I know it is in GNU LIBC; I also know it is not (yet...) in U-Boot's own C library. What about the most common toolchains used on U-Boot?
The memalign is already defined in the u-boot tree (common/dlmalloc.c).
The dlmalloc.o is also built during compilation and it is linked to the final u-boot binary.
I'm using the CodeSourgery's ARM toolchain (gcc version 4.4.1 (Sourcery G++ Lite 2009q3-68)). I can test it with (gcc version 4.3.2 (Sourcery G++ Lite 2008q3-72)) as well.
Moreover I can try to install OSELAS.Toolchain (PTXdist ones) and test this as well with those toolchains. There are several one available for armv5/armv6/armv7.
Initially I was planning to use calloc/malloc from ./common/dlmalloc.c but it is clearly stated, that it is using 8 bytes alignment (which is hardwired in this implementation).
I will keep you informed about the tests results.
