* arm: mx6: gw_ventana: Change clock init to enable NAND related clocksStefan Roese2014-12-19-1/+1
| | | | | | | | | | | | | | | Otherwise NAND booting is likely to fail. Since this disables the NAND related clocks and SPL can't load the main U-Boot from NAND.

| * fdt: Allow ft_board_setup() to report failureSimon Glass2014-11-21-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

* | gw_ventana: Use the generic spl_sd.cfgFabio Estevam2014-11-24-23/+0
| | | | | | | | | | | | | | | | | | | | | | gw_ventana can boot from SPI or NAND and both of these interfaces boot from the same 0x400 offset. This means that we could simplify the code and replace the custom gw_ventana.cfg with the generic spl_sd.cfg, as it provides the same boot offset of 0x400.

* kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj2014-10-29-3/+0
| | | | | | | | | | | | | | | | | This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

* | spi: mxc: fix sf probe when using mxc_spiNikita Kiryanov2014-09-24-1/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MXC SPI driver has a feature whereas a GPIO line can be used to force CS high across multiple transactions. This is set up by embedding the GPIO information in the CS value: cs = (cs | gpio << 8) This merge of cs and gpio data into one value breaks the sf probe command: if the use of gpio is required, invoking "sf probe <cs>" will not work, because the CS argument doesn't have the GPIO information in it. Instead, the user must use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must type "sf probe 15872". This is inconsistent with the description of the sf probe command, and forces the user to be aware of implementaiton details. Fix this by introducing a new board function: board_spi_cs_gpio(), which will accept a naked CS value, and provide the driver with the relevant GPIO, if one is necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The IMX6 MMDC calibration registers depend on propagation delay and capacitive loading between the SoC's MMDC and the DDR3 chips. On the Ventana boards the board layout varies little in trace-lengths such that propagation delays are irrelevant thus we can simply things by using calibration values obtained from various board layouts based on a common SoC and DDR chip configuration. This eliminates board-model from being needed allowing more flexibility. These values were tested on a large sample size of Gateworks Ventana boards ranging in layout, and memory configuration over the entire temperature range supported.

| | | | | | | | | | | NAND devices have differing layouts with respect to page size and pages per block. These parameters affect the parameters that need to be passed to mkfs.ubifs and ubinize used to create UBI images. The various NAND chips supported by Gateworks Ventana fall into two different layouts which we refer to as 'normal' and 'large'. This layout is useful when referencing ubi files to download and flash so we create a dynamic env variable for it. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.
