sh: sh2: Remove CPU support

2019-05-10T20:43:18+00:00

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.

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

2018-05-07T13:34:12+00:00

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.

sh: Use -m2a-nofpu only

2018-02-21T22:42:47+00:00

Based on reading over the GCC manual, passing both -m2a and -m2a-nofpu
are redundant, as -m2a-nofpu will provide functional code for both.  As
-m2a-nofpu functions with more toolchains and does what is expected,
switch.

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

2016-12-03T02:32:53+00:00

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()

2016-12-03T02:32:52+00:00

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

2016-05-27T19:39:51+00:00

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.

remove unnecessary version.h includes

2015-03-24T14:50:50+00:00

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

2014-11-12T23:47:58+00:00

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

2014-07-24T03:02:23+00:00

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))
