Move this uncommon header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-05-10sh: sh3: Remove CPU supportMarek Vasut
This CPU core is old, no boards using the CPU are left in mainline, it has no prospects of ever being converted to DM, drop it.

2018-09-15sh: tmu: Zap get_tbclk and timer_read_counterMarek Vasut
Replace those two functions with generic ones by defining the timer macros in include/config/*.h . Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-09-15sh: tmu: Clean up register usageMarek Vasut
The code uses all in all three TMU registers, drop the massive register layout structures and just define the required timer registers and use them throughout the code. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-09-15sh: tmu: Inline sh_tmu.hMarek Vasut
The header contains only the TMU register layout, just inline it into the TMU timer implementation and drop the header completely. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-09-15sh: tmu: Clean up CONFIG_SH_TMU_CLK_FREQMarek Vasut
The R-Car Gen2 feeds the TMU with CONFIG_SYS_CLK_FREQ / 2, while the old SH parts use CONFIG_SYS_CLK_FREQ directly. Just put this into the TMU implementation and drop the CONFIG_SH_TMU_CLK_FREQ config option. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-09-15sh: tmu: Inline get_tmu0_clk_rate()Marek Vasut
This function just returns CONFIG_SH_TMU_CLK_FREQ, use the constant directly instead. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-09-15sh: tmu: Inline tmu_timer_{start,stop}()Marek Vasut
These functions are always called for timer = 0, so drop the timer check. Since these functions are called from one place only and they are reduced to one line of code, just inline them. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-09-15sh: tmu: Simplify the tmu_bit mathMarek Vasut
The tmu_bit value evaluates to (ffs(4) >> 1) - 1 = (3 >> 1) - 1 = 0. Just drop the tmu_bit completely as well as CONFIG_SYS_TMU_CLK_DIV. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-09-15sh: tmu: Clean up CONFIG_SYS_TMU_CLK_DIVMarek Vasut
This constant is always 4 , for all boards that exist. Define it once in arch/sh/lib/time.c and remove it from the configs. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2013-11-04sh: convert to common timer codeRob Herring
Convert sh to use the commmon timer code. Remove reset_timer and set_timer as they are unused on sh. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2013-10-17sh: timer: Remove static global variableNobuhiro Iwamatsu
"static u16 bit" is not necessary to use this as static global variable. This patch fixes this. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2013-10-17sh: timer: Mask bit of timer prescalerNobuhiro Iwamatsu
timer_init function sets timer prescaler bit. The previous code so did not mask this bit, this function was to overwrite the bit. This will fix this problem. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

2012-08-21sh: tmu: Removed arch/sh/include/asm/clk.hNobuhiro Iwamatsu
asm/clk.h was included get_peripheral_clk_rate function. But this is not used from anywhere. This removed asm/clk.h, and deleted include line from arch/sh/lib/time.c Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2012-08-21sh: tmu: Changed switch statement to shift operationNobuhiro Iwamatsu
Calculation of the bit position using switch statement can substitute shift operation using ffs. And removed unsed macro and variable. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2012-08-21sh: tmu: Changed TMU driver using array of structuresNobuhiro Iwamatsu
This changed into access using array of structure from access to the register using the definition of the register by macro. And removed white space. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

2010-04-13Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
