Almost all of the newer Allwinner SoCs have a new operating mode for the
eMMC clocks that needs to be enabled in both the clock and the MMC
controller.
Details about that mode are sparse, and the name itself (new mode vs old
mode) doesn't give much details, but it seems that the it changes the
sampling of the MMC clock. One side effect is also that it divides the
parent clock rate by 2.
Add support for it through a Kconfig option.

OMAP5432 did go into production with AVS class0 registers which were
mutually exclusive from AVS Class 1.5 registers.
Most OMAP5-uEVM boards use the pre-production Class1.5 which has
production efuse registers set to 0. However on production devices,
these are set to valid data.
scale_vcore logic is already smart enough to detect this and use the
"Nominal voltage" on devices that do not have efuse registers populated.
On a test production device populated as follows:
MPU OPP_NOM:
=> md.l 0x04A0021C4 1
4a0021c4: 03a003e9 ....
(0x3e9 = 1.01v) vs nom voltage of 1.06v
MPU OPP_HIGH:
=> md.l 0x04A0021C8 1
4a0021c8: 03400485 ..@.
MM OPP_NOM:
=> md.l 0x04A0021A4 1
4a0021a4: 038003d4 ....
(0x3d4 = 980mV) vs nom voltage of 1.025v
MM OPP_OD:
=> md.l 0x04A0021A8 1
4a0021a8: 03600403 ..`.
CORE OPP_NOM:
=> md.l 0x04A0021D8 1
4a0021d8: 000003cf ....
(0x3cf = 975mV) vs nom voltage of 1.040v
Since the efuse values are'nt currently used, we do not regress on
existing pre-production samples (they continue to use nominal voltage).
But on boards that do have production samples populated, we can leverage
the optimal voltages necessary for proper operation.
Tested on:
a) 720-2644-001 OMAP5UEVM with production sample.
b) 750-2628-222(A) UEVM5432G-02 with pre-production sample.

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).

To enable the GMAC on the RK3368, we need to set up the clocking
appropriately to generate a tx_clk for the MAC.
This adds an implementation that implements the use of the <&ext_gmac>
clock (i.e. an external 125MHz clock for RGMII provided by the PHY).
This is the clock setup used by the boards currently supported by
U-Boot (i.e. Geekbox, Sheep and RK3368-uQ7).

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.

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.

On the RK3368 we use a TPL-stage similar to Rockchip's DDR init
(i.e. it initialises DRAM, leaves some info for the next stage and
returns to the BootROM). To allow compatibility with Rockchip's DDR
init code, we use the same register os_reg2 in pmugrf for passing
this info (i.e. DRAM size and configuration) between stages.
This change adds the definitions for os_reg[0] through os_reg[3] to
the pmugrf structure for the RK3368.

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.
