[U-Boot] [PATCH] include/ns16550.h: Unify structure declaration for registers

[Detlev Zundel]

Hello Shinya,

I just checked again - the "problematic" cases can only be REG_SIZE 2
and 4:

[dzu at pollux u-boot-testing (master)]$ grep CONFIG_SYS_NS16550_REG_SIZE include/configs/* | grep -v 'REG_SIZE.*\(1\|(-4)\|-4\|-8\)'
include/configs/AP1000.h:#define CONFIG_SYS_NS16550_REG_SIZE    4
include/configs/CU824.h:#define CONFIG_SYS_NS16550_REG_SIZE     4
include/configs/mcc200.h:#define CONFIG_SYS_NS16550_REG_SIZE    4
include/configs/ppmc7xx.h: * CONFIG_SYS_NS16550_REG_SIZE - 64-bit accesses to 8-bit port
include/configs/xilinx-ppc.h:#define CONFIG_SYS_NS16550_REG_SIZE 4

CU824 incidentally is the platform that I tested the patch on (PowerPC),
ppmc7xx is a false positive, so only three platforms remain.  I'm almost
100% sure that mcc200 also works, as it is also a PowerPC platform
comparable to CU824. Is AP1000 your platform?

We should really work to get these platforms in order, the fallout is
not as big as may have been expected...

Cheers
  Detlev
