Subject: [U-Boot] [PATCH V4 0/4] mtd/NAND: Support for FSMC controller
Date: Fri, 18 May 2012 11:30:09 +0530 [thread overview]
Message-ID: <cover.1337320290.git.amit.virdi@st.com> (raw)
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.
V3->V4
- Removed local_irq_save and local_irq_restore calls from change_bit wrapper
- Report the total bit flips, including that of ECC, to the upper layers
- Replace change_bit calls for err_idx's 0th and 1st bit with "^= 3" operation
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
