16101726e8 mtd: rawnand: brcmnand: Fix ECC level field setting for v7.2 controller
Backport from the Linux kernel
commit 2ec2839a9062db8a592525a3fdabd42dcd9a3a9b
"mtd: rawnand: brcmnand: Fix ECC level field setting for v7.2 controller"

v7.2 controller has different ECC level field size and shift in the acc
control register than its predecessor and successor controller. It needs
to be set specifically.

948616894c mtd: spi-nor: scale up timeout for full-chip erase
This patch fixes timeout issues seen on large NOR flash.
For full-chip erase, where we use the SPINOR_OP_CHIP_ERASE (0xc7)
opcode. Use a different timeout for full-chip erase than for other
commands.

Simon Glass <sjg@chromium.org> says:

This series includes the patches needed to make make the EFI 'boot' test
work. That test has now been split off into a separate series along with
the EFI patches.

This series fixes these problems:
- sandbox memory-mapping conflict with PCI
- the fix for that causes the mbr test to crash as it sets up pointers
  instead of addresses for its 'mmc' commands
- the mmc and read commands which cast addresses to pointers
- a tricky bug to do with USB keyboard and stdio
- a few other minor things

35ff967a99 mtd: rawnand: meson: read/write access for boot ROM pages
Boot ROM on Meson needs some pages to be read/written in a special mode:
384 byte ECC mode (so called "short" by Amlogic) and with scrambling
enabled. Such pages are located on the chip in the following way (for
example):

[ p0 ][ p1 ][ p2 ][ p3 ][ p4 ][ p5 ][ p6 ][ p7 ] ... [ pN ]
  ^           ^           ^           ^

pX is page number "X". "^" means "special" page used by boot ROM - e.g.
every 2nd page in the range of [0, 7]. Step (2 here) and last page in
range is read from the device tree.

9daad11ad1 drivers: introduce UBI block abstraction
UBI block is an virtual device, that runs on top
of the MTD layer. The blocks are UBI volumes.
Intended to be used in combination with other MTD
drivers.

Despite the fact that it, like mtdblock abstraction,
it used with UCLASS_MTD, they can be used together
on the system without conflicting. For example,
using bcb command:

  # Trying to load bcb via mtdblock:
  $ bcb load mtd 0 mtd_partition_name

  # Trying to load bcb via UBI block:
  $ bcb load ubi 1 ubi_volume_name

User always must attach UBI layer (for example, using
ubi_part()) before using UBI block device.

aad8aa56d9 mtd: nand: pxa3xx: Incorrect bitflip return on page read
Once a page is read with higher bitflips all subsequent reads
are returning the same bitflip value even though they have none.
max_bitflip variable is not being reset to 0 across page reads.

This is causing problems like incorrectly
marking erase blocks bad by UBI and causing read failures.

Verified the change with both MTD reads and UBI.
This change is inline with other NFC drivers.

Sample error log where a block is marked bad incorrectly:

ubi0: fixable bit-flip detected at PEB 125
ubi0: run torture test for PEB 125
ubi0: fixable bit-flip detected at PEB 125
ubi0 error: torture_peb: read problems on freshly erased PEB 125,

was added to the driver instead of the header file.  Move it over to the
other definitions with the same help text it has in Linux.

Code actually using this has not been ported over to raw nand base yet.

602b879efd mtd: nand: arasan: Print warning for unsupported ecc modes
Currently only hw ecc is supported in U-Boot. If any other ecc mode is
given in DT, it simply through an error. So better print
what is being done.

Revert this patch once soft ecc support is fixed in future.
