CONFIG_SYS_GENERIC_BOARD: Finish migration

2018-08-16T20:45:02+00:00

While we have long since migrated to CONFIG_SYS_GENERIC_BOARD being
enabled, we had just a few places left that still referenced or defined
it.  Update.

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.

xtensa: Use asm-generic/io.h

2017-10-03T01:52:22+00:00

Convert the xtensa architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As the generic implementations are
suitable for xtensa this is primarily a matter of moving code.

This has only been build-tested, feedback from architecture maintainers
is welcome.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

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.

board_f: Rename initdram() to dram_init()

2017-04-13T13:40:57+00:00

This allows us to use the same DRAM init function on all archs. Add a
dummy function for arc, which does not use DRAM init here.

board_f: Make relocation functions generic

2017-04-05T20:36:57+00:00

This header file is used by three archs. It could be used by all of them
since relocation is a common function. Move it into a generic file.

Remove arch/${ARCH}/include/asm/errno.h

2016-09-23T21:56:18+00:00

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of .  Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.

Now all of include directives for  are gone.
Deprecate .

xtensa: add support for the 'xtfpga' evaluation board

2016-08-15T22:46:40+00:00

The 'xtfpga' board is actually a set of FPGA evaluation boards that
can be configured to run an Xtensa processor.

 - Avnet Xilinx LX60
 - Avnet Xilinx LX110
 - Avnet Xilinx LX200
 - Xilinx ML605
 - Xilinx KC705

These boards share the same components (open-ethernet, ns16550 serial,
lcd display, flash, etc.).
