2016-07-15rockchip: 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>
2016-07-15rockchip: 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>
2016-07-15rockchip: 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>
2016-07-15rockchip: Don't use spl_boot_device() with of-platdataSimon Glass
This function cannot look at the device tree when of-platdata is used. Update the code to handle this. Signed-off-by: Simon Glass <sjg@chromium.org>

When the boot ROM sets up MMC we don't need to do it again. Remove the MMC setup code entirely. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-07-11rockchip: Use 'select' instead of defaults in KconfigSimon Glass
Rockchip uses driver model for all subsystems. Specify this in the arm Kconfig rather than as defaults in the Rockchip Kconfig. This means that boards cannot turn these options off, which seems correct. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-06-26common: Pass the boot device into spl_boot_mode()Marek Vasut
The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

2016-06-19clk: convert API to match reset/mailbox styleStephen Warren
The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

2016-05-27Rename reset to sysresetStephen Warren
The current reset API implements a method to reset the entire system. In the near future, I'd like to introduce code that implements the device tree reset bindings; i.e. the equivalent of the Linux kernel's reset API. This controls resets to individual HW blocks or external chips with reset signals. It doesn't make sense to merge the two APIs into one since they have different semantic purposes. Resolve the naming conflict by renaming the existing reset API to sysreset instead, so the new reset API can be called just reset.

The DMC driver in v3.14 kernel[0] get the ddr setting from PMU_SYS_REG2, and it expects uboot to store the value using a same protocol. But now the ddr setting value is different with DMC, so if you enable the DMC, system would crash in kernel. Correct the sdram setting here, according to the requirements of kernel.

2015-12-01rockchip: move SYS_MALLOC_SIMPLE to mach-rockchip KconfigAriel D'Alessandro
Commit 1eb0c03c2198a7ec9de456b83dacdc4831b96cbf added SPL_SYS_MALLOC_SIMPLE Kconfig option and changed the way it is evaluated. Thus, the definitions of CONFIG_SYS_MALLOC_SIMPLE in rk3***_common.h board configs are now incorrect because CONFIG_SPL_BUILD is enabled so CONFIG_IS_ENABLED(SYS_MALLOC_SIMPLE) will look for SPL_SYS_MALLOC_SIMPLE instead of SYS_MALLOC_SIMPLE.

2015-10-03rockchip: Reconfigure the malloc based to point to system memorySjoerd Simons
When malloc_base initially gets setup in the SPL it is based on the current (early) stack pointer, which for rockchip is pointing into SRAM. This means simple memory allocations happen in SRAM space, which is somewhat unfortunate. Specifically a bounce buffer for the mmc allocated in SRAM space seems to cause the mmc engine to stall/fail causing timeouts and a failure to load the main u-boot image. To resolve this, reconfigure the malloc_base to start at the relocated stack pointer after DRAM has been setup. For reference, things did work fine on rockchip before 596380db was merged to fix memalign_simple due to a combination of rockchip SDRAM starting at address 0 and the dw_mmc driver not checking errors from bounce_buffer_start. As a result, when a bounce buffer needed to be allocated mem_align simple would fail and return NULL. The mmc driver ignored the error and happily continued with the bounce buffer address being set to 0, which just happened to work fine..
