I was running into this limit with a not overly long PXE append line.

Since the PXE code wants to print the resulting command line increase
CONFIG_SYS_PBSIZE too.

v2: Apply to exynos generally since consolidation.

What if we add a default definition like this:

#define CONFIG_SYS_CBSIZE              1024    /* Console I/O Buffer Size */
#define CONFIG_SYS_PBSIZE              1024    /* Print Buffer Size */

,then if CONFIG_SYS_CBSIZE and CONFIG_SYS_PBSIZE are not defined in
the board file, we just use the default?

I had the same issue sometime ago and I am wondering if this could be
a better way to handle it.
