Subject: config_fallbacks: Add a default entry for CONFIG_SYS_PBSIZE
X-Git-Tag: v2015.01-rc4~30^2~2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=31cc2c85dc38429e2558dbf1a42e18480e8e9ba6;p=u-boot

config_fallbacks: Add a default entry for CONFIG_SYS_PBSIZE

Entering the maximum number of characters defined by CONFIG_SYS_CBSIZE into
the console and hitting enter afterwards, causes a hang in the system because
CONFIG_SYS_PBSIZE is not capable of storing the characters of the error message:
"Unknown command '' - try 'help'".

Provide a default size for CONFIG_SYS_PBSIZE so that it can store the error
message and allows the error message to be printed correctly with no hang.
