2011-10-27mx31: provide readable WEIM CS accessorHelmut Raiger
setup_weimcs() and some macros are added to support the setup for i.MX31 WEIM chip selects. As a compromise between verbosity and readability an ASCII-art'ish bit comment is used instead of bitfields. All i.MX31 boards have been patched to use this approach using a helper program to verify the changes. Signed-off-by: Helmut Raiger <helmut.raiger@hale.at> Acked-by: Stefano Babic <sbabic@denx.de>
2011-10-27tegra2: Add more pinmux functionsSimon Glass
This adds support for changing pinmux functions of pin groups. This is done by defining a PMUX_FUNC_... enum which can be used to select the function for each group using pinmux_set_func(). It is also possible to enable pullup/pulldown, and the existing tristate functionality is retained. Also provided is a means of configuring a list of pingroups by providing a configuration table to pinmux_config_table().

2011-10-27tegra2: Rename PIN_ to PINGRP_Simon Glass
The pin groupings are better named PINGRP, since on Tegra2 they refer to multiple pins. Sorry about this, but better to get it right now when there is only a small amount of code affected. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Tom Warren <twarren@nvidia.com>
2011-10-27tegra2: Add more clock functionsSimon Glass
This adds most of the clock functions required by board and driver code: -query and adjust peripheral clocks -query and adjust PLLs -reset and enable control These functions are plumbed in as required. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Tom Warren <twarren@nvidia.com>
2011-10-27tegra2: Rename CLOCK_PLL_ID to CLOCK_IDSimon Glass
Rename CLOCK_PLL_ID to CLOCK_ID which takes account of the fact that the code now deals with both PLL clocks and source clocks. This also tidied up the assert() to match the one sent upstream, and fixes an error in the PWM id. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Tom Warren <twarren@nvidia.com>
2011-10-22build: add missing $(AR)->$(cmd_link_o_target) updateMike Frysinger

2011-10-17Move timestamp and version files into 'generated' subdirSimon Glass
There is a rather subtle build problem where the build time stamp is not updated for out-of-tree builds if there exists an in-tree build which has a valid timestamp file. So if you do an in-tree build, then an out-of-tree build your timestamp will not change. The correct timestamp_autogenerated.h lives in the object tree, but it is not always found there. The source still lives in the source tree and when compiling version.h, it includes timestamp_autogenerated.h. Since the current directory is always searched first, this will come from the source tree rather than the object tree if it exists there. This affects dependency generation also, which means that common/cmd_version.o will not even be rebuilt if you have ever done an in-tree build. A similar problem exists with the version file. This change moves both files into the 'generated' subdir, which is already used for asm-offsets.h. Then timestamp.h and version.h are updated to include the files from there. There are other places where these generated files are included, but I cannot see why these don't just use the timestamp.h and version.h headers. So this change also tidies that up. I have tested this with in- and out-of-tree builds, but not SPL. I have looked at various other options for fixing this, including sed on the dep files, -I- and -include flags to gcc, but I don't think they can be made to work. Comments welcome.
