[U-Boot] [PATCH V3 RESEND 0/4] mtd/NAND: Support for FSMC controller

[Amit Virdi]

This patchset adds support for ST's FSMC controller. In the current u-boot, a
SPEAr specific driver exists for FSMC controller.  This patchset adds a full
fledged driver that can be used across multiple platforms and removes the
obsolete SPEAr specific driver.

V2 -> V3
 - Implemented timeout during hardware ecc read
 - Used __attribute__ ((aligned(2))) instead of using array of U16
 - Removed unnecessary enum

V1 -> V2
 - Defined CONFIG_SYS_NAND_SELF_INIT and did the related changes
 - Modified the error index calculation process
 - Modified newly erased page read algorithm
 - Initialized the badblockbits index to 7
 - Improved fsmc_bch8_correct_data() implementation
