[U-Boot] [PATCH 00/10] cm-t43 maintenance

[Nikita Kiryanov]

This is a bugfix series for cm-t43 resolving issues with boot and power supply,
as well as some cleanups and minor adjustments. It also update raw mmc boot
parameters for cm-t43, and adds some useful features to the tps65218 driver.

[U-Boot] [PATCH 01/10] arm: am437x: cm-t43: fix cm-t43 boot

[Nikita Kiryanov]

spl_board_init() is necessary for boot. Remove the #undef that keeps
it out of the boot sequence.

[U-Boot] [PATCH 02/10] arm: am437x: cm-t43: migrate CONFIG_DM_SERIAL to config file

[Nikita Kiryanov]

Move CONFIG_DM_SERIAL to cm_t43_defconfig. This forces us to update the
CONFIG_SYS_NS16550_REG_SIZE value for SPL.

[U-Boot] [PATCH 09/10] arm: am437x: cm-t43: set MPU and CORE voltages on boot

[Nikita Kiryanov]

During boot, U-Boot raises the CPU frequency but the CORE and MPU regulators
are not updated. This is not a problem in cold boot since the default values
that the pmic outputs are correct, but if Linux were to switch the module to a
low power OPP, the new voltage values will be retained after a reboot and the
module will likely hang once U-Boot raises the CPU frequency back up.

Set both CORE and MPU regulators to to 1.1V on boot.

[U-Boot] [PATCH] arm: am437x: cm-t43: bring back BOOTDELAY feature

[Nikita Kiryanov]

Commit 755324 (configs: Use config_distro_defaults.h in ti_armv7_common.h)
made ti_armv7_common.h include config_distro_defaults.h. This breaks the
bootdelay feature in cm_t43 because now the
  - #include ti_armv7_common.h (#define CONFIG_BOOTDELAY 1)
  - #undef CONFIG_BOOTDELAY
  - #include config_distro_defaults.h (#define CONFIG_BOOTDELAY 2)
dance in cm_t43.h is no longer valid and in fact leads to CONFIG_BOOTDELAY
not being defined.

Adapt the config file to the new inclusion hierarchy.
