[U-Boot] [PATCH v7 0/2] SPL: Add support to boot a partition type

[U-Boot] [PATCH v7 0/2] SPL: Add support to boot a partition type

[Dalon Westergreen]

This adds support for the spl to seach for and boot from an arbitrary
partition type rather then a specific partition number.  When
USE_PARTITION_TYPE is enabled, spl will search for the partition type but
fallback to the specified partition number.
 
SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION is moved to a Kconfig and header and
defconfigs for the affected boards are updated.

Changes in v8:
 -> Move partition type default to arch/arm/mach-socfpga/Kconfig
Changes in v7:
 -> set part type to 0xa2 only if socfpga selected and merge previously split
    patch
Changes in V6:
 -> Fix unneeded backslash
 -> Move SPL socfpga Kconfig default to selec tin arch/arm/Kconfig
 -> Split out defconfig changes for affected boards into a separate patch

[U-Boot] [PATCH v8 1/2] SPL: add support to boot from a partition type

[Dalon Westergreen]

the socfpga bootrom supports mmc booting from either a raw image
starting at 0x0, or from a partition of type 0xa2.  This patch
adds support for locating the boot image in the first type 0xa2
partition found.

Assigned a partition number of -1 will cause a search for a
partition of type CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_TYPE
and use it to find the u-boot image

Changes in v8:
 - Move partition type default to arch/arm/mach-socfpga/Kconfig
Changes in v7:
 - set part type to 0xa2 only if socfpga selected
Changes in V6:
 - Remove unneeded backslash
Changes in V5:
 - fix styling in if (..) per Tom's request
Changes in V4:
 - Try search for partition type and failover to the defined
   partition number
Changes in V3:
 - Add depends on DOS_PARTITION
 - Ensure that PARTTION_TYPE defaults to non-zero
 - Add ifdef around sys_ind in disk_partition structure
Changes in V2:
 - Merge partition search into single partition function

[U-Boot] [PATCH v8 2/2] SPL: Move SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION to Kconfig

[Dalon Westergreen]

Added SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION and
SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION to Kconfig.

Due to SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION being moved to
Kconfig the board defconfigs for db-88f6820-gp_defconfig
kc1_defconfig and sniper_defconfig need to be updated.

Signed-off-by: Dalon Westergreen <dwesterg@gmail.com>

Changes in v4:
  - merge defconfig changes into single patch
Changes in v3:
  - Split off defconfig changes for db-88f6820-gp_defconfig
    kc1_defconfig and sniper_defconfig into a separate patch
Changes in v2:
  - Remove SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION from socfpga_common.h
  - wrong ifdef around mmc_load_image_raw_partition should be
    CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION

Lets just set this part aside.  The most correct answer is that once the

other stuff up to the right level Kconfig where SoCs and boards can say
what reasonable things are based on what's optional and non-optional.
