/* This API is for the bootloader recovery menu and Rockbox utility to handle
|
|
* bootloader installation, backup, and restore.
|
|
*
|
|
* Currently the installer can only handle NAND flash, although the X1000 can
|
|
* boot from NOR flash or SD/MMC. Support for other storage media can be added
|
|
* when there is a target that needs it.
|
|
*
|
|
* Bootloader updates are tarballs, and they can "monkey patch" the flash in
|
|
* a customizable way (but fixed at compile time).
|
|
*
|
|
* Backup and restore simply takes the range of eraseblocks touched by the
|
|
* monkey patch and copies them to or from a regular file.
