Hi All,
The following adds barebox-update command support. This command is
supposed to provide a dedicated command for updating barebox.
The rationale behind this is:
- We can add additional generic, SoC specific, board specific sanity
checks (Is this really a barebox image? Does the image fit into the
device?)
- Sometimes SoC or board specific fixups are necessary. For example,
with Omap Nand boot we have to switch the Nand driver into a different
ECC mode before flashing barebox. With i.MX MMC card boot we want
to preserve the partition table. On i.MX28 Nand boot we have to create
a Boot Control Block. The list does not end here...
The current idea is:
A board can register one or multiple update handlers. The update handlers
themselves are registered by a board because only the board knows where
it actually can boot from. Nevertheless there might be generic handlers
available, the most simple one being: Check image header, check size, write
to device.
This is in an early state, right now there are only dummy handlers, hence the
RFC state.
