Add CONFIG_BOOTCOUNT_ALTBOOTCMD so the developer is able to add
custom altbootcmd via Kconfig when they enable BOOTCOUNT. With this now
in Kconfig, we need to move it from environment files / config.h files
and in to the defconfig file.
This was done by generating u-boot-initial-env for all platforms before
the Kconfig change, to extract altbootcmd values and then again after to
compare the result.

Modern eMMC v4+ devices have multiple hardware partitions per the JEDEC
specification described as:
Boot Area Partition 1
Boot Area Partition 2
RPMB Partition
General Purpose Partition 1
General Purpose Partition 2
General Purpose Partition 3
General Purpose Partition 4
User Data Area
These are referenced by fields in the PARTITION_CONFIG register
(Extended CSD Register 179) which is defined as:
bit 7: reserved
bit 6: BOOT_ACK
0x0: No boot acknowledge sent (default
0x1: Boot acknowledge sent during boot operation Bit
bit 5:3: BOOT_PARTITION_ENABLE
0x0: Device not boot enabled (default)
0x1: Boot Area partition 1 enabled for boot
0x2: Boot Area partition 2 enabled for boot
0x3-0x6: Reserved
0x7: User area enabled for boot
bit 2:0 PARTITION_ACCESS
0x0: No access to boot partition (default)
0x1: Boot Area partition 1
0x2: Boot Area partition 2
0x3: Replay Protected Memory Block (RPMB)
0x4: Access to General Purpose partition 1
0x5: Access to General Purpose partition 2
0x6: Access to General Purpose partition 3
0x7: Access to General Purpose partition 4
Note that setting PARTITION_ACCESS to 0x0 results in selecting the User
Data Area partition.
You can see above that the two fields BOOT_PARTITION_ENABLE and
PARTITION_ACCESS do not use the same enumerated values.
U-Boot uses a set of macros to access fields of the PARTITION_CONFIG
register:
EXT_CSD_BOOT_ACK_ENABLE (1 << 6)
EXT_CSD_BOOT_PARTITION_ENABLE (1 << 3)
EXT_CSD_PARTITION_ACCESS_ENABLE (1 << 0)
EXT_CSD_PARTITION_ACCESS_DISABLE (0 << 0)
EXT_CSD_BOOT_ACK(x) (x << 6)
EXT_CSD_BOOT_PART_NUM(x) (x << 3)
EXT_CSD_PARTITION_ACCESS(x) (x << 0)
EXT_CSD_EXTRACT_BOOT_ACK(x) (((x) >> 6) & 0x1)
EXT_CSD_EXTRACT_BOOT_PART(x) (((x) >> 3) & 0x7)
EXT_CSD_EXTRACT_PARTITION_ACCESS(x) ((x) & 0x7)
There are various places in U-Boot where the BOOT_PARTITION_ENABLE field
is accessed via EXT_CSD_EXTRACT_PARTITION_ACCESS and converted to a
hardware partition consistent with the definition of the
PARTITION_ACCESS field used by the various mmc_switch incarnations.
To add some sanity to the distinction between BOOT_PARTITION_ENABLE
(used to specify the active device on power-cycle) and PARTITION_ACCESS
(used to switch between hardware partitions) create two enumerated types
and use them wherever struct mmc * part_config is used or the above
macros are used.
Additionally provide arrays of the field names and allow those to be
used in the 'mmc partconf' command and in board support files.
The first patch adds enumerated types and makes use of them which
represents no compiled code change.
The 2nd patch adds the array of names and uses them in the 'mmc
partconf' command.
The 3rd patch uses the array of hardware partition names in a board
support file to show what emmc hardware partition U-Boot is being loaded
from.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

CONFIG_SYS_BOOT_LOCKED means that a restricted boot environment will
be used. In this case, hab_auth_img_or_fail should be called to prevent
U-Boot to continue running when the fitImage authentication fails.
Fix the logic accordingly.
Additionally, select CONFIG_SYS_BOOT_LOCKED by default.

Currently, only the first MAC address is read from the fuses.
The second MAC address is not read and Linux assigns a random one.
To prevent this behavior, read the second MAC address from the fuses
and store it into the eth1addr environment variable so that it
can be passed to Linux.

GPT Partition labels are used for determining the right
root filesystem to boot from.
The U-Boot environment is configured to reside in the eMMC hardware
boot partition we are currently booted from.
This should enable a dual copy approach for upgrading the bootloader.
One can overwrite the inactive hardware partition with new bootloader
and environment and afterwards switch the eMMC boot partition for an
atomic bootloader switch.
