mtd: OneNAND: Fix onenand_block_markbad

2017-06-23T14:38:07Z

commit dfe64e2c89731a3f9950d7acd8681b68df2bae03 Author: Sergey Lapin Date: Mon Jan 14 03:46:50 2013 +0000 mtd: resync with Linux-3.7.1 modified onenand_block_markbad to call mtd_block_markbad, but as _block_markbad function pointer used by mtd_block_markbad to do actual job is by default pointing back to onenand_block_markbad there is no way this function ever finishes its job. Fix it by changing function body according current (4.12-rc6) linux implementation. Tested on IGEPv2 board with Muxed OneNAND(DDP) 512MB containing several unerasable blocks this function marked bad.

onenand_spl_simple: Add DDP OneNAND support

2017-06-23T14:38:07Z

Current implementation is unable to access second half of DDP OneNAND flash (reads first half mirrored). Use block and bufferram address calculations from onenand_base to fix this. Signed-off-by: Ladislav Michl

onenand_spl_simple: Call onenand_spl_get_geometry() only once

2017-06-23T14:38:06Z

Do not call onenand_spl_get_geometry() for each block read. Signed-off-by: Ladislav Michl

treewide: replace #include with

Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap ) Replace all include directives for with . Signed-off-by: Masahiro Yamada [trini: Fixup include/clk.] Signed-off-by: Tom Rini

mtd: OneNAND: initialize mtd->writebufsize to let UBI work

2016-07-22T18:46:12Z

io_init checks this value and fails with "bad write buffer size 0 for 2048 min. I/O unit" Signed-off-by: Ladislav Michl

mtd: OneNAND: add timeout to wait ready loops

2016-07-22T18:46:11Z

Add timeout to onenand_wait ready loop as it hangs here indefinitely when chip not present. Once there, do the same for onenand_bbt_wait as well (note: recent Linux driver code does the same) Signed-off-by: Ladislav Michl

mtd: onenand: Fix unaligned access

2013-12-31T08:59:16Z

Fix unaligned access in OneNAND core. The problem is that the ffchars[] array is an array of "unsigned char", but in onenand_write_ops_nolock() can be passed to the memcpy_16() function. The memcpy_16() function will treat the buffer as an array of "unsigned short", thus triggering unaligned access if the compiler decided ffchars[] to be not aligned. I managed to trigger the problem with regular ELDK 5.4 GCC compiler. Signed-off-by: Marek Vasut Cc: Albert Aribaud Cc: Scott Wood Cc: Tom Rini
