* sandbox, x86: select DM_KEYBOARD instead of default y entryMasahiro Yamada2016-10-01-0/+2
| | | | | | | | | | Once we migrate to DM-based drivers, we cannot go back to legacy ones, i.e. config options like DM_* are not user-configurable. Make SANDBOX and X86 select DM_KEYBOARD like other platforms do. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* xtensa: add support for the xtensa processor architecture [2/2]Chris Zankel2016-08-15-0/+6
| | | | | | | | | | | | | The Xtensa processor architecture is a configurable, extensible, and synthesizable 32-bit RISC processor core provided by Tensilica, inc. This is the second part of the basic architecture port, adding the 'arch/xtensa' directory and a readme file.

* linux/io.h: add generic ioremap()/iounmap() definesMasahiro Yamada2016-07-14-0/+4
| | | | | | | | | | | | | | | | | For most of architectures in U-Boot, virtual address is straight mapped to physical address. So, it makes sense to have generic defines of ioremap and friends in <linux/io.h>. All of them are just empty and will disappear at compile time, but they will be helpful to implement drivers which are counterparts of Linux ones. I notice MIPS already has its own implementation, so I added a Kconfig symbol CONFIG_HAVE_ARCH_IOREMAP which MIPS (and maybe Sandbox as well) can select.

* dm: select CONFIG_DM* optionsMasahiro Yamada2015-04-18-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As mentioned in the previous commit, adding default values in each Kconfig causes problems because it does not co-exist with the "depends on" syntax. (Please note this is not a bug of Kconfig.) We should not do so unless we have a special reason. Actually, for CONFIG_DM*, we have no good reason to do so. Generally, CONFIG_DM is not a user-configurable option. Once we convert a driver into Driver Model, the board only works with Driver Model, i.e. CONFIG_DM must be always enabled for that board. So, using "select DM" is more suitable rather than allowing users to modify it. Another good thing is, Kconfig warns unmet dependencies for "select" syntax, so we easily notice bugs. Actually, CONFIG_DM and other related options have been added without consistency: some into arch/*/Kconfig, some into board/*/Kconfig, and some into configs/*_defconfig. This commit prefers "select" and cleans up the following issues. [1] Never use "CONFIG_DM=n" in defconfig files It is really rare to add "CONFIG_FOO=n" to disable CONFIG options. It is more common to use "# CONFIG_FOO is not set". But here, we do not even have to do it. Less than half of OMAP3 boards have been converted to Driver Model. Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is weird. Instead, add "select DM" only to appropriate boards, which eventually eliminates "CONFIG_DM=n", etc. [2] Delete redundant CONFIGs Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again in configs/sandbox_defconfig. Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and defines it also in omap3_beagle_defconfig and devkit8000_defconfig. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* arc: build libgcc in U-BootAlexey Brodkin2015-02-09-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This way we may have very limited set of functions implemented so we save some space. Also it allows us to build U-Boot for any ARC core with the same one toolchain because we don't rely on pre-built libgcc. For example: * we may use little-endian toolchain but build U-Boot for ether endianess * we may use non-multilibbed uClibc toolchain but build U-Boot for whatever ARC CPU flavour that current GCC supports Private libgcc built from generic C implementation contributes only 144 bytes to .text section so we don't see significant degradation of size: --->8--- $ arc-linux-size u-boot.libgcc-prebuilt text data bss dec hex filename 222217 24912 214820 461949 70c7d u-boot.libgcc-prebuilt $ arc-linux-size u-boot.libgcc-private text data bss dec hex filename 222361 24912 214820 462093 70d0d u-boot.libgcc-private --->8--- Also I don't notice visible performance degradation compared to pre-built libgcc (where at least "*div*" functions are had-written in assembly) on typical operations of downloading 10Mb uImage over TFTP and bootm.
