From ea2453d56b8860dbd18a3c517531ffc8dcb5c839 Mon Sep 17 00:00:00 2001 From: Pantelis Antoniou Date: Thu, 14 Mar 2013 05:32:48 +0000 Subject: dfu: Support larger than memory transfers. Previously we didn't support upload/download larger than available memory. This is pretty bad when you have to update your root filesystem for example. This patch removes that limitation (and the crashes when you transfered any file larger than 4MB) by making raw image writes be done in chunks and making file maximum size be configurable. The sequence number is a 16 bit counter; make sure we handle rollover correctly. This fixes the wrong transfers for large (> 256MB) images. Also utilize a variable to handle initialization, so that we don't rely on just the counter sent by the host.

We also make them take an loff_t limit on how much data can be read or written. This means that we can now catch the case of when writing to a partition would exceed the partition size due to bad blocks. To do this we also need to make check_skip_len count not just complete blocks used but partial ones as well. All callers of nand_(read|write)_skip_bad are adjusted to call these with the most sensible limits available. The changes were started by Pantelis and finished by Tom.
