[U-Boot] [PATCH v2 0/6] Introducing the Broadcom bcm281xx Architecture
by Darwin Rambo 04 Feb '14

04 Feb '14

This patchset introduces the Broadcom bcm281xx family of mobile SoC chips. Broadcom kona hardware blocks are often found in Broadcom mobile SoC chips including the bcm281xx family, so support for some of these kona blocks is also provided here. These patches work on u-boot master as well as the u-boot-arm custodian tree. v2 changes ---------- Delete lowlevel_init.S and create s_init.c. File header cleanup, cosmetic changes, dead code removal. Create include/bitfield.h. Use get_ram_size(). Use weak timer_init(); Skip lowlevel init. Remove memory test config. Use standard baud table and prompt.

[U-Boot] Internal Boot mode
by JYOTI DUBEY 04 Feb '14

04 Feb '14

Can anybody tell what all happens inside an i.mx6 board when we try to boot it in internal mode? Is it that in internal mode the board does not look into the flash at all to discover the u-boot image and the image must be provided only from the serial port? If yes then what steps should be followed to perform internal booting? It would be of great help if commands for performing internal booting is provided. Thanks in Advance!
