2014-02-26arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini
When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.

2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

2014-02-19kbuild: change out-of-tree buildMasahiro Yamada
This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <[email protected]> Tested-by: Gerhard Sittig <[email protected]>

2014-02-03mmc: tegra: support Tegra124Stephen Warren
Tegra124's MMC controller is very similar to earlier SoC generations, and can be supported by the same driver. However, there are some non-backwards-compatible HW differences, and hence a new DT compatible value must be used to describe the HW. This patch updates the driver to support that new compatible value. That said, the HW differences are only relevant when enabling certain high-performance transfer modes. Since the driver is currently very simple and doesn't enable those modes, we don't actually need to address any of these HW differences in the code yet, hence the simple nature of this patch.

2014-01-24lib: fix return codes when CONFIG_SYS_VSNPRINTF is enabledDarwin Rambo
When CONFIG_SYS_VSNPRINTF is enabled, it protects print operations such as sprintf, snprintf, vsnprintf, etc., from buffer overflows. But vsnprintf_internal includes the terminating NULL character in the calculation of number of characters written. This affects sprintf and snprintf return values.

2013-12-13time: fix usec_to_tick()Stephen Warren
Commit 8dfafdde88eb ("Introduce common timer functions") created a common definition of usec_to_tick() which had a couple problems: static unsigned long long usec_to_tick(unsigned long usec) { uint64_t tick = usec * get_tbclk(); That likely overflows. usec *= get_tbclk(); That was an attempt to fix it by performing the multiply after the promotion of usec to 64-bit, but was applied to the wrong variable, which was never used. This patch fixes these issues. A user-visible symptom of the problem was the e.g. "dhcp zImage" using an ASIX USB Ethernet dongle would print: Waiting for Ethernet connection... unable to connect. ... with no delay before "unable to connect". There are likely other symptoms. Signed-off-by: Stephen Warren <[email protected]> Acked-by: Rob Herring <[email protected]>
