fa1392a236 rockchip: reserve memory for rk3399 ATF data
There are 3 regions used by rk3399 ATF:
- bl31 code, located at 0x10000;
- cortex-m0 code and data, located at 0xff8c0000;
- bl31 data, located at 0xff8c1000 ~ 0xff8c4000;

SPL_TEXT_BASE starts from 0xff8c2000, we need to reserve memory
for ATF data, or else there will be memory corrupt after SPL
loads the ATF image.

More detail about cortex-M0 code in ATF:

This commit adds support for the pin-configuration of the SPI5
controller of the RK3399 through the following changes:
 * grf_rk3399.h: adds definition for configuring the SPI5 pins
   		 in the GPIO2C group
 * periph.h: defines PERIPH_ID_SPI3 through PERIPH_ID_SPI5
 * pinctrl_rk3399.c: adds the reverse-mapping from the IRQ# to
   		     PERIPH_ID_SPI5; dispatches PERIPH_ID_SPI3
		     through SPI5 to the appropriate pin-config
		     function; implements the pin-configuration
		     for PERIPH_ID_SPI5 using the GPIO2C group

7ee16de58b rockchip: rk3399: spl: add UART0 support for SPL
The RK3399-Q7 ("Puma") SoM exposes UART0 as the Qseven UART (i.e. the
serial line available via standardised pins on the edge connector and
available on a RS232 connector).

To support boards (such as the RK3399-Q7) that require UART0 as a
debug console, we match CONFIG_DEBUG_UART_BASE and add the appropriate
iomux setup to the rk3399 SPL code.

As we are already touching this code, we also move the board-specific
UART setup (i.e. iomux setup) into board_debug_uart_init(). This will
be called from the debug UART init when CONFIG_DEBUG_UART_BOARD_INIT
is set.

As the RK3399 needs to use its board_debug_uart_init() function, we
have Kconfig enable it by default for RK3399 builds.

With everything set up to define CONFIG_BAUDRATE via defconfig and
with to have the SPL debug UART either on UART0 or UART2, the configs
for the RK3399 EVB are then update (the change for the RK3399-Q7 is
left for later to not cause issues on applying the change).

1f08aa1c9f net: gmac_rockchip: Add support for the RK3399 GMAC
The GMAC in the RK3399 is very similar to the RK3288 variant (i.e. it
is a Designware GMAC core and requires similar configuration as the
RK3288 to switch it to RGMII and set up the TX/RX delays for Gigabit).
The key difference is that the register offsets (within the GRF block)
and bit-offsets (within those registers) used to hold the configuration
differ between the various RK32/33 CPUs.

This change refactors the gmac_rockchip.c driver to use a function
table (selected via driver_data) to factor out these differences. Each
function's implementation then matches the underlying processor.

Some collateral changes are needed in the definitions describing the
bits and offsets in the GRF are needed to prefix each set of symbolic
constants with the SoC name to avoid name clashes... and in doing so,
the shifts for masks and constants have been moved into the header
files for readability (and to make it easier to stay below 80 chars).

 * adds the required defines (in the GRF support) for configuring the

cc232a9d07 rockchip: video: Split out HDMI controller code
Designware HDMI controller and phy are used in other SoCs as well. Split
out platform independent code.

DW HDMI has 8 bit registers but they can be represented as 32 bit
registers as well. Add support to select access mode.

EDID reading code use reading by blocks which is not supported by other
SoCs in general. Make it more general using byte by byte approach, which
is also used in Linux driver.

Finally, not all DW HDMI controllers are accompanied with DW HDMI phy.
Support custom phys by making controller code independent from phy code.

f785357073 rockchip: clk: rk3188: Allow configuration of the armclk
The armclk starts in slow mode (24MHz) on the rk3188, which makes the whole
startup take a lot of time. We therefore want to at least move to the safe
600MHz value we can use with default pmic settings.
This is also the freqency the proprietary sdram-init leaves the cpu at.

For boards that have pmic control later in u-boot, we also add the option
to set the maximum frequency of 1.6GHz, if they so desire.

3d54eabcaf rockchip: spl: RK3399: use boot0 hook to create space for SPL magic
The SPL binary needs to be prefixed with the boot magic ('RK33' for
the RK3399) on the Rockchip platform and starts execution of the
instruction word following immediately after this boot magic.

This poses a challenge for AArch64 (ARMv8) binaries, as the .text
section would need to start on the odd address, violating natural
alignment (and potentially triggering a fault for any code that
tries to access 64bit values embedded in the .text section).

A quick and easy fix is to have the .text section include the 'RK33'
magic and pad it with a boot0 hook to insert 4 bytes of padding at the
start of the section (with the intention of having mkimage overwrite
this padding with the appropriate boot magic). This avoids having to
modify the linker scripts or more complex logic in mkimage.

3e747197b1 rockchip: rk3188: Add sdram driver
The sdram controller blocks are very similar to the rk3288 in utilizing
memory scheduler, Designware uPCTL and Designware PUBL blocks, only
limited to one bank instead of two.

There are some minimal differences when setting up the ram, so it gets
a separate driver for the rk3188 but reuses the driver structs, as there
is no need to define the same again.

More optimization can happen when the modelling of the controller parts
in the dts actually follow the hardware layout hopefully at some point
in the future.

135aa95002 clk: convert API to match reset/mailbox style
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).

0aefc0b0c7 rockchip: rk3288: Add clock support for the gmac ethernet interface
Setup the clocks for the gmac ethernet interface. This assumes the mac
clock is fed by an external clock which is common on RK3288 based
devices.

8530783594 rockchip: video: Add LVDS support in vop driver
LVDS have a different display out mode, add code to get right flag.

The vop_ip decide display device and the remote_vop_id decide which
vop was being used. So we should use the remote_vop_id to set DCLK_VOP.

affd4a9fa0 rockchip: Tidy up the register-access macros
These work reasonable well, but there are a few errors:

- Brackets should be used to avoid unexpected side-effects
- When setting bits, the corresponding upper 16 bits should be set also
