Flag status register polling is required for micron 512Mb flash

There is no other call other than spi_flash_cmd_wait_ready(),

Now the two memories were linearly accessable without

when memory change happen.
- driver -> on LQSPI_CFG, Enable TWO_MEM[BIT:30] on LQSPI_CFG
Enable U_PAGE[BIT:28] if U_PAGE flag set - upper memory

Updated the xilinx qspi dual parallel flash access support
to use 3-byte addressing instead of 4-byte addressing used

Instead of sending 4-byte addressing from mtd layer and
then the controller will again divide the offset addr by 2 and
convert the 4-byte address into 3-byte address, With this
new logic the mtd will serve the offset as offset by 2 and
send the 3-byte addressing to controller driver, as the

dual parallel functionality.

Currently, u-boot end up in infinite loop when the status reg of the SPI flash

We introduce a counter. If the status register value is still not 0 after 1000

Remove ARM eabi exception handling tables (for frame unwinding).
AFAICT, u-boot stubs away the frame unwiding routines, so the tables will
more or less just consume space. It should be OK to remove them.
Comment from Albert:
By default the *exidx* sections are between rodata and data, so
removing them causes many apparent changes at the binary level.
However, builds of zynq based on ARM master with the patch above vs
master with a patch mapping *exidx* sections after BSS gives identical
binaries. Thus the RFC has no functional effect.
Also, ARM EHABI states that [exception] Tables are not required for ABI
compliance at the C/Assembler level but are required for C++.
So as long as we don't put any C++ code in U-Boot (a prospect that I
don't see happening any time soon), this RFC is safe and either is a
no-op or removes useless bytes from the binary.

fdt: Ensure that libfdt_env.h comes from U-Boot
When building host utilities, we include libfdt.h from the host, not from
U-Boot. This in turn brings in libfdt_env.h from the host, which can mess
up the types and cause a build failure, depending on the host environment.
To fix this, force inclusion of U-Boot's libfdt_env.h so that the types
are correct.
Another way to fix this is to use -nostdinc and -idirafter to ensure that
system includes are included after U-Boot ones. Unfortunately this means
that U-Boot's errno.h gets included instead of the system one. This in
turn requires a hack to errno.h to redirect things, so all in all the
solution in this patch is probably cleaner.
