Hi All,
The following patches introduce the bootstrap support that enable to have a
compressed U-Boot image.
The bootstrap code supports the uncompressed as well as compressed payloads,
using LZMA, GZIP, BZIP2 and LZO.
Actually I developed just the mips version (using qemu-mips board)...
Please see the Patch #1 for the required defines to enable the required
features.
Of course, any suggestion is welcome.
ciao
luigi
Luigi 'Comio' Mantellini (2):
Add support for bootstrap stage that allows to have a compressed
U-Boot image. The final image will named "u-boot-bootstrap".
Add support for bootstrap stage to QEMU-MIPS board.
