On high security devices, ROM enables firewalls to protect the OCSRAM
region access during bootup. Only after TIFS has started (and had
time to disable the OCSRAM firewall region) will we have write access to
the region.
This means we will need to move the stack & heap from OCSRAM to HSM RAM
and reduce the size of BSS and the SPL to allow it to fit properly.
To protect us from overflowing our ~256k of HSM SRAM, add limits and
check during the wakeup SPL build.

In f422c4bec the configuration option to support s28hs512t SPI flashes
was changed from CONFIG_SPI_FLASH_S28HS512T to CONFIG_SPI_FLASH_S28HX_T
to support the wider family. Follow this change in the AM62x EVM
configurations.

Add am62x_evm_r5_defconfig for OSPI Flash support in R5 SPL
and am62x_evm_a53_defconfig for A53 SPL and U-Boot
support.
These configs enable OSPI Flash boot functionality in the board as well
as the usage of OSPI Flash from U-Boot.

Add CONFIG_NR_DRAM_BANKS from am62x_evm_a53_defconfig as this is
needed to calculate the size of DDR that is available.

Add am62x_evm_r5_defconfig for R5 SPL and am62x_evm_a53_defconfig for
A53 SPL and U-Boot support.
To keep the changes to minimum. Only UART And SD boot related configs
are included. This should serve as good starting point for new board
bringup with AM62x.
