To support UBI in SPL we need a simple NAND read function. Add one to

As part of Chain of Trust for Secure boot, the SPL U-Boot will validate
the next level U-boot image. Add a new function spl_validate_uboot to
perform the validation.
Enable hardware crypto operations in SPL using SEC block.
In case of Secure Boot, PAMU is not bypassed. For allowing SEC block
access to CPC configured as SRAM, configure PAMU.

NAND chips are supposed to expose their capabilities through advanced
mechanisms like READID, ONFI or JEDEC parameter tables. While those
methods are appropriate for the bootloader itself, it's way to
complicated and takes too much space to fit in the SPL.
Replace those mechanisms by a dumb 'trial and error' mechanism.
With this new approach we can get rid of the fixed config list that was
used in the sunxi NAND SPL driver.

Split the 'load page' and 'read page' logic in 2 different functions so
we can later load the page and test different ECC configs without the
penalty of reloading the same page in the NAND cache.
We also move common setup to a dedicated function (nand_apply_config()) to
avoid rewriting the same values in NFC registers each time we read a page.
These new functions are passed a pointer to an nfc_config struct to limit
the number of parameters.

check_value_xxx() helpers are using a 1ms delay between each test, which
can be quite long for some operations (like a page read on an SLC NAND).
Since we don't have anything to do but to poll this register, reduce the
delay between each test to 1us.
While we're at it, rename the max_number_of_retries parameters and the
MAX_RETRIES macro into timeout_us and DEFAULT_TIMEOUT_US to reflect that
we're actually waiting a given amount of time and not only a number of
retries.

On modern NAND it's more than recommended to have a backup copy of the
u-boot binary to recover from corruption: bitflips are quite common on
MLC NANDs, and the read-disturbance will corrupt your u-boot partitition
more quickly than what you would see on an SLC NAND.
Add an extra Kconfig option to specify the offset of the redundant u-boot
image.

The SYS_NAND_U_BOOT_OFFS is quite generic, but the Kconfig entry is forced
to explicitly depend on platforms that are not already defining it in their

on SPL selection.

The sunxi SPL NAND controller driver supports use 'BootROM'-like configs,
that is, configs where the ECC bytes and real data are interleaved in the
page instead of putting ECC bytes in the OOB area.
Doing that has several drawbacks:
- since you're interleaving data and ECC bytes you can't use the whole page
otherwise you might override the bad block marker with non-FF bytes.
- to solve the bad block marker problem, the ROM code supports partially
using the page, but this introduces a huge penalty both in term of read
speed and NAND memory usage. While this is fine for rather small
binaries(like the SPL one which is at maximum 24KB large), it becomes
non-negligible for the bootloader image (several hundred of KB).
- auto-detection of the page size is not reliable (this is in my opinion
the biggest problem). If you get the page size wrong, you'll end up
reading data at a different offset than what was specified by the caller
and the reading may succeed (if valid data were written at this address).
For all those reasons I think it's wiser to completely remove support for
'syndrome' configs. If we ever need to support it again, then I'd recommend
specifying all the config parameters through Kconfig options.

Linux v4.1 in commit d3963721d93fafa.

nand_info[] is now an array of pointers, with the actual mtd_info
instance embedded in struct nand_chip.
This is in preparation for syncing the NAND code with Linux 4.6,

commit due to the large amount of changes required to accommodate the
change to nand_info[].
