[U-Boot] [RFC 0/2] Add support for bootstrap stage and compressed U-Boot image

[luigi.mantellini at idf-hit.com]

From: Luigi 'Comio' Mantellini <luigi.mantellini at idf-hit.com>

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

  Add support for bootstrap stage to QEMU-MIPS board.
