sh: sh3: Remove CPU support

2019-05-10T20:43:18Z

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. Signed-off-by: Marek Vasut Cc: Chris Brandt Cc: Nobuhiro Iwamatsu Cc: Vladimir Zapolskiy Cc: Yoshihiro Shimoda

sh: tmu: Zap get_tbclk and timer_read_counter

2018-09-15T01:19:07Z

Replace those two functions with generic ones by defining the timer macros in include/config/*.h . Signed-off-by: Marek Vasut

sh: tmu: Clean up register usage

2018-09-15T01:19:07Z

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

sh: tmu: Inline sh_tmu.h

2018-09-15T01:19:07Z

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

sh: tmu: Clean up CONFIG_SH_TMU_CLK_FREQ

2018-09-15T01:19:07Z

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

sh: tmu: Inline get_tmu0_clk_rate()

2018-09-15T01:19:07Z

This function just returns CONFIG_SH_TMU_CLK_FREQ, use the constant directly instead. Signed-off-by: Marek Vasut

sh: tmu: Inline tmu_timer_{start,stop}()

2018-09-15T01:19:07Z

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

sh: tmu: Simplify the tmu_bit math

2018-09-15T01:19:07Z

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

sh: tmu: Clean up CONFIG_SYS_TMU_CLK_DIV

2018-09-15T01:19:07Z

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

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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
