The data sheet says that the DIV field cannot change while the CLKGATE
bit is set or modified. So do it a little more carefully, by first
clearing the bit, waiting for that to appear, then setting the DIV
field.

The comment says to clear the bypass bit, but in fact it sets it, thus
selecting ref_xtal. And the next line of code does not set the divider
to 12, but to (the reset value of) 1.

I tried clearing a bit by writing to hw_clkctrl_gpmi_clr, then
busy-waiting for it to actually clear. My board hung. The data sheet
agrees, these registers do not have _set, _clr, _tog, so fix up the
definitions. git grep -E 'clkctrl_(gpmi|ssp[0-9])_' says that nobody
uses those non-existing ops registers.

In cases when the same SPL should run on boards with i.MX8MM, that
differ in DDR configuration, it is necessary to try different
parameters and check if the training done by the firmware suceeds or
not.
Therefore we return the DDR training/initialization success to the
upper layer in order to be able to retry with different settings if
necessary.

Currently imx-specific bootaux command doesn't support ELF format
firmware for Cortex-M4 core.
This patches introduces a PoC implementation of handling elf firmware
(load_elf_image_phdr() was copy-pasted from elf.c just for PoC).
ELF64 binaries isn't supported yet.
This has the advantage that the user does not need to know to which
address the binary has been linked to. However, in order to handle
and load the elf sections to the right address, we need to translate the
Cortex-M4 core memory addresses to primary/host CPU memory
addresses (Cortex A7/A9 cores).
This allows to boot firmwares from any location with just using
bootaux, e.g.:
> tftp ${loadaddr} hello_world.elf && bootaux ${loadaddr}
Similar translation table can be found in the Linux remoteproc
driver [1].

On K3 devices there are 2 conditions where R5F can deadlock:
1.When software is performing series of store operations to
cacheable write back/write allocate memory region and later
on software execute barrier operation (DSB or DMB). R5F may
hang at the barrier instruction.
2.When software is performing a mix of load and store operations
within a tight loop and store operations are all writing to
cacheable write back/write allocates memory regions, R5F may
hang at one of the load instruction.
To avoid the above two conditions disable linefill optimization
inside Cortex R5F which will make R5F to only issue up to 2 cache
line fills at any point of time.
