mtd: Fallback to ->_read/write_oob() when ->_read/write() is missing

2018-09-20T14:40:49Z

Some MTD sublayers/drivers are implementing ->_read/write_oob() and provide dummy wrappers for their ->_read/write() implementations. Let the core handle this case instead of duplicating the logic.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

mtd: replace MTDDEBUG() with pr_debug()

2017-10-23T18:07:26Z

In old days, the MTD subsystem in Linux had debug facility like DEBUG(MTD_DEBUG_LEVEL1, ...). They were all replaced with pr_debug() until Linux 3.2. See Linux commit 289c05222172 ("mtd: replace DEBUG() with pr_debug()"). U-Boot still uses similar macros. Covert all of them for easier sync. Done with the help of Coccinelle. The semantic patch I used is as follows: // @@ expression e1, e2; @@ -MTDDEBUG(e1, e2) +pr_debug(e2) @@ expression e1, e2; @@ -MTDDEBUG(e1, e2, +pr_debug(e2, ...) // Signed-off-by: Masahiro Yamada

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

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
