Some instructions in the ARM ISA have multiple output registers, such
as ldrd/ldp (load pair), where two registers are loaded from memory,
but also ldr with indexing, where the memory base register is incremented
as well when the value is loaded to the destination register.
MMIO emulation under KVM is based on using the architecturally defined
syndrome information that is provided when an exception is taken to the
hypervisor. This syndrome information describes whether the instruction
that triggered the exception is a load or a store, what the faulting
address was, and which register was the destination register.
This syndrome information can only describe one destination register, and
when the trapping instruction is one with multiple outputs, KVM throws an
error like
kvm [615929]: Data abort outside memslots with no valid syndrome info
on the host and kills the QEMU process with the following error:

QEMU: Terminated
This means that, in order to run U-Boot in QEMU under KVM, we need to
avoid such instructions when accessing emulated devices. For the flash
in particular, which is a hybrid between a ROM (backed by a read-only
KVM memslot) when in array mode, and an emulated MMIO device (when in
write mode), we need to take care to only use instructions that KVM can
deal with when they trap.
So override the flash read accessors that are used when running on QEMU
under KVM. Note that the the 64-bit wide read and write accessors have
been omitted: they are never used when running under QEMU given that it
does not emulate CFI flash that supports it.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:

Note - debricking procedure of imx28 devices:
