Benjamin Valentin	90751bcec1	mtd: fix return in mtd_erase() ... If `.erase` is implemented we must return, not execute the fallback code path fixes #14988	2020-09-09 19:38:40 +02:00
Benjamin Valentin	9a4141880c	mtd: allow to use non-pagewise functions ... If the underlying driver implements 'plain' read/write/erase fucntions, don't convert them to pagewise functions and back. Just use the old direct functions.	2020-09-02 22:50:24 +02:00
Benjamin Valentin	4034f96169	mtd: add page addressed operations ... Currently read(), write() and erase() all use 32 bit addressing. This is a problem when writing to media > 4 GiB, e.g. SD cards. The current implementation would wrap around after 4 GiB and corrupt data. To avoid this, add functions to the MTD subsystem that allow for page-wise addressing. This is how most of the underling storage drivers and the file-systems above work anyway. In the future we should then deprecate the 32-bit functions if all drivers are converted.	2020-08-18 17:25:39 +02:00
