Subject: [PATCH] lib: consistency of compress formats for kernel image

From: Haesung Kim <matia.kim@....com>

Magic number of compress formats for kernel image is defined by two bytes.
These numbers are written in hexadecimal number, nevertheless magic number
for 
only gunzip is written in octal number. The formats should be consistent for

readability. Therefore, magic numbers for gunzip are also defined by
hexadecimal
number.
