aspeed: ast2500: Read clock ofdata in the correct method
At present the clock driver reads its ofdata in the probe() method. This
is not correct although it is often harmless.
However in this case it causes a problem, something like this:
- ast_get_scu() is called (from somewhere) to get the SCI address
- this probes the clock
- first sets up ofdata (which does nothing at present)
- DM marks clock device as active
- DM calls pinctrl
- pinctrl probes and calls ast_get_scu() in ast2500_pinctrl_probe()
- ast_get_scu() probes the clock, but sees it already marked as
probed
- ast_get_scu() accesses the clock's private data, with scu as NULL
- DM calls clock probe function ast2500_clk_probe() which reads scu
By putting the read of scu into the correct method, scu is read as part of
ofdata setup, and everything is OK.
Note: This problem did not matter until now since DM always probed all
parents before reading a child's ofdata. The fact that pinctrl is a child
of clock seems to trigger this strange bug.

console_codes(4) man page.
If the bootefi command is called without passing the address of a device
tree, the internal device tree is used. For devices with a hardware device
tree it is preferable to used the hardware device tree in this case.
As part of moving the parsing of command line arguments to do_bootefi()
call efi_install_fdt() with the address of the device tree instead of a
string.
If the address is EFI_FDT_USE_INTERNAL (= 0), the internal device tree
is used.
When the GetInfo() method of the EFI_FILE_PROTOCOL is called to retrieve
the file system info we claim that the volume is read only and has no free
space. This leads to failures in programs that check this information
before writing to the volume like SCT's InstallSct.efi.
Currently there is no function to determine these parameters in U-Boot. So

spl: fit: Allow the board to tell if more images must be loaded from FIT
spl_fit_get_image_name() is used to get the names of the images that the
SPL must load from the FIT. It relies on the content of a property present
in the FIT. The list of images is thus statically defined in the FIT.
With this scheme, it quickly becomes hard to manage combinations of more
than a handful of images.
To address this problem, give the board driver code the opportunity to
add to the list of images. The images from the FIT property are loaded
first, and then the board_get_fit_loadable() is called to get more image
names.
This function will be used by the SPL to get the names of images to load
from the FIT. This allows to load different images based on runtime HW
detection.

spl: fit: be more verbose when an error occurs when applying the overlays
There are many ways the overlay application can fail.
2 of them are probably the most common:
- the application itself failed. Usually this is comes from an unresolved
reference
- DTBO not available in FIT (could be because of a typo)
In both case it is good to be more explicit about the error and at least
show which overlay is failing.
spl: fit: Do not fail immediately if an overlay is not available
If one overlay that must be applied cannot be found in the FIT, the current
implementation stops applying the overlays. Let's make it skip only the
failing overlay instead.
spl: fit: allocate a temporary buffer to load the overlays
If the node describing an overlay does not specify a load address, it will
be loaded at the address previously used.
Fixing it by allocating a temporary buffer that will be used as a
default load address. By default, the size of the buffer is 64kB which
should be plenty for most use cases.
spl: fit: Make room in the FDT before applying overlays
Make room in the FDT before applying the overlay, otherwise it may fail if
the overlay is big. As the exact added size is not known in advance, just
add the size of the overlay.
Move after the end of the application of the overlays, the resize of the
FDT for the injection of the details on the loadables.
