* arm: mxs: Preprocess u-boot.bd so they contain full pathMarek Vasut2013-05-06-9/+17
| | | | | | | | | | | | | | | | The u-boot-imx23.bd and u-boot-imx28.bd need to be preprocessed, otherwise they have issues with out-of-tree build where elftosb tool couldn't sometimes find the u-boot.bin and spl/u-boot-spl.bin . Preprocess these .bd files with sed and insert full path to u-boot.bin and spl/u-boot-spl.bin to prevent this issue. Moreover, to avoid adding more churn into main Makefile, move all this preprocessing and u-boot.sb generation into CPU directory instead.

* arm: mx23: Fix VDDMEM misconfigurationMarek Vasut2013-05-06-20/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | The VDDMEM ramped up in very weird way as it was horribly misconfigured. Instead of setting up VDDMEM in one swipe, let it rise slowly the same way as VDDD and VDDA in spl_power_init.c and then only clear ILIMIT before memory gets inited. This makes sure the VDDMEM rises sanely, not jumps up and down as it did till now. The VDDMEM prior to this change did this: 2V0____ .--------2V5 | `--' 0V____| The VDDMEM now does this: 2V0_____,-----------2V5 / 0V__| Moreover, VDDIO on MX23 uses 25mV steps while MX28 uses 50mV steps, fix this difference too.

* imx: iomux-v3: Include PKE and PUE to pad control pull definitionsBenoît Thébaudeau2013-04-28-110/+82
| | | | | | | | | | | | | | | | | PUE requires PKE to mean something, as do pull values with PUE, so do not compell users to explicitly use PKE and PUE everywhere. This is also what is done on Linux and what has already been done for i.MX51. By the way, remove some unused pad control definitions. There is no change of behavior. Note that SPI_PAD_CTRL was defined by several boards with a pull value, but without PKE or PUE, which means that no pull was actually enabled in the pad. This might be a bug in those boards, but this patch does not change the behavior, so it just removes the meaningless pull value from those definitions.
