This isn't specific to the SK, more the AM62x in general, suggest name
am62x.rst.

+Build procedure:
+----------------
+1. ATF:

+ $ make CROSS_COMPILE=aarch64-none-linux-gnu- ARCH=aarch64 PLAT=k3
TARGET_BOARD=lite SPD=opteed

These compiler names might not be the same as installed by some current package
managers (-none),
maybe we start by setting up two env vars to point to the two compilers we use:
export CROSS_COMPILE32=arm-none-linux-gnueabihf-
export CROSS_COMPILE64=aarch64-none-linux-gnu-
Then just use those below, that way we only have to switch these first two
commands if we
have a different compiler.
CROSS_COMPILE=$CROSS_COMPILE32
etc..
+2. OPTEE:
+
+.. code-block:: text
+
+ $ make PLATFORM=k3 CFG_ARM64_core=y CROSS_COMPILE=arm-none-linux-gnueabihf-
CROSS_COMPILE64=aarch64-none-linux-gnu-
+
+3. U-Boot:
+
+* 3.1 R5:
+
+.. code-block:: text
+
+ $ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf-
am62x_evm_r5_defconfig O=/tmp/r5
Lets not pollute directories outside of the current one, suggest `O=build/r5`
and the same below.
