* /proc/bootinfo has a strict format. Each line contains a name/value
* pair which are separated with a colon and a single space on both
* sides of the colon. The following defines help you size the
* buffers used to read the data from /proc/bootinfo.
*
* BOOTINFO_MAX_NAME_LEN: maximum size in bytes of a name in the
* bootinfo line. Don't forget to add space
* for the NUL if you need it.
* BOOTINFO_MAX_VAL_LEN: maximum size in bytes of a value in the
* bootinfo line. Don't forget to add space
* for the NUL if you need it.
* BOOTINFO_BUF_SIZE: size in bytes of buffer that is large enough
* to read a /proc/bootinfo line. The extra
* 3 is for the " : ". Don't forget to add
* space for the NUL and newline if you
* need them.
