Subject: [PATCH 02/15] mxs: mxsboot: Move sdcard BCB header to 4 sectors
|
||
|
|
offset
|
||
|
|
|
||
|
|
The MX23 Boot ROM does blindly load from 2048 offset while the MX28
|
||
|
|
does parse the BCB header to known where to load the image from. We
|
||
|
|
move the BCB header to 4 sectors offset so same code can be used by
|
||
|
|
both SoCs avoiding code duplication.
|
||
|
|
|
||
|
|
This idea was given by Marek Vasut <marex@denx.de>
