9e92116bc8 rockchip: Add support for chromebook_bob
Bob is a 10-inch chromebook produced by Asus. It has two USB 3.0 type-C
ports, 4GB of SDRAM, WiFi and a 1280x800 display. It uses its USB ports
for both power and external display. It includes a Chrome OS EC
(Cortex-M3) to provide access to the keyboard and battery functions.

Support so far includes only:
- UART
- SDRAM
- MMC, SD card
- Cros EC (but not keyboard)

Not included:
- Keyboard
- Display
- Sound
- USB
- TPM

Bob is quite similar to Kevin, the Samsung Chromebook Plus, but support
for this is not provided in this series.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

ecfd71891a rockchip: back-to-bootrom: replace assembly-implementation with C-code
The back-to-bootrom implementation for Rockchip has always relied on
the stack-pointer being valid on entry, so there was little reason to
have this as an assembly implementation.

This provides a new C-only implementation of save_boot_params and
back_to_bootrom (relying on setjmp/longjmp) and removes the older
assembly-only implementation.

b377d22264 rockchip: boot0 hook: support early return for RK3188/RK3066-style BROM
Some Rockchip BROM versions (e.g. the RK3188 and RK3066) first read 1KB data
from NAND into SRAM and executes it. Then, following a return to bootrom, the
BROM loads additional code to SRAM (not overwriting the first block read) and
reenters at the same address as the first time.

To support booting either a TPL (on the RK3066) or SPL (on the RK3188) using
this model of having to count entries, this commit adds code to the boot0
hook to track the number of entries and handle them accordingly.

The boot0 hook on ARM does not insert its payload before the vector

contradict usage of the boot0 hook on ARM64.

To fix this (and unify the semantics for ARM and ARM64), we change the
boot0-hook semantics on ARM to match those on ARM64:
  (1) if a boot0-hook is present it is inserted at the start of
      the image
  (2) if a boot0-hook is present, emitting the ARM vector table

403e9cbcd5 rockchip: rk3368: add DRAM controller driver with DRAM initialisation
This adds a DRAM controller driver for the RK3368 and places it in
drivers/ram/rockchip (where the other DM-enabled DRAM controller
drivers for rockchip devices should also be moved eventually).

At this stage, only the following feature-set is supported:
 - DDR3
 - 32-bit configuration (i.e. fully populated)
 - dual-rank (i.e. no auto-detection of ranks)
 - DDR3-1600K speed-bin

This driver expects to run from a TPL stage that will later return to
the RK3368 BROM.  It communicates with later stages through the
os_reg2 in the pmugrf (i.e. using the same mechanism as Rockchip's DDR
init code).

Unlike other DMC drivers for RK32xx and RK33xx parts, the required
timings are calculated within the driver based on a target frequency
and a DDR3 speed-bin (only the DDR3-1600K speed-bin is support at this
time).

The RK3368 also has the DDRC0_CON0 (DDR ch. 0, control-register 0)
register for controlling the operation of its (single-channel) DRAM
controller in the GRF block.  This provides for selecting DDR3, mobile
DDR modes, and control low-power operation.
As part of this change, DDRC0_CON0 is also added to the GRF structure
definition (at offset 0x600).

f5a432959a rockchip: clk: rk3368: implement MMC/SD clock reparenting
The original clock support for MMC/SD cards on the RK3368 suffered
from a tendency to select a divider less-or-equal to the the one
giving the requested clock-rate: this can lead to higher-than-expected
(or rather: higher than supported) clock rates for the MMC/SD
communiction.

This change rewrites the MMC/SD clock generation to:
 * always generate a clock less-than-or-equal to the requested clock
 * support reparenting among the CPLL, GPLL and OSC24M parents to
   generate the highest clock that does not exceed the requested rate

In addition to this, the Linux DTS uses HCLK_MMC/HCLK_SDMMC instead of
SCLK_MMC/SCLK_SDMMC: to match this (and to ensure that clock setup
always works), we adjust the driver appropriately.

