Hi Marek,

Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base
address. Convert all board configurations to this new macro. This is
the
first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a
clean up, no functional change.
The new macro contains compile-time test to verify N is in suitable
range. The test works such that it multiplies constant N by constant
double-negation of size of a non-empty structure, i.e. it multiplies
constant N by constant 1 in each successful compilation case.
The non-empty structure may contain C11 _Static_assert(), make use of
this and place the kernel variant of static assert in there, so that
it performs the compile-time check for N in the correct range. Note
that it is not possible to directly use static_assert in compound
statements, hence this convoluted construct.

I have not found the reason, but this breaks MX51:
All this UART_BASE_ADDR stuff is postponed, just drop for now.
Ok, understood - I remove them.
Well, there is at least one patch depending on this:
http://patchwork.ozlabs.org/project/uboot/patch/20220505074341.24086-2-peng....@oss.nxp.com/
I will first try just to remove the i.MX5 patch, it seems to me that the
MX51 is the only architecture that cannot be built.

Stefano
Best regards,
