* arm: imx: Pack u-boot.bin into uImage for SPLMarek Vasut2013-05-05-4/+10
| | | | | | | | | | | | | | | The U-Boot SPL can parse the uImage format and gather information from it about the payload. Make use of this and wrap u-boot.bin into uImage format. The benefit is the SPL will know the size of the payload instead of using fixed size of the payload defined at compile time.

* nand: Add SPL_NAND support to mxc_nand_splMarek Vasut2013-05-05-3/+10
| | | | | | | | | | | | | | | | | | | | Add support for generic NAND SPL via the SPL framework into the mxc_nand_spl driver. This is basically just a simple rename and publication of the already implemented functions. To avoid the bare-bones functions getting in the way of the NAND_SPL, build them only if CONFIG_SPL_FRAMEWORK is not defined. Also make sure the requested payload is aligned to full pages, otherwise this simple driver fails to load the last page.

* imx: Align the imximage header and payload to multiples of 4kMarek Vasut2013-05-05-5/+9
| | | | | | | | | | | | | | The MX53 ROM loads the data from NAND in multiples of pages and supports maximum page size of 4k. Thus, align the image and header to 4k to be safe from ROM bugs.

* mx23: Fix pad voltage selection bitFabio Estevam2013-05-05-0/+4
| | | | | | | | | | | | | | | | On mx23 the pad voltage selection bit needs to be always '0', since '1' is a reserved value. For example: Pin 108, EMI_A06 pin voltage selection: 0= 1.8V (mDDR) or 2.5V (DDR1); 1= reserved. Fix the pad voltage definitions for the mx23 case.

* tools: arm: imx: Implement BOOT_OFFSET command for imximageMarek Vasut2013-04-28-0/+60
| | | | | | | | | | | | | | | | | | | | Implement BOOT_OFFSET command for imximage. This command is parallel to current BOOT_FROM command, but allows more flexibility in configuring arbitrary image header offset. Also add an imximage.cfg with default offset values into arm/arch/imx-common/ so the board-specific imximage.cfg can include this file to avoid magic constants. The syntax of BOOT_OFFSET command is "BOOT_OFFSET <u32 offset>".

* 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.
