* | | | kbuild: use SoC-specific CONFIG to descend into SoC directoryMasahiro Yamada2014-11-23-8/+56

* | | | kbuild: Descend into SOC directory from CPU directoryMasahiro Yamada2014-11-23-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some CPUs of some architectures have SOC directories. At present, the build system directly descends into SOC directories from the top Makefile, but it should generally descend into each directory from its parent directory.

* | | | linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada2014-11-23-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>
* | | | include: move various macros to include/linux/kernel.hMasahiro Yamada2014-11-20-4/+0

In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux-compatible macro DIV_ROUND_CLOSEST is a bit more flexible and safer than DIV_ROUND.

SPL on the other hand is oblivious to this distinction, so once the bootROM loads SPL from the device configured in SRC_GPR10, SPL will attempt to load U-Boot from the device configured in SRC_SMBR1, which is not updated by the bootROM to the value in SRC_GPR9. The result is that the selected boot device is not used across all the boot stages. Update spl_boot_device() to look at gpr9 when necessary.
