| | | | | | | | | | | | | | | | | The file test.dts from driver model test directory, was compiled by call dtc in script: test/dm/test-dm.sh. This doesn't allow for including of dtsi files and using of C preprocessor routines in this dts file. Since the mentioned script builds U-Boot before tests, then moving the test.dts file into sandbox dts directory is reasonable.

* sandbox: Don't try distro_bootcmd by defaultSjoerd Simons2015-05-06-3/+18
| | | | | | | | | | | | For the distro_bootcmds to succeed on the sandbox a bit of setup is required (e.g. network configured or host image bound), so running them by default isn't that useful. Add a -b/--boot command to the sandbox binary, which triggers the distro_bootcmds to run after the other command-line commands.

* dm: select CONFIG_DM* optionsMasahiro Yamada2015-04-18-18/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* cros_ec: exynos: Match up device tree with kernel versionSimon Glass2015-04-18-90/+130
| | | | | | | | | | | The U-Boot device trees are slightly different in a few places. Adjust them to remove most of the differences. Note that U-Boot does not support the concept of interrupts as distinct from GPIOs, so this difference remains. For sandbox, use the same keyboard file as for ARM boards and drop the host emulation bus which seems redundant. Signed-off-by: Simon Glass <sjg@chromium.org>

* sandbox: eth: Add support for using the 'lo' interfaceJoe Hershberger2015-04-18-3/+127
| | | | | | | | | | | | | | | The 'lo' interface on Linux doesn't support thinks like ARP or link-layer access like we use to talk to a normal network interface. A higher-level network API must be used to access localhost. As written, this interface is limited to not supporting ICMP since the API doesn't allow the socket to be opened for all IP traffic and be able to receive at the same time. UDP is far more useful to test with, so it was selected over ICMP. Ping won't work, but things like TFTP should work.
