernel. Some definitions will therefore be placeholders or empty functions that will ensure that the system can build and have base functionality. These will be filled in at a later date. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-10-21[ARM] S3C24XX: Change clock locking to use spinlocks.Ben Dooks
We cannot sleep if we have cpufreq pm enabled during some of the clock operations, so change to use a spinlock to protect the clock system. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] CPUFREQ: S3C24XX serial CPU frequency scaling support.Ben Dooks
Add support for CPU frequency scalling to the S3C24XX serial driver. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24XX: Split timer pending code outBen Dooks
Split the timer pending code out to a seperate per-machine header so that when compiling for mach-s3c2410 or mach-s3c24a0 we can use the right timer code without having to #ifdef the timer driver. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24XX: Split pll code out of regs-clock.hBen Dooks
Move the PLL calculation code into it's own header file for re-use with the other plat-s3c24xx based systems such as the S3C24A0. Note, we change the name of s3c2410_get_pll to the more generically named s3c24xx_get_pll as well as the related defintions. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24XX: Split DCLK/CLKOUT definitions out of clock.cBen Dooks
Only certain boards need these clocks, and they are not available on some CPUs (such as the S3C24A0) so remove them from arch/arm/plat-s3c24xx/clock.c and into their own file with appropriate Kconfig entries. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24A0: Initial architecture support filesBen Dooks
Initial architecture support for the S3C24A0 ARCH_S3C24A0. We don't yet add an kconfig entry in the main arch/arm/Kconfig file as the series is not complete, so that is left until enough support is in to be useful. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24XX: Move initialisation code to arch/arm/plat-s3cBen Dooks
We need to add plat-s3c to the build to get the headers that will go in here once moved from include/asm-arm so we may as well put some useful common s3c code in here to stop the errors generated form having nothing built. The cpu setup is now passed the cpu idcode and the table of supported cpus to s3c_init_cpu() to abstract the cpu identification out of the initial io setup. As well as moving the cpu initialisation code, we move the map of the board specific items up to the calling code as none of the map_io() functions actually do anything other than pass this to iotable_init(). This patch does not rename any of the init functions that will be common to s3c24xx and any other s3c architectures as this can be done at a later date as it will touch all the board support files which use functions such as s3c24xx_init_clocks() and s3c24xx_init_uarts(). Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h still has functions that are used by both the cpu and board initialisation functions. This means that each board has definitions specific to the cpu support included and the vice-versa. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24A0: Serial port definitions and driver support.Sandeep Patil
Add serial support for S3C24A0, based on current S3C2410 UART driver. It adds necessary new defines in regs-serial.h for S3C24A0 and the code to support this device in drivers/serial/s3c24a0.c Signed-off-by: Sandeep Patil <sandeep.patil@azingo.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24XX: Add default <mach/io.h> headerBen Dooks
Add a default header for <mach/io.h> for systems such as the S3C24A0 which do not need any of the complex code that the S3C2410 uses. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24XX: Move vmalloc.h to plat-s3cBen Dooks
vmalloc.h is common across all the current s3c platforms, so move it to arch/arm/plat-s3c/include/mach to be used for all the targets. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C: Make <mach/timex.h> commonBen Dooks
Move <mach/timex.h> to arch/arm/plat-s3c/include/mach/timex.h so it can be the default for all S3C based architectures. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24XX: Split map.h into plat-s3c24xx and mach-s3c2410Ben Dooks
Split the map.h definitions into common S3C24XX code by adding arch/arm/plat-s3c24xx/include/plat/map.h and altering the machine specific header for the S3C24A0. As we add a new <plat/map.h> we move the original one in arch/arm/plat-s3c include directory to be called map-base.h to distinguish the two files. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24A0: Debug macro definitionsBen Dooks
Add the necessary debug macros for the S3C24A0 to enable kernel debugging, and fix a bug with selecting the wrong default debug implementation from the base include. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24A0: Correct S3C2410_PA_GPIO in S3C24XX_VA_GPIOSandeep Patil
The definition of S3C24XX_VA_GPIO used S3C2410_PA_GPIO where it should have read S3C24XX_PA_GPIO. Signed-off-by: Sandeep Patil <sandeep.patil@azingo.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-10-21[ARM] S3C24A0: arch/arm/mach-s3c24a0/include/mach header filesSandeep Patil

2008-10-21[ARM] S3C2410: Move base clock code to plat-s3c24xxBen Dooks

2008-10-20binfmt_elf_fdpic: Update for cputime changes.Paul Mundt
Commit f06febc96ba8e0af80bcc3eaec0a109e88275fac ("timers: fix itimer/ many thread hang") introduced a new task_cputime interface and subsequently only converted binfmt_elf over to it. This results in the build for binfmt_elf_fdpic blowing up given that p->signal->{u,s}time have disappeared from underneath us. Apply the same trivial fix from binfmt_elf to binfmt_elf_fdpic.

2008-10-20Export tiny shmem_file_setup for DRM-GEMHugh Dickins
We're trying to keep the !CONFIG_SHMEM tiny-shmem.c (using ramfs without swap) in synch with CONFIG_SHMEM shmem.c (and mpm is preparing patches to combine them). I was glad to see EXPORT_SYMBOL_GPL(shmem_file_setup) go into shmem.c, but why not support DRM-GEM when !CONFIG_SHMEM too? But caution says still depend on MMU, since !CONFIG_MMU is.. different.
