* Move malloc_cache_aligned() to its own headerSimon Glass2015-09-11-1/+4
| | | | | | | | | | | | | | | | | | | At present malloc.h is included everywhere since it recently was added to common.h in this commit: 4519668 mtd/nand/ubi: assortment of alignment fixes This seems wasteful and unnecessary. We have been trying to trim down common.h and put separate functions into separate header files and that change goes in the opposite direction. Move malloc_cache_aligned() to a new header so that this can be avoided. The header would perhaps be better named as alignmem.h but it needs to be included after common.h and people might be confused by this. With the name memalign.h it fits nicely after malloc() in most cases. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

| | | | | | | | | | | | | | | | | | | | It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.

I want kmalloc(size, __GFP_ZERO) to behave as kzalloc() does, which will make it easier to add more memory allocator variants.

* | blackfin: fix undefined reference to srand and randMasahiro Yamada2015-06-11-1/+3
|/ | | | | | | | | | | | | | | | | | | | | Commit 9ba9e85f3f1c (net: Fix NET_RANDOM_ETHADDR dependencies) accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards. Prior to that commit, those boards defined CONFIG_LIB_RAND, but not CONFIG_NET_RANDOM_ETHADDR. So, commit 9ba9e85f3f1c should not have touched them, but in fact it ripped CONFIG_LIB_RAND off from all the header files, which caused undefined reference to srand and rand. CONFIG_LIB_RAND=y must be revived for such boards. BTW, this commit indeed makes it better, but even with this fix, three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not build due to region 'ram' overflowed error. This was cause by commit 6eed3786c68c (net: Move the CMD_NET config to defconfigs) because CMD_NET selects NET, and NET selects REGEX. Eventually, some boards were newly enabled with CONFIG_REGEX, increasing the memory footprint. A patch is expected to fix the build error.
