bdfd59aa0f at91: atmel_nand: Update driver to support Programmable Multibit ECC controller
The Programmable Multibit ECC (PMECC) controller is a programmable binary
BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller
can be used to support both SLC and MLC NAND Flash devices. It supports to
generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data.

To use PMECC in this driver, the user needs to set the PMECC correction
capability, the sector size and ROM lookup table offsets in board config file.

This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference
is in this version it uses registers structure access hardware instead of using macros.
It is tested in 9x5 serial boards.

fe2185ea80 at91: atmel_nand: extract HWECC initialization code into one function: atmel_hw_nand_init_param().
This patch
1. extract the hwecc initialization code into one function. It is a preparation for adding atmel PMECC support.
2. enable CONFIG_SYS_NAND_SELF_INIT. Which make us can configurate the ecc parameters between nand_scan_ident() and nand_scan_tail().

3e8581bb95 usb_stor_BBB_transport: Do not delay when not required
There is a 5-ms delay in usb_stor_BBB_transport, which occurs every 10 kiB of
data for fragmented fatload usb, i.e. roughly 500 ms of delay per MiB. This adds
up to quite a bit of delay if you're loading a large ramdisk.

The purpose of this delay should be to debounce the 5-V/100-mA USB power up.
This patch skips the delay if the device has already been queried as ready.

5cec214ecd ehci-hcd: Boost transfer speed
This patch takes advantage of the hardware EHCI qTD queuing mechanism to avoid
software and transfer splitting overhead so as to make transfers as fast as
possible.

The only drawback is a call to memalign. However, this is fast compared to the
transfer timings, and the heap size to allocate is small, e.g. 128 kiB in the
worst case for a transfer length of 65535 packets of 512 bytes.

Tested on i.MX25, i.MX35 and i.MX51. In my test conditions, the speed gain was
very significant (several times faster), which is really appreciable when
accessing large files.

10e2178b43 efikamx: sync Smartbook DDR settings in DCD with those found in Genesi's production U-Boot
We have no idea where the DCD was derived from for Smartbook support, but they
differ from the Smarttop settings, MX51EVK settings and certainly don't
correspond to any shipped or development version of U-Boot that Genesi has ever
had on any Smartbook.

So, copy the calibrated, verified settings from the U-Boot as shipped with every
Smartbook since retail production. Remove those few settings that just set the
POR defaults which have already been confirmed for the previous Smarttop DCD
change.

One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks
will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks
basically don't exist at retail and the number of units in the world is less
than 5 (3 of which are at the Genesi office or owned by Genesi employees).

Many hours of memory testing confirms the new settings are stable.

Patch v2:
 * picked the correct commit from our development tree, correcting tuned DDR ODF setting
   (which was correct anyway)

fdd63c9352 efikamx: update to Efika MX Smarttop and Smartbook boards
This is a rework of a previously submitted patchset and bundles the
main board support and USB support into a single commit.

It requires the patch "mx5: add iomux-mx51.h include"

* Use iomux-mx51.h include to simplify board configuration.
* Simplify LED support (remove efikamx_toggle_led, change lit LEDs).
* Simplify MMC support for CD and WP pin differences.
* Fix broken CPU voltage setting - comment said 1.1V but the code set to
  1.2V. It should never have been set to 1.2V even on i.MX51 TO2 and
  all available Linux kernels would drop the voltage to 1.1V anyway and
  work reliably. This should lower power consumption during the boot
  process.
* Function renames for readability.
* Some board identification string changes to match actual product names.
* Passes checkpatch (v2)

0001c9f71e efikamx: configure Smarttop PCBID and LED pads in DCD for convenience
PCBID pads seem to need time to settle due to external pulldowns, otherwise
we are reading floating GPIO pins with implicit pad pullups and get the wrong
data. However we can't "wait" at the time we need them before relocation,
since timers are not available. The time taken to get from DCD to the code
requiring the pads set seems to be more than long enough (even with caches
enabled).

We have space in the DCD due to the DDR settings changes to configure all
the pad settings we need for this, plus the LED pad settings too which
reduces the amount of code required later on.

ff9ab7c2e4 efikamx: remove drive strength function and roll its functionality into the DCD
Efika MX boards configure their DDR pad settings twice, one in the DCD generated
from imximage_*.cfg and again in init_drive_strength called before relocation.

Rather than doing this, roll the changes it makes into the DCD so DDR is set up
before a single line of code in U-Boot is run.

The settings are identical with this DCD block which is shorter (by 7 entries)
than the old one, and after the output of init_drive_strength since a lot of the
functionality in the existing DCD and init_drive_strength function was just
setting the POR defaults. This goes to explain some now-missing entries.

Several hundred rounds of mtest have been run to test the settings before and
after to confirm DDR is stable and no ill-effects have been found.

This change implements DMA chaining into SPI driver. This allows
the transfers to go much faster, while also fixing SF issues.

1375f044d9 MX28: DMA: Prolong the DMA timeout
Load from SPI flash can create a long DMA chain, which can take long
time to transfer. Change the DMA timeout to roughly 10s to prevent
such long chains misreporting errors.
