Subject: [U-Boot] difference between V_PROMPT and CONFIG_SYS_PROMPT?
Date: Thu, 19 Nov 2009 03:00:01 -0500 (EST) [thread overview]
Message-ID: <alpine.LFD.2.00.0911190255590.29408@localhost> (raw)
another beginner-level question, i'm sure, but what's the
distinction between V_PROMPT and CONFIG_SYS_PROMPT for customizing the
u-boot prompt?
based on the output from a straightforward grep, it appears that
every example of customizing the prompt has the form:
#define V_PROMPT "OMAP3_EVM # "
... snip ...
#define CONFIG_SYS_PROMPT V_PROMPT
as in, V_PROMPT is set, for no other reason than to subsequently set
CONFIG_SYS_PROMPT a few lines later, at which point V_PROMPT never
seems to be used again.
is this just a historical holdover? any reason why
CONFIG_SYS_PROMPT can't be set directly and V_PROMPT ignored/removed?
