2016-02-02atmel_nand: Add 32 bit ecc support for sama5d2 chipJosh Wu
Also if minimum ecc requirment is bigger then what we support, then just use our maxium pmecc support. But it is not safe, so we'll output a warning about this.

2016-02-02atmel_nand_ecc: update pmecc registers according to sama5d2 chipJosh Wu
1. add the pmecc register mapping for sama5d2. 2. add the pmecc error location register mapping for sama5d2. 3. add some new field that is different from old ip. 4. add sama5d2 pmecc ip version number.

2016-01-25bug.h: move BUILD_BUG_* defines to include/linux/bug.hMasahiro Yamada
BUILD_BUG_* macros have been defined in several headers. It would be nice to collect them in include/linux/bug.h like Linux. This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot. I'd like to postpone it until the root cause (the "error()" macro in include/common.h causes the name conflict with "__attribute__((error()))") is fixed.

2016-01-21spi: Correct device tree usage in spi_flash_decode_fdt()Simon Glass
This function currently searches the entire device tree for a node that it thinks is relevant. But the node is known and is passed in. Correct the code and enable it only with driver model, since only driver-model boards will use it. This avoids bringing in a large number of strings from fdtdec.
