Marek Behún [Tue, 5 Oct 2021 13:56:06 +0000 (15:56 +0200)]
mtd: Remove mtd_erase_callback() entirely

The original purpose of mtd_erase_callback() in Linux at the time it was
imported to U-Boot, was to inform the caller that erasing is done (since
it was an asynchronous operation).

All supplied callback methods in U-Boot do nothing, but the
mtd_erase_callback() function was (until previous patch) grossly abused
in U-Boot's mtdpart implementation for completely different purpose.

Since we got rid of the abusement, remove the mtd_erase_callback()
function and the .callback member from struct erase_info entirely, in
order to avoid such problems in the future.

mtd: mtdpart: Make mtdpart's _erase method sane

The _erase() method of the mtdpart driver, part_erase(), currently
implements offset shifting (for given mtdpart partition) in a weird way:
  1. part_erase() adds partition offset to block address
  2. parent driver's _erase() method is called
  3. parent driver's _erase() method calls mtd_erase_callback()
  4. mtd_erase_callback() subtracts partition offset from block address
     so that the callback function is given correct address
The problem here is that if the parent's driver does not call
mtd_erase_callback() in some scenario (this was recently a case for
spi_nor_erase(), which did not call mtd_erase_callback() at all), the
offset is not shifted back.

Moreover the code would be more readable if part_erase() not only added
partition offset before calling parent's _erase(), but also subtracted
it back afterwards. Currently the mtd_erase_callback() is expected to do
this subtracting since it does have to do it anyway.

Add the more steps to this procedure:
  5. mtd_erase_callback() adds partition offset to block address so that
     it returns the the erase_info structure members as it received them
  6. part_erase() subtracts partition offset from block address

This makes the code more logical and also prevents errors in case
parent's driver does not call mtd_erase_callback() for some reason.

(BTW, the purpose of mtd_erase_callback() in Linux is to inform the
 caller that it is done, since in Linux erasing is done asynchronously.
 We are abusing the purpose of mtd_erase_callback() in U-Boot for
 completely different purpose. The callback function itself has empty
 implementation in all cases in U-Boot.)

This results in partition offset being added prior calling

the `mtd erase` command does not erase the whole partition, only some of
it's blocks:

When using a file to store UEFI variables we must make sure that secure
boot related variables are not loaded from this file. With commit
9ef82e29478c ("efi_loader: don't load signature database from file")
this has already been implemented for variables defined in the UEFI
specification. As most Linux distributions use Shim we should do the same
for Shim's MOK database.
