177040b1eb sunxi: Kconfig: use SoC-wide values for some symbols
Some configuration symbols formerly defined in header files were
recently converted to Kconfig symbols. This moved their value definition
into *every* defconfig file, even though those values are hardly board
choices.
Use the new Kconfig option to define per-SoC default values, in just one
place, which makes the definition in each defconfig file redundant.

We refrain from setting a sunxi specific value for CONFIG_SYS_BOOTM_LEN,
so this defaults to a much better 64MB for uncompressed arm64 kernels.

7f8967c2b8 blk: Rename HAVE_BLOCK_DEVICE
This option is fact really related to SPL. For U-Boot proper we always use
driver model for block devices, so CONFIG_BLK is enabled if block devices
are in use.

It is only for SPL that we have two cases:

- SPL_BLK is enabled, in which case we use driver model and blk-uclass.c
- SPL_BLK is not enabled, in which case (if we need block devices) we must
  use blk_legacy.c

Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is
different enough from BLK and SPL_BLK that there should be no confusion.

6516c9b349 spl: binman: Disable u_boot_any symbols for i.MX8M boards
The i.MX8M boards use partially specified binman images which have an
SPL entry without a U-Boot entry. This would normally cause an error due
to the 'u_boot_any' binman symbols declared by BINMAN_UBOOT_SYMBOLS
requiring a U-Boot-like entry in the same image as the SPL.

However, a problem in the ARMv8 __image_copy_start symbol definition
effectively disables binman from attempting to write any symbols at all,
so everything appears to work fine until runtime. A future patch fixes
the issue in the linker scripts, which lets binman fill in the symbols,
which would result in the build error described above.

Explicitly disable the 'u_boot_any' symbols for i.MX8M boards. They are
already effectively unusable, and they are incompatible with the boards'
current binman image descriptions.

d8830cf840 spl: binman: Split binman symbols support from enabling binman
Enabling CONFIG_BINMAN makes binman run after a build to package any
images specified in the device-tree. It also enables a mechanism for
SPL/TPL to declare and use special linker symbols that refer to other
entries in the same binman image. A similar feature that gets this info
from the device-tree exists for U-Boot proper, but it is gated behind a
CONFIG_BINMAN_FDT unlike the symbols.

Confusingly, CONFIG_SPL/TPL_BINMAN_SYMBOLS also exist. These configs
don't actually enable/disable the symbols mechanism as one would expect,
but declare some symbols for U-Boot using this mechanism.

Reuse the BINMAN_SYMBOLS configs to make them toggle the symbols
mechanism, and declare symbols for the U-Boot phases in a dependent
BINMAN_UBOOT_SYMBOLS config. Extend it to cover symbols of all phases.
Update the config prompt and help message to make it clearer about this.
Fix binman test binaries to work with CONFIG_IS_ENABLED(BINMAN_SYMBOLS).

22eb1526d4 spl: Convert SYS_MMCSD_RAW_MODE_KERNEL_SECTOR to Kconfig
Falcon mode is very useful in improving boot speed. A question that
Falcon mode asks is "Where do I look for the kernel". With MMC boot
media, the correct answer is CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR.
The scope of this patch is to move this to Kconfig.

It is possible for a system to support Falcon mode from NOR but not
MMC. In that case, mmc_load_image_raw_os() would not be used. To
address this, conditionally compile mmc_load_image_raw_os() when
SPL_FALCON_BOOT_MMCSD, instead of SPL_OS_BOOT.
