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>
2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

2016-12-02sh: share the correct version of start.S among all cpusVladimir Zapolskiy
It is easy to note that SH2/SH3/SH4 start.S code is practically the same with a minor difference for SH2 where a short data header is present. To avoid unwanted code duplication and to automatically convert SH2 and SH3 platforms to generic board support move fixed SH4 start.S into arch/sh/lib/start.S and share it among all platforms.

2016-12-02sh: add shared relocate_code() function and call board_init_r()Vladimir Zapolskiy
Commits b61e90e6fd83 ("sh: Drop the arch-specific board init") and f41e6088eb1a ("sh: Fix build errors for generic board") left code and data relocation done in start.S, however further actual U-boot configuration is not started anymore. Practically SH boards with the code relocated into the expected position by start.S still can be booted, so the change adds this option and provides an option how to relocate code for board_init_r() execution.

2016-12-02sh: add common dram_init() function for all boardsVladimir Zapolskiy
Generic board support assumes a different method of specifying DRAM size on board, also it can be shared among all boards, notably only sh7763rdp board has a custom legacy dram_init(), however the difference is only in printing some additional information, this feature can be removed.

2015-11-19Move console definitions into a new console.h fileSimon Glass

2015-02-25sh: import missing private libraries from Linux 3.19Masahiro Yamada
SuperH is supposed to support the Private Library feature, but it is actually not working. If CONFIG_USE_PRIVATE_LIBGCC is enabled, the build fails for the undefined references to '__sdivsi3_i4i' and '__udivsi3_i4i'. To fix this error, import missing libraries from Linux 3.19 and adjust them for U-Boot: - Remove "#include <linux/module.h>" and "EXPORT_SYMBOL(...)" - Use SPDX-License-Identifier - Remove white space Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

This commit moves CONFIG_SH2, CONFIG_SH2A, CONFIG_SH3, CONFIG_SH4 to Kconfig renaming into CONFIG_CPU_SH2, CONFIG_CPU_SH2A, CONFIG_CPU_SH3, CONFIG_CPU_SH4, respectively because arch/sh/Kconfig of Linux uses CONFIG_CPU_SH* convention.

2014-03-07kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCCMasahiro Yamada
Before this commit, USE_PRIVATE_LIBGCC was defined in arch-specific config.mk and referenced in arch/$(ARCH)/lib/Makefile. We are not happy about parsing config.mk again and again. We have to keep the same behavior with a different way. By adding "CONFIG_" prefix, this macro appears in include/autoconf.mk, include/spl-autoconf.mk. (And treating USE_PRIVATE_LIBGCC as CONFIG macro is reasonable enough.) Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes" in arch/arm/cpu/arm720t/tegra*/config.mk, whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk. It means Tegra enables PRIVATE_LIBGCC only for SPL. We can describe the same behavior by adding #ifdef CONFIG_SPL_BUILD # define CONFIG_USE_PRIVATE_LIBGCC #endif to include/configs/tegra-common.h.

Commit 35fc84fa1ff51e15ecd3e464dac87eb105ffed30 broke bootm on avr32. It requires to call do_bootm_linux() with flag set to BOOTM_STATE_OS_PREP before calling it again with flag set to BOOTM_STATE_OS_GO.
