Er, I thought we could define how big the early malloc pool is and not
have this type of problem?

[U-Boot] [PATCH] ARM: DRA7xx: Fix memory allocation overflow

[Andrew F. Davis]

When using early malloc the allocated memory can overflow into the SRAM
scratch space, move NON_SECURE_SRAM_IMG_END down a bit to allow more
dynamic allocation at the expense of a slightly smaller maximum image
size.
