nand: vybrid: Use calloc() instead of malloc() to allocate struct nfc

Without this change it is possible that Vybrid's NFC driver malloc() call
will obtain some memory used (and correctly free'd) by some previous
driver (in this case pinctrl for Vybrid).

As a result some fields of struct nfc - in out case mtd->_get_device - are
"pre initialized" with some random values.

On the latter stage of booting, when e.g. somebody calls 'mtdparts default'
the "data abort" is observed when __get_mtd_device() function is called.

The mtd->_get_device pointer is not NULL and wrong value is referenced.

5 years agopcm058: fix NAND flash not using badblock table
Harald Seiler [Fri, 7 Dec 2018 09:19:36 +0000 (10:19 +0100)]
pcm058: fix NAND flash not using badblock table

Currently, U-Boot ignores the BBT stored in the last 4 blocks of NAND
flash because the NAND_BBT_USE_FLASH flag is not set.  This leads to
two issues:

* U-Boot silently uses a memory-only BBT which is initialized with all
  blocks marked as good.  This means, actual bad blocks are marked good
  and U-Boot might try writing to or reading from them.
* The BBT in flash, which will be created once Linux boots up, is not
  off limits for a driver ontop, like UBI.  While it does not seem to
  consistently produce an error, sometimes UBI will fail to attach
  because the BBT blocks obviously don't contain valid UBI data.

To fix this, this patch sets the CONFIG_SYS_NAND_USE_FLASH_BBT option,
which is used in ./drivers/mtd/nand/raw/mxs_nand.c to decide whether
a BBT in flash is used.
