Patrick Delaunay 562274730a dfu: mtd: skip empty pages when writing page for UBI partition ... Align the DFU MTD backend for the UBI partitions with the mtd command write behavior when the option .dontskipff is not used: don't write the empty pages (full of 0xFF); it is not required for UBI, see [1] for details. This patch avoids the "free space fixup" procedure in the kernel [2] and allows to program a UBIFS volume generated by mkfs.ubifs without the option -F, --space-fixup. The MTD DFU backend implements this behavior introduced on DFU NAND backend by the commit 13cb7cc9e8 ("dfu: Add option to skip empty pages when flashing UBI images to NAND") and also supported by the command nand by CONFIG_CMD_NAND_TRIMFFS and by commit c9494866df ("cmd_nand: add nand write.trimffs command").
