Hello. I'm happy to announce a new u-boot clone - I've named it mboot. Please visit https://github.com/ierton/mboot. To see an example of board's initialisation routine, visit [1].

MBOOT bootloader ================

MBOOT is a clone of well known das U-Boot, with reduced functionality. I think, it is it's main benefit. The key point is:

Allow the board owner to write a code he needs to boot the board.

This means that there is no single board_init_r function for everyone with tones of defines, callbacks, switches and bugs people are afraid to fix because they think it can hurt someone else. Sorry for my English, there are probably some grammar mistakes.

Other features:

* All board's boot procedure is in single file (actually, only one board is supported - the one I have access to). See board/uemd/uemd.c for an illustration. * Smaller and cleaner Makefile. No symlinks, almost no generated files, still supporting linux-style CONFIG_ defines. Works faster! * Cleaner code: Network stack and Main loop now have explicit states, main booting procedure is in single board-specific file, lighter environment system. * New MTD stack and read-write routines. * Easy framework for in-place generating of Linux tags and commad line. * No relocation, easy to debug.

Working commands are: help, setenv, getenv, saveenv, reset, bootm, mtdboot, tftpboot, ping, version, mtd, fwupgrade and some other which are not so important.

Unfortunately, there are heavy limitations, U-boot is a huge project after all.

* Only Linux kernels, only legacy uImage format, no compression, no RAM disks (but it can be added easily) * One arch (ARM 1176), one board [1] (unknown for the public).
