sunxi: support loading with SPL > 32KB
H616 supports and needs bigger SPL than 32 KiB, mostly due to big DRAM
driver and need for PMIC configuration, which pulls several drivers which
are not needed otherwise.
spl_mmc_get_uboot_raw_sector() will now compare pre-configured size with
that, reported in SPL header. If size in header is bigger, it will use
that value instead.
In the process of function rework, also add missing function argument.

also always added a half a second delay to wait for a SATA disk to power

Fix this by properly comparing the Kconfig symbols against the empty

doc: FIT image: Clarify format and simplify syntax
** Introduction
There are currently four ways to load an OS image with u-boot
1. SPL -> u-boot -> bootm
2. SPL blue falcon mode
3. "Basic" FIT image (CONFIG_LOAD_FIT)
4. "Full-featured" FIT image (CONFIG_LOAD_FIT_FULL)
These four code paths were developed independently, and share very
little code. (3) and (4), behave very differently, are littered with
special cases. They even have different DTS syntax and properties.
The cause of this divergence is that the FIT format specification
leaves a number of things open to interpretation. The purpose of this
change is to enable the reduction of code size, duplication, and
complexity by updating and streamlining the FIT format.
We are only marginally concerned with backwards compatibility, because
we don't have inter-compatibility. For example, CONFIG_LOAD_FIT is
able to load images that CONFIG_LOAD_FIT_FULL won't. This is a direct
result of the incompatible syntax between the two implementations.
Ideally, these changes would enable "simple" FIT to be a subset of the
"full" fit implementation, and share most code. These changes should
also eliminate the need for falcon mode (although we are not
advocating for the removal of falcon mode at this time).
** Description of changes
* The "configurations" node is now mandatory
Guessing how to load components based on their "os" and "type" invites
confusion and superfluous heuristics. Instead, require each FIT image
to be explicit on how components should be loaded.
* Eliminate "ramdisk", "setup", "standalone", and "fpga" properties
Having too many special purpose properties requires special-casing
FIT loading code. When a special property can be handled by another
property, it is redundant.
- A "ramdisk" is identical to a loadable. Thus ramdisk images should
be placed under "loadables".
- A "setup" node can be achieved by using a "kernel" or "firmware"
property instead.
- "standalone" is used for u-boot nodes. The correct property to use
in this case is "firmware".
- "fpga" is a loadable
* Prioritize control between "firmware" and "kernel"
"firmware" and "kernel" are special nodes in that control is passed
to the "entry-point" of the image. Both can be present, for example,
an OP-TEE firmware with a linux kernel. When both are present,
control is passed to the "firmware" image.
** Further generalizations (not included herein)
The "firmware" and "kernel" properties could be generalized as a
"next-boot-stage", or similar name. This "next" stage would be special
in that it is both executable, and is the stage that is passed
control. For example, "next-stage" could be an op-tee image, with
linux as a loadable, or a u-boot image.
