2018-09-10arch: types.h: factor out fixed width typedefs to int-ll64.hMasahiro Yamada
All architectures have the same definition for s8/16/32/64 and u8/16/32/64. Factor out the duplicated code into <asm-generic/int-ll64.h>. 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").

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>

2016-09-23Remove arch/${ARCH}/include/asm/errno.hMasahiro Yamada
Unlike Linux, nothing about errno.h is arch-specific in U-Boot. As you see, all of arch/${ARCH}/include/asm/errno.h is just a wrapper of <asm-generic/errno.h>. 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 <asm/errno.h> are gone.

2015-11-09Replace "extern inline" with "static inline"Måns Rullgård
A number of headers define functions as "extern inline" which is causing problems with gcc5. The reason is that starting with version 5.1, gcc defaults to the standard C99 semantics for the inline keyword. Under the traditional GNU inline semantics, an "extern inline" function would never create an external definition, the same as inline *without* extern in C99. In C99, and "extern inline" definition is simply an external definition with an inline hint. In short, the meanings of inline with and without extern are swapped between GNU and C99. The upshot is that all these definitions in header files create an external definition wherever those headers are included, resulting in multiple definition errors at link time. Changing all these functions to "static inline" fixes the problem since this works as desired in all gcc versions. Although the semantics are slightly different (a static inline definition may result in an actual function being emitted), it works as intended in practice. This patch also removes extern prototype declarations for the changed functions where they existed. Signed-off-by: Mans Rullgard <mans@mansr.com>

2014-07-22m68k: define __kernel_size_t as unsinged int againMasahiro Yamada
Commit ddc94378d changed the definition of __kernel_size_t from unsigned int to unsigned long. It is true that it fixed warnings on some crosstools but it increased warnings on the others. The problem is that we cannot see consistency in terms of the typedef of __kernel_size_t on M68K architecture. However, I'd like to suggest to have __kernel_size_t to be unsigned int again. Rationale: [1] Linux Kernel defines __kernel_size_t on M68K as unsigned int. Let's stick to the Linux's way. [2] We want to build boards with popular pre-built toolchains, not the one locally-built by indivisuals. I think m68-linux-gcc which can be downloaded from www.kernel.org is the candidate for our _recommended_ toolchains. With this patch, all the m68k boards can be built without any warnings. Give it a try with the following crosstools: https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/ x86_64-gcc-4.6.3-nolibc_m68k-linux.tar.xz or https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/ x86_64-gcc-4.9.0-nolibc_m68k-linux.tar.xz (The latter is newer.)

2013-03-15Introduce generic link section.h symbol filesSimon Glass
We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
