* kbuild: create a build directory automatically for out-of-tree buildMasahiro Yamada2014-03-28-1/+2
| | | | | | | | | | | | | | | | | | Prior to Kbuild, the build system created a build directory, when it did not exist, for out-of-tree build. This feature was dropped when we switched to Kbuild because many of lines in makefiles were copied from Linux Kernel. (In Linux Kernel, we have to create a build directory by ourselves before starting build.) That feature seems worth reviving for less typing even if our code and Linux Kernel diverge.

* kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/libMasahiro Yamada2014-03-28-358/+280
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.

| * mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou2014-03-24-396/+440
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long.

| | | | | | | | | | | | | | | | | SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.
