As U-Boot actually does not use floating point at all this should not
make a significant difference for the produced binaries.

The default load addresses for the various payloads (kernel, DT,
ramdisk) on systems with just 32MB of DRAM have some issues:
For a start the preceding comment doesn't match the actual values:
apparently they were copied from the 64MB S3 layout, then halved, but
since 0x5 is NOT the half of 0x10, they don't match up.
Also those projected maximum sizes are quite restrictive: it's not easy
to build a compressed kernel image with just 4MB. The only defconfig in
mainline Linux that supports the F1C100s (the only 32MB user so far)
creates a 6MB compressed / 15MB uncompressed kernel.
Rearrange the default load addresses to accommodate such a kernel: we
allow an 7MB/16MB kernel, and up to 5MB of ramdisk, stuffing the smaller
binaries like the DTB towards the end, just before the relocated U-Boot.
Shrink the size for DTB and scripts on the way, there is no need for
allowing up to 512K for them.

Traditionally we assumed that every Allwinner board would come with at
least 256 MB of DRAM, and set our DRAM layout accordingly. This affected
both the default load addresses, but also U-Boot's own address
expectations (like being loaded at 160 MB).
Some SoCs come with co-packaged DRAM, but only provide 32 or 64MB. So
far we special-cased those *chips*, as there was only one chip per DRAM
size. However new chips force us to take a more general approach.
Introduce a Kconfig symbol, which provides the minimum DRAM size of the
board. If nothing else is specified, we use 256 MB, and default to
smaller values for those co-packaged SoCs.
Then select the different DRAM maps according to this new symbol, so
that different SoCs with the same DRAM size can share those definitions.
Inspired by an idea from Icenowy.
This is just refactoring: compiled for all boards before and after this

Chances are when one boots U-Boot proper from a given storage medium,

No fallback mechanism is provided as to not dirty other storage medium

The original code set up the DDR clock to 48 MHz, not 50MHz as

Notes in RK3399 TRM [1]. 2.9.2.B says:
PLL frequency range requirement
[...]
FOUTVCO: 800MHz to 3.2GHz
2.9.2.A :
PLL output frequency configuration
[...]
FOUTVCO = FREF / REFDIV * FBDIV
FOUTPOSTDIV = FOUTVCO / POSTDIV1 / POSTDIV2
FREF = 24 MHz
The original code gives FOUTVCO: 24MHz/1 * 12 = 288MHz < 800MHz
And the resulting FOUTPOSTDIV is 288MHz / 3 / 2 = 48MHz
but the requested frequency was 50MHz
Note:
2.7.2 Detail Register Description
PMUCRU_PPLL_CON0 says
fbdiv
Feedback Divide Value
Valid divider settings are:
[16, 3200] in integer mode
So .fbdiv = 12 wouldn't be right. But 2.9.2.C says:
PLL setting consideration
[...]
The following settings are valid for FBDIV:
DSMPD=1 (Integer Mode):
12,13,14,16-4095 (practical value is limited to 3200, 2400, or 1600
(FVCOMAX / FREFMIN))
[...]
So .fbdiv = 12 would be right.
In any case FOUTVCO is still wrong. I thank YouMin Chen for
confirmation and explanation.
Despite documentation, I don't seem to be able to reproduce a
practical problem with the wrong FOUTVCO. When I initially found it I
thought some problems with detecting the RAM capacity in my Rock Pi 4B
could be related to it and my patch seemed to help. But since I'm no
longer able to reproduce the issue, it works with or without this
patch. And meanwhile a patch[2] by Lee Jones and YouMin Chen addresses
this issue. Btw, shouldn't that be commited?
So this patches solves no visible problem. Yet, to prevent future
problems, I think it'd be best to stick to spec.
An alternative to this patch could be
{.refdiv = 1, .fbdiv = 75, .postdiv1 = 6, .postdiv2 = 6};
This would theoretically consume more power and yield less jitter,
according to 2.9.2.C :
PLL setting consideration
[...]
For lowest power operation, the minimum VCO and FREF frequencies
should be used. For minimum jitter operation, the highest VCO and
FREF frequencies should be used.
[...]
But I haven't tried it because I don't think it matters much. 50MHz
for DDR is only shortly used by TPL at RAM init. Normal operation is
at 800MHz. Maybe it's better to use less power until later when more
complex software can control batteries or charging or whatever ?
