spl: nand: sunxi: add support for NAND config auto-detection
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

We also move common setup to a dedicated function (nand_apply_config()) to

These new functions are passed a pointer to an nfc_config struct to limit

spl: nand: sunxi: remove support for so-called 'syndrome' mode
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.

arm: socfpga: improve raw MMC SPL boot
Before this patch, when booting from MMC (no filesystem), the SPL
loaded U-Boot from a fixed offset.
It will now load U-Boot from an offset of 256kB (which is 4 times the
padded SPL image) in the third partition.
This behaviour is similar to what the vendor SPL (based on
U-Boot 2013.01) does, and allows to directly 'dd' the

Since commit 56adbb387273 ("image.h: Tighten up content using handy
CONFIG_IS_ENABLED() macro."), I found my boards fail to boot Linux
because the commit changed the logic of macros it touched. Now,
IMAGE_ENABLE_RAMDISK_HIGH and IMAGE_BOOT_GET_CMDLINE are 0 for all
the boards.
As you can see in include/linux/kconfig.h, CONFIG_IS_ENABLE() (and
IS_ENABLED() as well) can only take a macro that is either defined
as 1 or undefined. This is met for boolean options defined in
Kconfig. On the other hand, CONFIG_SYS_BOOT_RAMDISK_HIGH and
CONFIG_SYS_BOOT_GET_CMDLINE are defined without any value in
arch/*/include/asm/config.h . This kind of clean-up is welcome,
but the options should be moved to Kconfig beforehand.
Moreover, CONFIG_IS_ENABLED(SPL_CRC32_SUPPORT) looks weird.
It should be either CONFIG_IS_ENABLED(CRC32_SUPPORT) or
IS_ENABLED(CONFIG_SPL_CRC32_SUPPORT). But, I see no define for
CONFIG_SPL_CRC32_SUPPORT anywhere. Likewise for the other three.
The logic of IMAGE_OF_BOARD_SETUP and IMAGE_OF_SYSTEM_SETUP were
also changed for SPL. This can be a problem for boards defining
CONFIG_SPL_OF_LIBFDT. I guess it should have been changed to
IS_ENABLED(CONFIG_OF_BOARD_SETUP).
In the first place, if we replace the references in C code,
the macros IMAGE_* will go away.

MIPS: Abstract cache op loops with a macro
The various cache maintenance routines perform a number of loops over

abstract it out into a new cache_loop macro which performs an arbitrary
