Re: [U-Boot] [PATCH 00/22] mtd: nand: imports NAND core updates from Linux 4.15-rc1 and sync Denali driver

My motivation is to complete syncing the Denali driver with Linux.

However, the last sync of NAND core was Linux 4.6 so a lots of parts are missing in U-Boot.

I imported the following:

• NAND_ECC_MAXIMIZE flag
• nand_data_interface
• sync nand_timings
• NAND_ECC_CUSTOM_PAGE_ACCESS
• mtd_ooblayout_xxx()
• chip->buf_align
• helpers to match ECC requirement
• NAND_ROW_ADDR_3

The blind syncing often broke drivers.

Forcible syncing often broke drivers in the past. This time, I imported necessary commits one by one. I put the corresponding commit ID in Linux. And, it should be easy to review that the existing drivers are not affected.

Lastly, I updated the Denali driver. I tested it on my boards and worked for me. It is nicely synced with Linux.

Applied to u-boot-uniphier.
