* dm: Provide better debugging when a device fails to bindSimon Glass2015-09-02-1/+4
| | | | | | | | | | All devices should bind without error. But when they don't, they can cause driver model init to fail. A real situation where this can happen is when there is a missing uclass. Add a debug() call to dm_scan_fdt_node to make this easier to track. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Improve handling of a missing uclassSimon Glass2015-09-02-2/+9
| | | | | | | | | | | | | | | When a uclass definition is missing, no drivers in that uclass can operate. This can happen if a board has a strange collection of options (e.g. the driver is enabled but the uclass is not). Unfortunately this is very confusing at present. Starting up driver model results in a -ENOENT error, which is pretty generic. Quite a big of digging is needed to get to the root cause. To help with this, change the error to a very strange one with no other users in U-Boot. Also add a debug message. Signed-off-by: Simon Glass <sjg@chromium.org>

* pinctrl: Add the concept of peripheral IDsSimon Glass2015-09-02-9/+31
| | | | | | | | | | | | | | | | | | | | | | | | | My original pinctrl patch operating using a peripheral ID enum. This was shared between pinmux and clock and provides an easy way to specify a device that needs to be controlled, even it is does not (yet) have a driver within driver model. Masahiro's new simple pinctrl gets around this by providing a set_state_simple() pinctrl method. By passing a device to that call the peripheral ID becomes unnecessary. If the driver needs it, it can calculate it itself and use it internally. However this does not solve the problem for peripheral clocks. The 'pure' solution would be to pass a driver to the clock uclass also. But this requires that all devices should have a driver, and a struct udevide. Also a key optimisation of the clock uclass is allowing a peripheral clock to be set even when there is no device for that clock. There may be a better way to achive the same goal, but for now it seems expedient to add in peripheral ID to the pinctrl uclass. Two methods are added - one to get the peripheral ID and one to select it. The existing set_state_simple() is effectively the union of these. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | Originally a timeout value of 2 seconds was used regardless of the size of data to be transfered. This prevented slow devices from working correctly while there was no much gain for faster devices, e.g. it takes 3708ms for a transfer of uImage of size 1899008 bytes.

Having this in Kconfig is useful because this is something which may differ from one board to the other even when using the same SoC.

| * sunxi_nand_spl: Remove NAND_SUNXI_SPL_SYNDROME_PARTITIONS_ENDHans de Goede2015-08-31-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We only ever use syndrome mode for the partitions which contain the SPL, as that is required for the BROM to be able to read the SPL. Instead of using some arbritray limit for deciding whether or not to use syndrome, be smart and check if u-boot-dtb.bin is directly behind the SPL, if it is not then it is on its own partition and we should not use syndrome. Note the reason why we only use syndrome mode for the SPL is because it comeswith weaker randomization, introducing a risk for more bit errors, so we want to avoid it when possible.

| * sunxi_nand_spl: Rename SPL_NAND_SUNXI to NAND_SUNXIHans de Goede2015-08-31-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We eventually want to add full nand support, since it makes no sense to build SPL with nand support and u-boot without, or the other way around, a single option will suffice. Renaming the Kconfig option now makes things easier when we add full nand support in the future. The "obj-$(CONFIG_NAND_SUNXI) += sunxi_nand_spl.o" is moved to an "ifdef CONFIG_SPL_BUILD" block in the Makefile.

| * sunxi_nand_spl: Add support for backup boot partitionsHans de Goede2015-08-31-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | The BROM does not care / use bad page markings, instead it deals with any bad pages in the first erase-block by simply trying to load "boot0" from the next erase-block. This commit implements the same strategy for the sunxi spl nand code, allowing it to boot from the backup boot partition when the main boot partition is bad (tested by erasing the main boot partition).

| * sunxi_nand_spl: Auto detect nand configuration parametersHans de Goede2015-08-31-29/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Auto detect the nand configuration parameters, like the BROM does. This allows us to get rid of various Kconfig settings, and is necessary to support generic boards like the mk802 which have seen many production runs with different nands. The full blown u-boot/kernel nand driver uses the nand id to determine this info, for the SPL we do as the BROM does and simply try a few standard configs. Note the table only contains configs which are known to actually be used, rather then all the configs the BROM tries. This means that it may need to be updated in the future as we add support for nand on more boards. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

Also the value currently being written is actual wrong, the ecc sits at "column + CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE" not just CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nand_spl_load_image() always gets called with either CONFIG_SYS_TEXT_BASE or spl_image.load_addr as destination, both of which are properly aligened, and have plenty of space for "overshooting" up to CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE bytes, as we read in CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE bytes chunks. This saves CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE (typically 1k) in SPL size, which is a lot on the total 24k we have. Note this changes the dma destination from SRAM to DRAM, so this patch updates the DDMA_DST_TYPE bits in the dma controller cfg0 reg accordingly.

This uclass handles pinmuxing and pin configuration; pinmuxing controls switching among silicon blocks that share certain physical pins, pin configuration handles electronic properties such as pin- biasing, load capacitance etc. This framework can support the same device tree bindings, but if you do not need full interface support, you can disable some features to reduce memory foot print. Typically around 1.5KB is necessary to include full-featured uclass support on ARM board (CONFIG_PINCTRL + CONFIG_PINCTRL_FULL + CONFIG_PINCTRL_GENERIC + CONFIG_PINCTRL_PINMUX), for example. We are often limited on code size for SPL. Besides, we still have many boards that do not support device tree configuration. The full pinctrl, which requires OF_CONTROL, does not make sense for those boards. So, this framework also has a Do-It-Yourself (let's say simple pinctrl) interface. With CONFIG_PINCTRL_FULL disabled, the uclass itself provides no systematic mechanism for identifying the peripheral device, applying pinctrl settings, etc. They must be done in each low-level driver. In return, you can save much memory footprint and it might be useful especially for SPL. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Simon Glass <sjg@chromium.org>
