Instead of creating a rockchip SPL SD card image with 32KB of zeros which can be written to the start of an SD card, create the images with only the useful data that should be written to an offset of 32KB on the SD card. The first 32 kilobytes aren't needed for bootup and only serve as convenient way of accidentally obliterating your partition table.

Booting the kernel fails on RK3288 (and probably other rockchip SoCs) when the i-cache is disabled/flushed before d-cache. I have not investigated whether this is due to U-Boot hanging or whether it's very early in the linux boot, but following the approach of the various rockchip U-Boot forks (first disable d-cache then i-cache) makes things work.

Now that MMC works in U-Boot add config distro command support to start Linux in a standard fashion. One oddity here is that linux fails to load when the fdt is relocated to above 512MB, so set fdt_high to make sure it's loaded below that.

With LED support enabled the SPL easily goes over the size limit (e.g. with both Debians gcc 4.9 and 5.2 cross-compilers). Turn off LED support in the SPL to reduce the size just enough for those compilers.

The Rockchip boot ROM requires a particular file format for booting from SPI. It consists of a 512-byte header encoded with RC4, some padding and then up to 32KB of executable code in 2KB blocks, separated by 2KB empty blocks. Add support to mkimage so that an SPL image (u-boot-spl-dtb.bin) can be converted to this format. This allows booting from SPI flash on supported machines.

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: NSimon Glass <sjg@chromium.org>

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: NSimon Glass <sjg@chromium.org>

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: NSimon Glass <sjg@chromium.org>
