* buildman: Add documentation about the .buildman fileSimon Glass2015-01-14-20/+53
| | | | | | | This file is only partially documented. Add some more details. Signed-off-by: Simon Glass <sjg@chromium.org> Suggested-by: Wolfgang Denk <wd@denx.de>
* buildman: Add a note about Python pre-requisitesSimon Glass2015-01-14-1/+10
| | | | | | | | Since we need a few modules which might not be available in a bare-bones distribution, add a note about that to the README. Signed-off-by: Simon Glass <sjg@chromium.org> Suggested-by: Wolfgang Denk <wd@denx.de>
* buildman: Add an option to use the full tool chain pathSimon Glass2015-01-14-10/+25
| | | | | | | | | | | | | | In some cases there may be multiple toolchains with the same name in the path. Provide an option to use the full path in the CROSS_COMPILE environment variable. Note: Wolfgang mentioned that this is dangerous since in some cases there may be other tools on the path that are needed. So this is set up as an option, not the default. I will need test confirmation (i.e. that this commit fixes a real problem) before merging it. Signed-off-by: Simon Glass <sjg@chromium.org> Suggested-by: Steve Rae <srae@broadcom.com>
* buildman: Put the toolchain path first instead of last in PATHSimon Glass2015-01-14-1/+1
| | | | | | | | | | | | | | | | If: 1. Toolchains A and B have the same filename 2. Toolchain A is in the PATH 3. Toolchain B is given in ~/.buildman and buildman uses it to build then buildman will add toolchain B to the end of its path but will not necessarily use it since U-Boot will find toolchain A first in the PATH. Try to fix this by putting the toolchain first in the path instead of last. Signed-off-by: Simon Glass <sjg@chromium.org>

* buildman: Don't remove entire output directory when testingSimon Glass2015-01-14-1/+2
| | | | | | | | When running tests the output directory is often wiped. This is only safe if a branch is being built. The output directory may contain other things besides the buildman test output. Signed-off-by: Simon Glass <sjg@chromium.org>
* buildman: Add an option to flatten output directory treesSimon Glass2015-01-14-6/+24
| | | | | | | | | | When building current source for a single board, buildman puts the output in <output_dir>/current/current/<board>. Add an option to make it use <output_dir>/<board> instead. This removes the unnecessary directories in that case, controlled by the --no-subdirs/-N option. Suggested-by: Tom Rini <trini@ti.com> Signed-off-by: Simon Glass <sjg@chromium.org>
* buildman: Try to guess the upstream commitSimon Glass2015-01-14-16/+67
| | | | | | | | | | | | | | | Buildman normally obtains the upstream commit by asking git. Provided that the branch was created with 'git checkout -b <branch> <some_upstream>' then this normally works. When there is no upstream, we can try to guess one, by looking up through the commits until we find a branch. Add a function to try this and print a warning if buildman ends up relying on it. Also update the documentation to match. Signed-off-by: Simon Glass <sjg@chromium.org> Suggested-by: Wolfgang Denk <wd@denx.de>
* buildman: Don't prune output space for 'current source' buildSimon Glass2015-01-14-0/+2
| | | | | | | | | | This is not needed since we always do a full (non-incremental) build. Also it might be dangerous since it will try to delete everything below the base directory. Fix this potentially nasty bug. Signed-off-by: Simon Glass <sjg@chromium.org>
* buildman: Put build in 'current', not 'current/current'Simon Glass2015-01-14-4/+3

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The voltage setting code knows it needs to call axp221_init before calling the various voltage setting functions. But users of axp utility functions like axp221_get_sid() do not know this, so the utility functions always call axp221_init() to ensure that the p2wi / rsb setup magic has been done. Since doing this repeatedly is quite expensive, add a check to axp221_init so that it only does the initialization once.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the pre-console buffer can accumulate early log messages and flush them to the serial console as soon as it becomes available. This patch just adds one more pre-console buffer flushing point and does all the same for the other consoles too. This is particularly useful for the vga/hdmi/lcd console, where we can see all the older messages now (except for the log messages from SPL). Naturally, we don't want to get an extra copy of the log messages on the serial console again at the second flushing point, so the serial console has to be explicitly filtered out.

| | | | | | | | | | | | | | | | | | | | | | | | | | In some extreme cases it may be necessary to wait 1.5 seconds or more for a hpd signal to show up (and be able to read edid info), but we do not want to penalize all headless boots with an extra second boot delay, so add a hpd_delay parameter which can be set through the video-mode env. variable.

Also add LCD timing and gpio info for the Olimex 7" LCD module.

* | sunxi: gpio: Add support for gpio pins on the AXP209 pmicHans de Goede2015-01-14-0/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some boards use GPIO-s on the pmic, one example of this is the A13-OLinuXino board, which uses gpio0 of the axp209 for the lcd-power signal. This commit adds support for gpio pins on the AXP209 pmic, the sunxi_gpio.c changes are universal, adding gpio support for the other AXP pmics (when necessary) should be a matter of adding the necessary axp_gpio_foo functions to their resp. drivers, and add "#define AXP_GPIO" to their header file. Note this commit only adds support for the non device-model version of the gpio code, patches for adding support to the device-model version are very welcome. The string representation for these gpio-s is AXP0-#, the 0 in the AXP0 prefix is there in case we need to support gpio-s on more then 1 pmic in the future. At least A80 boards have 2 pmics, and we may end up needing to support gpio-s on both. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
