When Rockchip TPL blob is used, the memory areas that can be used for
DRAM is gotten from ATAGS passed through the DRAM at a specific address.
The DDR_MEM tag contains at most 10 areas, so we should default to 10 if
Rockchip TPL blob is used. Note that it is technically possible we need
more if one of those 10 areas overlaps with reserved memory area,
forcing us to split it in two. But a default doesn't need to handle all
cases, only most.

Allow RK3568 and RK3588 based boards to get the RAM bank configuration
from the ROCKCHIP_TPL stage instead of the current logic. This fixes
both an issue where 256MB of RAM is blocked for devices with >= 4GB
of RAM and where memory holes need to be defined for devices with
more than 16GB of RAM. In the event that neither SoC is used or the
ROCKCHIP_TPL stage is not used, fall back to existing logic.
The logic handles creating memory holes from reserved memory areas
defined in mem_map data struct in SoC C files, but only if the DRAM area
overlaps with one reserved memory area.
Since mem_map data struct is used, it should be rather straightforward
to add support for other SoCs if needed.
The logic is taken from Rockchip's U-Boot tag linux-5.10-gen-rkr4.1
(e08e32143dd).
Note that Rockchip's U-Boot/TF-A/OP-TEE modify the ATAGS at runtime as
well, but the DDR_MEM tag seems to be pretty much stable (though BL31
seems to be reserving only 1MB for itself at the moment).
u32 for ATAGS is used because it simplifies the pointer arithmetic and
it's expected that ATAGS are always below the 4GB limit allowed by u32.

Some variants of the ROCK Pi 4 series have an SPI flash chip populated
which can be booted from. This patch enables support in U-Boot for
building the image for the SPI flash, support for booting U-Boot from the
SPI flash chip and support in U-Boot for accessing the SPI flash using
`sf` commands.
Not all variants (e.g. ROCK Pi 4B, ROCK 4 Model C Plus, ROCK 4SE) come
populated with an SPI flash chip, but have the footprint on the board so
a user could solder their own to the board. With this patchset applied,
these board variants without an SPI flash chip still boot from MMC.
I have enabled support for both Winbond and XTX SPI flash devices since
different hardware variants have different devices populated:
- `rockpi4_v13_sch_20181112.pdf` contains a Winbond part `W25Q64FWZPIG`
- `rockpi4_v14_sch_20210114.pdf` contains an XTX part `XT25F32BWOIGT`
The ROCK Pi 4 I have is marked as "ROCK PI 4 v1.48" and contains an SPI
flash chip from XTX:
=> sf probe
SF: Detected xt25f32 with page size 256 Bytes, erase size 4 KiB, total 4 MiB
In the interest of supporting all board variants and not regressing
existing users who boot from MMC, I have enabled support for booting from
both SPI flash chip variants in the defconfig and left the environment
storage location as MMC to not break existing users who have the
environment stored on MMC.

Rockchip BROM writes a boot source id at CFG_IRAM_BASE + 0x10, this id
indicates from what storage media TPL/SPL was loaded from.
SPL uses this id to determine what device "same-as-spl" represent when
determining from where FIT should be loaded. This works as long as the
boot_devices array contain a matching id <-> node path entry.
However, SPL typically load a small part of TF-A into SRAM and on RK3399
this overwrites the CFG_IRAM_BASE + 0x10 addr used for boot source id.
For affected devices the u-boot,spl-boot-device would not be set when
booting from SPI flash and the flash@0 node was not explicitly listed
in the u-boot,spl-boot-order prop.
Here boot source id is 3 before FIT images is loaded, and 0 after:
