We have a similar problem with the storage driver, which needs a block of 256
KiB of contiguous memory.

I guess at least that one should be solveable. If the 256kb is only
internal flash access, it is should not be part of the storage driver
but of whatever else is used to drive this.

If we convert the FLASH part to a character device driver, the 256 KiB will be
internal to the character device driver.

Assuming the module gets loaded shortly after boot, you can still allocate
256kb practically always, using get_free_pages().

I'm afraid that assumption is usually false, as you only need to access the
FLASH when you want to change boot flags or update the boot loader.
