3c01557df8 include: configs: am64x_evm: Add env variables for booting to kernel using USB MSC device
Add env variables for booting to kernel from USB MSC device. The second
partition in the USB MSC device needs to formatted as ext4 file system with
kernel and dtb images, present in the /boot folder.

a2ac2b964b Convert CONFIG_SKIP_LOWLEVEL_INIT et al to Kconfig
This converts the following to Kconfig:
   CONFIG_SKIP_LOWLEVEL_INIT
   CONFIG_SKIP_LOWLEVEL_INIT_ONLY

In order to do this, we need to introduce SPL and TPL variants of these
options so that we can clearly disable these options only in SPL in some
cases, and both instances in other cases.

acbda111b2 configs: am64x_evm: Move CONFIG_SYS_MMC_ENV_DEV and CONFIG_SYS_MMC_ENV_PART to defconfig files and enable configs to save env in eMMC and FAT write.
Kconfig symbols for SYS_MMC_ENV_DEV and SYS_MMC_ENV_PART have been added by
commit 7d08077334. Therefore, move the
definitions of configs to corresponding board defconfig files and enable
configs to save env in eMMC.

Also enable config for FAT write in U-Boot.

26f32c32b2 configs: am64x_evm_*_defconfig: Rearrange the components in SRAM to satisfy the limitations for USB DFU boot mode
For USB DFU boot mode there is a limitation on the load address of boot
images that they have to be less than 0x70001000. Therefore, move the
SPL_TEXT_BASE address to 0x70000000.

Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at
0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move
the location of ATF to a latter location in SRAM, past the SPL image. Also
rearrange the EEPROM and BSS data on top of ATF.

Given below is the placement of various data sections in SRAM

Now that single defconfig can be used for booting AM64 EVM and SK,
default device tree will not work for selecting dtb for kernel.
Update the env to select right dtb based on eeprom.

Current BSS allocation of SPL is as below:
size spl/u-boot-spl

 144572	   5484	   1752	 151808	  25100	spl/u-boot-spl

But 20KB is allocated currently for BSS. Reduce it to 4KB and
save some space for stack.
