5701ba8289 cfi_flash: Bound-check index before array access
In a while loop in cfi_flash.c the array "start" is accessed at the index
"sector" before the index variable "sector" is bounds-checked, which
might lead to accesses beyond the bounds of the array.

Swap the order of the checks in the "&&" expression, so that the
short-circuit evaluation prevents out-of-bounds array accesses.

5312838dd5 cfi_flash: Use u8 pointers instead of void pointers
According to the C standard, pointer arithmetic for pointers of type
void is undefined behavior (the assumption that they're 8-bit wide is a
GCC-specific assumption). In the interest of keeping the code
standards-compliant, and also better communicate intent, switch all
void* variables where pointer arithmetic is used to u8* variables.

register used to determine this feature is not backward compati-
ble. Older flash chips without this feature has reserved value
0xff. Instead of checking "lower software bits" register, use
CFI primary vendor-specific extended query. Since CFI version
1.4, software features can be read from offset 0x53 according to
document AN201168 from Cypress.

e6001371d1 mtd: nand: introduce NAND_ROW_ADDR_3 flag
Several drivers check ->chipsize to see if the third row address cycle
is needed.  Instead of embedding magic sizes such as 32MB, 128MB in
drivers, introduce a new flag NAND_ROW_ADDR_3 for clean-up.  Since
nand_scan_ident() knows well about the device, it can handle this
properly.  The flag is set if the row address bit width is greater
than 16.

Delete comments such as "One more address cycle for ..." because
intention is now clear enough from the code.

470c29d1c2 mtd: nand: add generic helpers to check, match, maximize ECC settings
Driver are responsible for setting up ECC parameters correctly.
Those include:
  - Check if ECC parameters specified (usually by DT) are valid
  - Meet the chip's ECC requirement
  - Maximize ECC strength if NAND_ECC_MAXIMIZE flag is set

The logic can be generalized by factoring out common code.

This commit adds 3 helpers to the NAND framework:
nand_check_ecc_caps - Check if preset step_size and strength are valid
nand_match_ecc_req - Match the chip's requirement
nand_maximize_ecc - Maximize the ECC strength

To use the helpers above, a driver needs to provide:
  - Data array of supported ECC step size and strength
  - A hook that calculates ECC bytes from the combination of
    step_size and strength.

By using those helpers, code duplication among drivers will be
reduced.

c7c553f249 mtd: nand: Wait for PAGEPROG to finish in drivers setting NAND_ECC_CUSTOM_PAGE_ACCESS
Drivers setting NAND_ECC_CUSTOM_PAGE_ACCESS are supposed to handle the
full read/write page sequence, and waiting for a page to actually be
programmed is part of this write-page sequence.
This is also what is done in ->write_oob_xxx() hooks, so let's do that in
->write_page_xxx() as well to make it consistent.

3d841b3214 mtd: nand: Fix data interface configuration logic

One of these constraints is that the CE line has go high after a reset
before a command can be sent with the new data interface setting, which
is not guaranteed by the current implementation.

Rework the nand_reset() function and all the call sites to make sure the
CE line is asserted and released when required.

27c4792cd2 mtd: nand: automate NAND timings selection
The NAND framework provides several helpers to query timing modes supported
by a NAND chip, but this implies that all NAND controller drivers have
to implement the same timings selection dance. Also currently NAND
devices can be resetted at arbitrary places which also resets the timing
for ONFI chips to timing mode 0.

Provide a common logic to select the best timings based on ONFI or
->onfi_timing_mode_default information. Hook this into nand_reset()
to make sure the new timing is applied each time during a reset.

NAND controller willing to support timings adjustment should just
implement the ->setup_data_interface() method.

19d30ded88 mtd: nand: Add an option to maximize the ECC strength
The generic NAND DT bindings allows one to tweak the ECC strength and
step size to their need. It can be used to lower the ECC strength to
match a bootloader/firmware config, but might also be used to get a better
reliability.

In the latter case, the user might want to use the maximum ECC strength
without having to explicitly calculate the exact value (this value not
only depends on the OOB size, but also on the NAND controller, and can
be tricky to extract).

Add a generic 'nand-ecc-maximize' DT property and the associated
NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best
ECC strength and step-size on their own.

Currently the chipselect used to identify the corresponding NAND chip
is stored at the controller and only set during fsl_ifc_chip_init().
This way, only the last NAND chip is working, as the previous value
of cs_nand gets overwritten.

In order to solve this issue the chipselect is computed on demand by
evaluating the bank variable. Thus, the correct chipselect for each
NAND chip operation is used.

Tested on hardware with two NAND chips connected to the IFC

ca1ac16da0 sf: bar: Clean BA24 Bank Address Register bit after read/write/erase operation
The content of Bank Address Register (BAR) is volatile. It is cleared
after power cycle or reset command (RESET F0h).

Some memories (like e.g. s25fl256s) use it to access memory larger than
0x1000000 (16 MiB).

The problem shows up when one:

1. Reads/writes/erases memory > 16 MiB
2. Calls "reset" u-boot command (which is not causing BAR to be cleared)

In the above scenario, the SoC ROM sends 0x000000 address to read SPL.
Unfortunately, the BA24 bit is still set and hence it receives content
from 0x1000000 (16 MiB) memory address.
As a result the SoC aborts and we hang. Only power cycle can take the
SoC out of this state.

How to reproduce/test:

sf probe; sf erase 0x1200000 0x800000; reset
sf probe; sf erase 0x1200000 0x800000; sf write 0x11000000 0x1200000 0x800000; reset
sf probe; sf read 0x11000000 0x1200000 0x800000; reset

It was not merged and I do not see on-going work for this.

Without DM-based probing, we need to set up pinctrl etc. in an ad-hoc
way and give lots of crappy CONFIG options for base addresses and
properties, which are supposed to be specified by DT.  This is painful.

This commit just provides a probe hook to retrieve "reg" from DT and
allocate private data in a DM manner.  This DT driver is not essentially
a NAND driver, in fact it is (ab)using UCLASS_MISC.  Once UCLASS_NAND is
supported, it would be possible to migrate to it.

294f2050c4 sf: Preserve QE bit when clearing BP# bits for Macronix flash
On some flash (like Macronix), QE (quad enable) bit is in the same
status register as BP# bits, and we need preserve its original value
during a reboot cycle as this is required by some platforms (like
Intel ICH SPI controller working under descriptor mode).

00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.
