sh: share the correct version of start.S among all cpus

2016-12-03T02:32:53Z

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.

sh: add shared relocate_code() function and call board_init_r()

2016-12-03T02:32:52Z

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.

sh: Fix build errors for generic board

2016-05-27T19:39:51Z

This includes the following fixes: - Define needed __init_end symbol - see initr_reloc_global_data() - Drop SH-specific struct bd_info - Add an empty relocate_code() function This prevents build errors with generic board, but the code will still need work. Perhaps this is a better alternative than deleting the code. Signed-off-by: Simon Glass

remove unnecessary version.h includes

2015-03-24T14:50:50Z

Various files are needlessly rebuilt every time due to the version and build time changing. As version.h is not actually needed, remove the include.

sh: move CONFIG_{SH2, SH2A, SH3, SH4} to Kconfig

2014-11-12T23:47:58Z

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.

sh: unify sh2/sh3/sh4 linker scripts

2014-07-24T03:02:23Z

The linker scripts of sh2/sh3/sh4 are almost the same. The difference among them is essentially only one line. They can be consolidated into a single file, arch/sh/cpu/u-boot.lds by re-writing the diffrent line as follows: KEEP(*/start.o (.text)) Signed-off-by: Masahiro Yamada Cc: Nobuhiro Iwamatsu Signed-off-by: Nobuhiro Iwamatsu

sh: sh4: Remove CONFIG_SH4A definition from source code

2014-01-09T03:47:15Z

SH4 and SH4A are compatible. But some instructions are different from these. In Linux kernel, It is treated as a separate CPU, but for now, I think that there is no need to divide especially in the U-Boot. This removes CONFIG_SH4A definition from source code, SH4A is treated as SH4. And this fix white space. Signed-off-by: Nobuhiro Iwamatsu
