commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor"
breaks u-boot commandline working with long commands
sending to the board.Since the above patch, you have to setup the fcr register.
For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.Detected this issue with automated tbot tests on am335x
based shc board.The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)Possible boards/plattforms with problems:

Add compatibility string for the Ingenic JZ4780 SoC, the necessary
UART enable bit into FCR and register shift. Neither are encoded
in the DTS coming from Linux, so we need to support it this way.Signed-off-by: Marek Vasut

reg-offset is the part of standard 8250 binding in the kernel.
It is shifting start of address space by reg-offset.
On Xilinx platform this offset is typically 0x1000.Signed-off-by: Michal Simek

This reverts commit d9a3bec682f9756621615f4306718a356a3230e3.
While this is a correct change to do long term it unfortunately breaks a
number of platforms that are using pdata and not named struct members so
they are getting all of their data after 'base' incorrect.Acked-by: Michal Simek

This option is used by some boards, so support it with driver model. This
is really ugly - we should rewrite this driver once all users are moved to
driver model.Signed-off-by: Simon Glass

It is inconvenient to have to use casts when specifying platform data. Also
it is not strictly correct, since we should use map_sysmem() to convert an
address to a pointer.Adjust the platform data to use an address.

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.Signed-off-by: Stefan Roese

Instead of special casing the different access patterns, use common
code with light macros sprinkled in to accomodate for the different
layouts of the register structure.Note that this also changes the types of the registers for the
"positively packed (>1)" cases. As the registers truly are unsigned
chars, this is surely the Right Thing, but it is a semantic change.
Note that for this case depending on the endianness on the bus, we may
see a change of behaviour.Signed-off-by: Detlev Zundel
