Slim Bootloader provides serial port info in its HOB to support
both IO or MMIO serial ports, but it's controlled by SYS_NS16550_MEM32
or SYS_NS16550_PORT_MAPPED in U-Boot.
To support both serial port configurations dynamically at runtime,
Slim Bootloader serial driver leverages NS16550_DYNAMIC.

At present this driver uses an assortment of CONFIG options to control
how it accesses the hardware. This is painful for platforms that are
supposed to be controlled by a device tree or a previous-stage bootloader.
Add a new CONFIG option to enable fully dynamic configuration. This
controls register spacing, size, offset and endianness.

UniPhier SoC updates for v2020.04 (2nd)
Denali NAND driver changes:
- Set up more registers in denali-spl for SOCFPGA
- Make clocks optional
- Do not assert reset signals in the remove hook
- associate SPARE_AREA_SKIP_BYTES with DT compatible
- switch to UCLASS_MTD
UniPhier platform changes:
- fix a bug in dram_init()
- specify loadaddr for "source" command
If the "source" command is not given the address, it uses
CONFIG_SYS_LOAD_ADDR, which is compile-time determined.
Using the "loadaddr" environment variable is handier because it is
relocated according to the memory base when CONFIG_POSITION_INDEPENDENT
is enabled.

All rockchip platforms support TPL or SPL-based bootloader
in mainline with U-Boot proper as final stage. For each
stage we need to burn the image on to flash with respective
offsets.
This patch creates a single boot image component using
- binman, for arm32 rockchip platforms
- pad_cat, for arm64 rockchip platforms.
This would help users to get rid of burning different
boot stage images.
The new image called 'u-boot-rockchip.bin'
which can burn into flash like:
₹ sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
This would support all rockchip platforms, except rk3128
since it doesn't support for SPL yet.

Add bootcount support for Rockchip rk3399.
The bootcount value is preserved in PMU_SYS_REG0 register,
this would help to support redundent boot.
Once the redundant boot triggers, the altboot command
will look for extlinux-rollback.conf on particular
bootable partition which supposed to be a recovery
partition where redundant boot required.

Some drivers define their own speed enums and use their own constants for
speed. It makes sense to have a unified defition of the different speeds.
Since many controllers have to do different things for fast/high speed, it
is a good idea to have an enum for the mode.
Add these as well as an enum for the address mode.
