mtd: nand: localize ECC failures per page · b72f3dfb

Brian Norris authored Dec 03, 2013

ECC failures can be tracked at the page level, not the do_read_ops level
(i.e., a potentially multi-page transaction).

This helps prepare for READ RETRY support.

mtd: denali: kill the NAND_MAX_PAGESIZE/NAND_MAX_OOBSIZE · e07caa36

Huang Shijie authored Dec 21, 2013

This patch kills the NAND_MAX_PAGESIZE/NAND_MAX_OOBSIZE by the following
way:
 1.) change the @buf field of nand_buf{} from an array to a pointer.
     also remove the DENALI_BUF_SIZE macro.

 2.) Before we call the nand_scan_ident, we allocate a temporary buffer
     whose size is PAGE_SIZE.

 3.) After we finish the nand_scan_ident, we have already getten the
     page size and oob size. We will allocate the right buffer size
     again.

mtd: denali: Drop print of build date/time · 88c30591

Josh Triplett authored Dec 23, 2013

The kernel already has this information, and individual drivers
shouldn't duplicate that.  This also eliminates the use of __DATE__ and
__TIME__, which make the build non-deterministic.

mtd: bcm47xxpart: alternative MAGIC for board_data partition · f0501e81

Rafał Miłecki authored Dec 21, 2013

Some devices (like WNDR3700v3) have board_data without MPFR magic, some
extra header or extra NVRAM around 0x100. In such case we have to look
for another magic which is BD 0B 0D BD (BD probably stands for Board
Data). It's located "far far away", so instead of extending buffer add
another mtd_read.

mtd: nand-gpio: don't waste memory for OF failure · 103cdd85

We shouldn't try to allocate a resource until we're sure the
of_property_read_u64() call didn't fail. This is especially important if
we use this code for both CONFIG_OF and !CONFIG_OF builds, since
of_property_read_u64() will always return -ENOSYS for !CONFIG_OF.
