I want to propose this patch cause I experience weird behavior on AM62x 
Cortex-R U-boot spl.
Seem that the stack is "restored" to the time dcache_disable was called.
The effect is that the code between dcache_disable
and dcache_enable is executed twice, but the second execution runs with 
wrong function parameters.

Best regards,
