2010-05-13sh: move sh clock-cpg.c contents to drivers/sh/clk-cpg.cMagnus Damm4-296/+300
Move the CPG helpers to drivers/sh/clk-cpg.c V2. This to allow SH-Mobile ARM to share the code with SH. All functions except the legacy CPG stuff is moved. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-05-13sh: move sh clock.c contents to drivers/sh/clk.Magnus Damm5-536/+561
This patch is V2 of the SH clock framework move from arch/sh/kernel/cpu/clock.c to drivers/sh/clk.c. All code except the following functions are moved: clk_init(), clk_get() and clk_put(). The init function is still kept in clock.c since it depends on the SH-specific machvec implementation. The symbols clk_get() and clk_put() already exist in the common ARM clkdev code, those symbols are left in the SH tree to avoid duplicating them for SH-Mobile ARM.

2010-05-13sh: move sh asm/clock.h contents to linux/sh_clk.h V2Magnus Damm2-146/+152
This patch is V2 of the clock framework move from arch/sh/include/asm/clock.h to include/linux/sh_clk.h and updates the include paths for files that will be shared between SH and SH-Mobile ARM. The file asm/clock.h is still kept in this version, this to depend on as few files as possible at this point. We keep SH specific stuff in there.

2010-05-06sh: Make initrd detection more robust.Paul Mundt1-20/+58
Various boot loaders go to various extents to thwart the initrd detection logic (mostly on account of not being able to be bothered with adhering to the established boot ABI), so we make the detection logic a bit more robust. This makes it possible to work around the SDK7786's firmware's attempts to thwart compressed image booting. Victory is mine. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
