Solved the overflow on phys_addr_t type for start + size in
mmu_set_region_dcache_behaviour() function.
This overflow is avoided by dividing start and end by 2 before addition,
and we only expecting that start and size are even.
This patch doesn't change the current function behavior if the
parameters (start or size) are not aligned on MMU_SECTION_SIZE.
For example, this overflow occurs on ARM32 with:
start = 0xC0000000 and size = 0x40000000
then start + size = 0x100000000 and end = 0x0.
For information the function behavior change with risk of regression,
if we just shift start and size before the addition.
Example with 2MB section size:
MMU_SECTION_SIZE 0x200000 and MMU_SECTION_SHIFT = 21
with start = 0x1000000, size = 0x1000000,
- with the proposed patch, start = 0 and end = 0x1 as previously
- with the more simple patch:
end = (start >> MMU_SECTION_SHIFT) + (size >> MMU_SECTION_SHIFT)
the value of end change:
start >> 21 = 0, size >> 21 = 0 and end = 0x0 !!!

Add the new flags DCACHE_DEFAULT_OPTION to define the default
option to use according the compilation flags
CONFIG_SYS_ARM_CACHE_*.
This new compilation flag allows to simplify dram_bank_mmu_setup()
and can be used as third parameter (option=dcache option to select)
of mmu_set_region_dcache_behaviour function.

Add protection in dram_bank_mmu_setup() to avoid access to bd->bi_dram
before relocation.
This patch allow to use the generic weak function dram_bank_mmu_setup
to activate the MMU and the data cache in SPL or in U-Boot before
relocation, when bd->bi_dram is not yet initialized.
In this cases, the MMU must be initialized explicitly with
mmu_set_region_dcache_behaviour function.

Move CONFIG_SYS_ARM_CACHE_WRITETHROUGH and

Kconfig uses a choice between the 3 values supported in U-Boot,
including the new configuration CONFIG_SYS_ARM_CACHE_WRITEBACK
(the default configuration).
The patch also avoids to select simultaneously 2 configurations.

Board files should not re-implement do_reset() to work around this
function not being defined in for specific configurations. Rather,
the fix is to compile in drivers which implement this properly.
This patch enables sysreset and watchdog drivers in SPL and ties
them together to implement the same as the do_reset() hack in the
board file, except correctly in the DM/DT framework.

If the cpu-idle-states is missing from the DT in the first place, do
not fail on removing in. Just move on and do not even print an error,
since not being able to remove something which is not there in the
first place is not an error and surely does not justify failing to
boot.
Turn the surrounding prints into debugs to reduce the useless noise.

after we clean WDA bit. But on mscale, the WDOG_B may be later than
internal reset, and cause PMIC not reset. As we enabled the SD3.0

The ROC-RK3328-CC from Firefly and Libre Computer Project is a credit
card size development board based on the Rockchip RK3328 SoC, with:
- 1/2/4 GB DDR4 DRAM
- eMMC connector for optional module
- micro SD card slot
- 1 x USB 3.0 host port
- 2 x USB 2.0 host port
- 1 x USB 2.0 OTG port
- HDMI video output
- TRRS connector with audio and composite video output
- gigabit Ethernet
- consumer IR receiver
- debug UART pins
The ROC-RK3328-CC has the enable pin of the SD card power switch tied
to GPIO_0_D6. This pin also has the function SDMMC0_PWREN, which is
muxed by default. SDMMC0_PWREN is an active high signal controlled by
the MMC controller, however the switch enable is active low, and
pulled low (enabled) by default to make things work on boot.
As such, we need to mux away from SDMMC0_PWREN and use GPIO to enable
power to the card. The default GPIO state for the pin is pull-down and
input, which doesn't require extra configuration when paired with the
external pull-down and active low switch.
Deal with this by enabling regulator support in SPL, and setting
"u-boot,dm-spl" for the regulator and other device nodes needed for
muxing the pin.
The device tree file is synced from the Linux kernel next-20200324.

- removal of deprecated RK_FUNC_* macros
- update of device tree binding headers
- new devices
- device tree cleanups
- gmac2phy disabled in -u-boot.dtsi as it is not supported in U-boot
This includes a re-ordering of the USB device nodes compared to upstream
Linux, moving the dwc2 OTG controller after the EHCI/OHCI nodes. This is
currently required as otherwise the dwc2 controller would not be able to
