Add reverse engineered code to add support for DDR3 DRAM chips on the
Allwinner A523 DRAM controller.
The timings are copying what boot0 set up on the X96QPro+ TV box, though
they seem quite suboptimal, with longer latencies that would be required
for DDR3-1600. The chips are also actually capable of DDR3-1833, so
there is room for future improvement.

DRAM init code, as per reverse engineering and matching against
previous SoCs. As usual no real documentation, and the DRAM controller
is the usual mixture of close-to-previous IP and new inventions.
This version supports LPDDR4 for now only, as seen on the early boards.
This needs improvements, but it can be done later.

This adds the early A523 clock setup code, for the basic peripheral PLL
and the basic bus clocks (APB/AHB). This is quite close to the existing
H6 and H616 clock code, so this shares the same file. A few bits and bobs
are different, though, so filter for the A523 in a few occasions.

The cpu_sunxi_ncat2.h header file contains addresses of some peripherals
that are needed for the SPL, for chips that belong to the "NCAT2"
generation.
The Allwinner A523 is a member of this group, but a few addresses
differ, and we need a few more addresses, for playing with the core
reset, for instance.
Add the new addresses needed for the A523 and guard existing definitions
that conflict with that new chip.

The Allwinner A523 SoC has a slightly changed mod clock, where the P
factor, formerly a shift value, is now a second divider value.
Also the input clock is not PLL_PERIPH0 (600MHz) anymore, but
PLL_PERIPH0_400M (for MMC0/1), so adjust the input rate calculation
accordingly. MMC2 has a different set of parents, so the input clock
is 800 MHz there.
Adjust for all of this.

The watchdog in the Allwinner A523 SoC differs a bit from the one in the
previous SoCs: it lives in a separate register frame, so no longer
inside some timer device, and it manages to shuffle around some
registers a bit. But it also conveniently adds a direct reset
functionality, so we don't need to use a dummy timeout period.
Avoid introducing a new MMIO register frame C struct, but just define
the one needed register offset as a macro. Then just trigger this new
direct reset functionality in the A523 specific reset_cpu()
implementation.

The Allwinner A523 features 8 CPU cores, organised in two clusters, both
driven by separate PLLs. Also there is the DSU PLL, which clocks the
hardware that connects the cores to the rest of the system.
And while the PLL registers itself are very similar, they are located in
a separate register frame, outside the main CCU, and also the register
controlling the CPU clock source (mux) is different.
Provide a separate function that reparents the two clusters and the DSU,
while their PLLs are programmed. For the actual PLL programming, we rely
on the existing shared routine.
The selection between the new A523 routine and the existing code is made
with C if statements, but since the choice is effectively made at compile
time already, the compiler optimises away the other code paths, leaving
just the one required function in.

When we program the CPU PLL, we need to switch the CPU clock source away
from the PLL temporarily, then switch it back, once the PLL has
stabilised.
The CPU CLK register will be different on the A523, so move the current
code into a separate function, to allow using a different version of
that later for the A523.

The SPL initial clock setup code for the Allwinner H6 and H616 SoCs uses
a simple CPU PLL setup routine, which programs all register bits at once,
then waits for the LOCK bit to clear.
The manual suggests to follow a certain procedure for bringing up any
PLLs, which involves several register writes, one at a time, and some
delays. Also the H616 and the new A523 require some tiny changes in this
sequence, and the different SoCs also feature some extra bits here and
there, which we should not just clear.
So factor out the PLL setup routine, and make it follow the manual's
suggestion. This will read the PLL register at the beginning, then tweak
the bits we need to manipulate, and writes the register several times on
the way. This allows to cover the specific bits for different SoCs.
Besides improving the reliability of the PLL setup, this helps with the
A523, which requires *three* CPU PLLs to be programmed.

The Allwinner PLLs share most of their control bits, they differ mostly
in the factors and dividers.
Drop the PLL specific definition of those common bits, and use one
shared macro, for all PLLs.
This requires changing the users in the SPL clock and DRAM code.

u-boot.bin capsule4.bin

- Fastboot (including flashing to eMMC boot partitions)
As all Exynos firmware binaries (including U-Boot) are contained in eMMC

Add 'dfu_alt_info' environment variable which contains:
- Linux eMMC partitions ('esp' and 'rootfs')
- eMMC Boot Partition A layout, where all the firmware reside
It makes it possible to update the bootloader (U-Boot). All sizes in
'dfu_alt_info' are given in 512B blocks (LBA). eMMC size is 58.2 GiB.
The eMMC Boot Partition A (mmc0boot0) layout looks like this:
boot0 partition (4 MiB)
0x0 +----------------------------------+
| fwbl1 (12 KiB) |
0x18 +----------------------------------+
| epbl (76 KiB) |
0xb0 +----------------------------------+
| bl2 (256 KiB) |
0x2b0 +----------------------------------+
| dram_train (16 KiB) |
0x2d0 +----------------------------------+
| ect_test (50 KiB) |
0x334 +----------------------------------+
| acpm_test (130 KiB) |
0x438 +----------------------------------+
| bootloader (2 MiB) |
0x1438 +----------------------------------+
| el3_mon (256 KiB) |
0x1638 +----------------------------------+
where U-Boot should be flashed into 'bootloader' partition. So U-Boot
binary size should be 2 MiB or less. The whole boot0 partition is 4 MiB,
but only 2.8 MiB is currently used.
With this change, the U-Boot binary can be updated on eMMC like this:
=> dfu 0 mmc 0
$ dfu-util -D u-boot.bin -a bootloader
Looking at E850-96 booting diagram at [1,2], it's easy to see how these
binaries are being executed in the same order they are placed in
mmc0boot0 area. E.g. fwbl1 is definitely BL1 (software part of Boot
ROM). So it's obvious the ROM code just reads the binary from eMMC at
0x0 offset into RAM (SRAM?) and executes it.
All mentioned images can be found at [3], as stated in E850-96 U-Boot
documentation. 'dram_train', 'ect_test' and 'acpm_test' areas should be
ignored -- they are not flashed with real images.
