2015-01-14Move container_of() macro to stddef.hStefan Reinauer
It's not a SPI related macro, hence move it to stddef.h where other similar macros live.

2014-09-22Add check_member macro to allow clean and easy struct offset checkingJulius Werner
This patch adds a new static assertion macro that can be used to check the offsets in structures that overlay register sets at compile time. It uses the _Static_assert() declaration from the new ISO C11 standard, which is supported (even without -std=c11) by GCC after version 4.6. (There is supposedly also support in clang, although I haven't tried it... let's deal with compiler issues when/if they turn up.) I've added it to all structures for our current ARM SoCs for now, and I think every new register overlay we add going forward should use them (at least for the last member, but feel free to add more if you think it's useful).

2013-11-25Make ssize_t an actual ssize_tStefan Reinauer
In the process of getting rid of compiler includes during in coreboot and libpayload, we defined size_t and ssize_t ourselves, using a GCC macro for size_t: __SIZE_TYPE__. Unfortunately, there is no __SSIZE_TYPE__, so we temporarily redefine unsigned to signed to make __SIZE_TYPE__ __SSIZE_TYPE__.

2013-03-16stddef.h: Add standard defines for KiB, MiB, GiB, and TiBRonald G. Minnich
Paul points out that some people like 1024*1024, others like 1048576, but in any case these are all open to typos. Define KiB, MiB, GiB, and TiB as in the standard so people can use them.

2012-12-08stddef.h: move to generic codeStefan Reinauer
stddef.h should be fairly generic across all platforms we'd want to support, so let's move it to generic code.
