u-boot.git/include/asm-generic, branch v2018.11

Add include/asm-generic/atomic.h

2018-09-26T01:49:18+00:00

The arm, xtensa and mips version of atomic.h were already very similar
(the mips one was a copy of xtensa). Combine these implementations
together to produce a generic atomic.h that can be included by these
architectures (and any others that need it in future).

arch: types.h: factor out fixed width typedefs to int-ll64.h

2018-09-11T00:48:16+00:00

All architectures have the same definition for s8/16/32/64
and u8/16/32/64.

Factor out the duplicated code into .

BTW, Linux unified the kernel space definition into int-ll64.h
a few years ago as you see in Linux commit 0c79a8e29b5f
("asm/types.h: Remove include/asm-generic/int-l64.h").

u-boot: remove driver lookup loop from env_save()

2018-07-30T11:18:47+00:00

When called with ENVOP_SAVE, env_get_location() only returns the
gd->env_load_location variable without actually checking for
the environment location and priority.

This behaviour causes env_save() to fall into an infinite loop when
the low-level drv->save() call fails.

The env_save() function should not loop through the environment
location list but it should save the environment into the location
stored in gd->env_load_location by the last env_load() call.

fdt: Add device tree memory bindings

2018-07-09T15:11:00+00:00

Support a default memory bank, specified in reg, as well as
board-specific memory banks in subtree board-id nodes.

This allows memory information to be provided in the device tree,
rather than hard-coded in, which will make it simpler to handle
similar devices with different memory banks, as the board-id values
or masks can be used to match devices.

efi_loader: allow unaligned memory access

2018-06-03T13:27:21+00:00

The UEFI spec mandates that unaligned memory access should be enabled if
supported by the CPU architecture.

This patch adds an empty weak function unaligned_access() that can be
overridden by an architecture specific routine.

SPDX: Convert a few files that were missed before

2018-05-11T00:38:35+00:00

As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

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.

powerpc: mpc8xx: Change CONFIG_8xx to CONFIG_MPC8xx

2018-04-06T20:30:37+00:00

CONFIG_8xx doesn't mean much outside of arch/powerpc/
This patch renames it CONFIG_MPC8xx just like CONFIG_MPC85xx etc ...
It also renames 8xx_immap.h to immap_8xx.h to be consistent with
other file names.

env: Fix env_load_location

2018-02-16T16:12:41+00:00

Commit 7d714a24d725 ("env: Support multiple environments") added
static variable env_load_location. When saving environmental
variables, this variable is presumed to have the value set before.
In case the value was set before relocation and U-Boot runs from a
NOR flash, this variable wasn't writable. This causes failure when
saving the environment. To save this location, global data must be
used instead.

efi_loader: fix building crt0 on arm

2018-02-09T23:24:00+00:00

Before the patch an undefined constant EFI_SUBSYSTEM was used in the
crt0 code. The current version of binutils does not swallow the error.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888403

The necessary constant IMAGE_SUBSYSTEM_EFI_APPLICATION is already
defined in pe.h. So let's factor out asm-generic/pe.h for the
image subsystem constants and use it in our assembler code.

IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification
let's use IMAGE_SUBSYSTEM_EFI_ROM instead.

The include pe.h is only used in code maintained by Alex so let him be the
maintainer here too.
