The debug UART on modern machines uses a 32-bit wide transfer. Without
this, setting debug output causes a hang or no output. It is not obvious
(when enabling CONFIG_DEBUG_UART) that this is needed.
Enable 32-bit access to avoid this trap.

If coreboot does not set up sysinfo for the UART, SPL currently hangs.
Use the DBG2 technique there as well. This allows coreboot64 to boot from
coreboot even if the console info is missing from sysinfo

This driver is not actually built since a Kconfig was never created for
it.
Add a Kconfig (which is already implied by COREBOOT) and update the
implementation to avoid using unnecessary memory. Drop the #ifdef at the
top since we can rely on Kconfig to get that right.
To enable it (in addition to serial and video), use:
setenv stdout serial,vidconsole,cbmem

On x86 devices we use CAR (Cache-As-RAM) to hold the malloc() region in
SPL, since SDRAM is not set up yet. This means that driver model stores
its tables in this region.
When preparing to jump from SPL to U-Boot proper, we must disable CAR, so
that the CPU can uses the caches normally. This means that driver model
tables become inaccessible. From there until we jump to U-Boot proper, we
must avoid using driver model.
This is only a problem on boards which operate this way, for example
chromebook_link64
Add a flag to indicate that driver model is dead and should not be used.
It can be used in SPL to avoid hanging the machine.

When flash erase is called with size parameter, code is checking
if sectors are locked or not. But for checking, the whole device
length minus offset is used instead of actual size which should
be erased. That's why when only some sectors are locked it is
not possible to erase unlocked sectors.
The length is calculated as "length = max_chipsize - offset",
flash_is_unlocked() api is getting updated with length which is
incorrect. Fix this flash_is_unlocked() api by passing the size
parameter.
ZynqMP> sf erase 0 100000
len=0x8000000 which is flash size
size=0x100000
We need to update the size in the flash_is_unlocked() api and not
the length.
