%package mkimage
Summary:	Generate kernel image for U-Boot
Summary(pl.UTF-8):	Generowanie obrazu jądra dla U-Boota
Group:		Applications/System

%description mkimage
This package contains the mkimage utility, which encapsulates a
compressed "uImage" Linux kernel image with header information, CRC32
checksum, etc., for use with the U-Boot bootloader.

mkimage can also be used to create ramdisk images for use with U-Boot,
either separated from the Linux kernel image, or combined into one
file. mkimage encapsulates the images with a 64 byte header containing
information about target architecture, operating system, image type,
compression method, entry points, time stamp, CRC32 checksums, etc.

%description mkimage -l pl.UTF-8
Ten pakiet zawiera narzędzie mkimage, łączące skompresowany obraz
jądra Linuksa "uImage" w nagłówkiem, sumą kontrolną CRC32 itp. do
wykorzystania przez bootloader U-Boot.

mkimage może być używane także do tworzenia obrazów ramdysków do
wykorzystania przez U-Boota - osobnych w stosunku do obrazu jądra lub
połączonych w jeden plik. mkimage obudowuje obrazy w 64-bajtowy
nagłówek zawierający informacje o architekturze docelowej, systemie
operacyjnym, rodzaju obrazu, metodzie kompresji, punktach wejściowych,
czasie utworzenia, sumach kontrolnych CRC32 itp.
