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).

The RK3368 has both a limited TPL size (just 0x7000 bytes) and the
added challenge of booting in AArch64, which increases the code size

The back-to-bootrom support for Rockchip is equivalent to an
(assembly) implementation of setjmp/longjmp (i.e. it saves the
stack-pointer, link-register and callee-saved registers). Up until
now, this had only been implemented for AArch32 (i.e. ARMv7 or older),
which puts the new ARMv8 devices (which boot in AArch64 mode) at a
slight disadvantage.
To allow use of the 'back-to-bootrom' feature on new devices (e.g. the

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