This includes the changes from:

On he RK3368, we need to temporarily disable security on the DMA
engines during TPL and SPL to allow the MMC host to DMA into DRAM.  To
do so, we need to reset the two DMA engines, which in turn requires
the DMA1_SRST_REQ and DMA2_SRST_REQ constants to refer to the
appropriate bits in the CRU.

As the ATF correctly initialises security (and only leaves EL3 after
doing so), this can not pose a security issue.

700f3108d3 rockchip: spl: make boot0 hook TPL safe
When building for a TPL/SPL setup (e.g. on the RK3368), we need the
TPL stage to have the extra space for for the 'Rockchip SPL name'
(i.e. 'RK33' word).  Yet, the SPL will start execution at its first
word (i.e. the first word in the SPL binary needs to be a valid
instruction).  To make things a bit more involved, CONFIG_SPL_BUILD
is defined both for the SPL and the TPL stage.

To avoid having to explicitly test for the first stage (TPL, if and
only if TPL and SPL are built, SPL otherwise), this commit modifies
the sequence to repeat the 'b reset' (instead of reserving 4 bytes
of undefined space) at the start of the boot0 hook: if overwritten
(and execution starts at the second word), the first instruction is
still a 'b reset'... if not overwritten, we start on a 'b reset' as
well.

This solution wouldn't even require the check whether we are in the
SPL/TPL build (i.e. CONFIG_SPL_BUILD), but we leave this check in for
documentation purposes.

the RK3288... this configuration aspect is reflected by the driverdata
for the RK3399 driver.

Having some sort of DTS-based configuration for the regulator
dependencies would be nice for the future, but for now we simply use
lists of regulator names (also via driverdata) that we probe.

cc75afc5d7 rockchip: video: rk3399: enable HDMI output (from the rk_vop) for the RK3399
This commit adds a driver for the RK3399 VOPs capable and all the
necessary plumbing to feed the HDMI encoder. For the VOP-big, this
correctly tracks the ability to feed 10bit RGB data to the encoder.

d46d40474a rockchip: video: refactor rk_vop and split RK3288-specific code off
To prepare for adding the RK3399 VOP driver (which shares most of its
registers and config logic with the RK3228 VOP), this change refactors
the driver and splits the RK3288-specific driver off.

The changes in detail are:
- introduces a data-structure for chip-specific drivers to register
  features/callbacks with the common driver: at this time, this is
  limited to a callback for setting the pin polarities (between the
  VOP and the encoder modules) and a flag to signal 10bit RGB
  capability
- refactors the probing of regulators into a helper function that
  can take a list of regulator names to probe and autoset
- moves the priv data-structure into a (common) header file to be
  used by the chip-specific drivers to provide base addresses to
  the common driver
- uses a callback into the chip-specific driver to set pin polarities
  (replacing the direct register accesses previously used)
- splits enabling the output (towards an encoder) into a separate
  help function withint the common driver

fefe9d06bd rockchip: rk3288: grf: Fix shift for RK3288_TXCLK_DLY_ENA_GMAC_ENABLE
RK3288_TXCLK_DLY_ENA_GMAC_ENABLE, in GRF_SOC_CON3, is supposed to be bit
0xe and not 0xf. Otherwise, it is RGMII RX clock delayline enable and
introduces random delays and data lose.

This commit fixes the issue by replacing RK3288_TXCLK_DLY_ENA_GMAC_ENABLE
with the right shift.

077eb31514 rockchip: pinctrl: rk3328: do not set io routing
In rk3328, some function pin may have more than one choice, and muxed
with more than one IO, for example, the UART2 controller IO,
TX and RX, have 3 choice(setting in com_iomux):
- M0 which mux with GPIO1A0/GPIO1A1
- M1 which mux with GPIO2A0/GPIO2A1
- usb2phy which mux with USB2.0 DP/DM pin.

We should not decide which group to use in pinctrl driver,
for it may be different in different board, it should goes to board
file, and the pinctrl file should setting correct iomux depends on
the com_iomux value.
