The gpmi driver performance suffers from NAND operations being split
in multiple small DMA transfers. This has been forced by the NAND layer
in the former days, but now with exec_op we can use the controller as
intended.
With this patch gpmi_nfc_exec_op becomes the main entry point to NAND
operations. Here all instructions are collected and chained as separate
DMA transfers. In the end whole chain is fired and waited to be
finished. gpmi_nfc_exec_op only does the hardware operations, bad block
marker swapping and buffer scrambling is done by the callers. It's worth
noting that the nand_*_op functions always take the buffer lengths for
the data that the NAND chip actually transfers. When doing BCH we have
to calculate the net data size from the raw data size in some places.
This patch has been tested with 2048/64 and 2048/128 byte NAND on
i.MX6q. mtd_oobtest, mtd_subpagetest and mtd_speedtest run without
errors. nandbiterrs, nandpagetest and nandsubpagetest userspace tests
from mtdutils run without errors and UBIFS can successfully be mounted.

Then, if RE# access time is bigger than RE# pulse width, the real

read performance be worse than that expected.
This patch improves data sampling timing by calculating RE# low level

At present, the flow of calculating AC timing of read/write cycle in SDR
mode is that:
At first, calculate high hold time which is valid for both read and write
cycle using the max value between tREH_min and tWH_min.
Secondly, calculate WE# pulse width using tWP_min.
Thridly, calculate RE# pulse width using the bigger one between tREA_max
and tRP_min.
But NAND SPEC shows that Controller should also meet write/read cycle time.
That is write cycle time should be more than tWC_min and read cycle should
be more than tRC_min. Obviously, we do not achieve that now.
This patch corrects the low level time calculation to meet minimum
read/write cycle time required. After getting the high hold time, WE# low
level time will be promised to meet tWP_min and tWC_min requirement,
and RE# low level time will be promised to meet tREA_max, tRP_min and
tRC_min requirement.

Sometimes the exec_op parser does not choose the optimal pattern if
multiple patterns with optional elements are available. Since the stack
automatically splits operations in multiple exec_op calls, a non-optimal
pattern gets broken up into multiple calls. E.g. an OOB read using the
vf610 driver:
nand: executing subop:
nand: ->CMD [0x00]
nand: ->ADDR [5 cyc: 00 08 ea 94 02]
nand: ->CMD [0x30]
nand: ->WAITRDY [max 200000 ms]
nand: DATA_IN [64 B]
nand: executing subop:
nand: CMD [0x00]
nand: ADDR [5 cyc: 00 08 ea 94 02]
nand: CMD [0x30]
nand: WAITRDY [max 200000 ms]
nand: ->DATA_IN [64 B]
However, the vf610 driver has a pattern which can execute the complete
command in a single go...
This patch makes sure that the longest matching pattern is chosen
instead of the first (potentially only partial) match. With this
change the vf610 reads the OOB in a single exec_op call:
nand: executing subop:
nand: ->CMD [0x00]
nand: ->ADDR [5 cyc: 00 08 c0 1d 00]
nand: ->CMD [0x30]
nand: ->WAITRDY [max 200000 ms]
