2016-07-14rockchip: sdram: Update the driver to support of-platdataSimon Glass
Add support for of-platdata with rk3288 SDRAM initr. This requires decoding the of-platdata struct and setting up the device from that. Also the driver needs to be renamed to match the string that of-platdata will search for. The platform data is copied from the of-platdata structure to the one used by the driver. This allows the same code to be used with device tree and of-platdata. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-07-14rockchip: sdram: Move all DT decoding to ofdata_to_platdata()Simon Glass
It is more correct to avoid touching the device tree in the probe() method. Update the driver to work this way. Note that only SPL needs to fiddle with the SDRAM registers, so decoding the platform data fully is not necessary in U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-07-14rockchip: syscon: Update to work with of-platdataSimon Glass
The syscon devices all end up having diffent driver names with of-platdata, since the driver name comes from the first string in the compatible list. Add separate device declarations for each one, and add a bind method to set up driver_data correctly. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-07-14sandbox: Add a test device that uses of-platdataSimon Glass
Start up the test devices. These print out of-platdata contents, providing a check that the of-platdata feature is working correctly. The device-tree changes are made to sandbox.dts rather than test.dts. since the former controls the of-platdata generation. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-07-14sandbox: Add a new sandbox_spl boardSimon Glass
It is useful to be able to build SPL for sandbox. It provides additional build coverage and allows SPL features to be tested in sandbox. However it does not need worthwhile to always create an SPL build. It nearly doubles the build time and the feature is (so far) seldom used. So for now, create a separate build target for sandbox SPL. This allows experimentation with this new feature without impacting existing workflows. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-07-14sandbox: Allow chaining from SPL to U-Boot properSimon Glass
SPL is expected to load and run U-Boot. This needs to work with sandbox also. Provide a function to locate the U-Boot image, and another to start it. This allows SPL to function on sandbox as it does on other archs. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-07-14stm32: Change USART port to USART6 for stm32f746 discovery boardToshifumi NISHINAGA
This change is to remove a halt at about 200KiB while sending a large(1MiB) binary to a micro controller using USART1. USART1 is connected to a PC via an on-board ST-Link debugger that also functions as a USB-Serial converter. However, it seems to loss some data occasionally. So I changed the serial port to USART6 and connected it to the PC using an FTDI USB-Serial cable, therefore the transmission was successfully completed.

2016-07-14sandbox: Don't exit when bootm completesSimon Glass
At present sandbox exits when the 'bootm' command completes, since it is not actually able to run the OS that is loaded. Normally 'bootm' failure is considered a fatal error in U-Boot. However this is annoying for tests, which may want to examine the state after a test is complete. In any case there is a 'reset' command which can be used to exit, if required. Change the behaviour to return normally from the 'bootm' command on sandbox. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Teddy Reed <teddy.reed@gmail.com>
2016-07-14linux/io.h: add generic ioremap()/iounmap() definesMasahiro Yamada
For most of architectures in U-Boot, virtual address is straight mapped to physical address. So, it makes sense to have generic defines of ioremap and friends in <linux/io.h>. All of them are just empty and will disappear at compile time, but they will be helpful to implement drivers which are counterparts of Linux ones. I notice MIPS already has its own implementation, so I added a Kconfig symbol CONFIG_HAVE_ARCH_IOREMAP which MIPS (and maybe Sandbox as well) can select.

Currently, this is only defined in arch/arm/include/asm/types.h, so move it to include/linux/types.h to make it available for all architectures. I defined it with phys_addr_t as Linux does. I needed to surround the define with #ifdef __KERNEL__ ... #endif to avoid build errors in tools building. (Host tools should not include <linux/types.h> in the first place, but this is already messy in U-Boot...)

2016-07-14arm64: add better and more generic spin-table supportMasahiro Yamada
There are two enable methods supported by ARM64 Linux; psci and spin-table. The latter is simpler and helpful for quick SoC bring up. My main motivation for this patch is to improve the spin-table support, which allows us to boot an ARMv8 system without the ARM Trusted Firmware. Currently, we have multi-entry code in arch/arm/cpu/armv8/start.S and the spin-table is supported in a really ad-hoc way, and I see some problems: - We must hard-code CPU_RELEASE_ADDR so that it matches the "cpu-release-addr" property in the DT that comes from the kernel tree. - The Documentation/arm64/booting.txt in Linux requires that the release address must be zero-initialized, but it is not cared by the common code in U-Boot. We must do it in a board function. - There is no systematic way to protect the spin-table code from the kernel. We are supposed to do it in a board specific manner, but it is difficult to predict where the spin-table code will be located after the relocation. So, it also makes difficult to hard-code /memreserve/ in the DT of the kernel. So, here is a patch to solve those problems; the DT is run-time modified to reserve the spin-table code (+ cpu-release-addr). Also, the "cpu-release-addr" property is set to an appropriate address after the relocation, which means we no longer need the hard-coded CPU_RELEASE_ADDR.
